Plumbing Tip: How to Fix Leaky Tub Faucets in Showers

Monday, June 4th, 2012

Do tub faucet leaks sound like a familiar issue in your Orange County home? You turn on your shower, flip the switch to go from tub faucet to shower head and the tub faucet continues to leak. Not only is it rather irritating, but it draws from the water pressure in the shower head. Let’s take a look at why this happens and how to quickly fix it.

Why the Leak?

There is a valve in your tub’s faucet that diverts water from the tub to the shower head when the switch or lever is pulled to turn on your shower. Because the valve is not a perfect seal, the tub faucet will drip a small amount during a shower. However, if a large amount of water is coming out of the tub faucet and very little is coming from your shower head, it is likely a problem with that valve.

In some cases, the only way to know the root of this bathroom plumbing repair is to take apart the assembly and check all of the valve parts individually for damage. The specifics of the repair process will depend largely on the type of shower and diverter valve you have.

Fixing the Problem

To fix this problem, you can either replace part of or the entire shower diverter valve. Start by removing the faucet and pulling the screw that holds the shower diverter valve in place. Once the screw is removed, take out the rubber washer and replace it. Many times, this is enough to fix the problem.

If it is not, however, you may need to replace the entire shower diverter valve. There are some situations that make it hard to reach the shower diverter valve, such as when you have a shower handle instead of a faucet knob. If this is the case, you may need special tools or professional assistance in removing the knob to access the valve.

If you find that this does not fix the problem or that you are uncomfortable attempting this repair, contact Saddleback Plumbing who is experienced in removing and replacing shower diverter valves.

What to do When Air Conditioning Coils Freeze Over in Orange County

Monday, April 30th, 2012

Here are a few reasons air conditioners in Orange County can develop cooling coil icing problems; either the air filter has not been properly replaced, or there is a condensing coil leak.  It is best to check and test the easiest problem first and then move on from there.

It is important to perform the air conditioning maintenance of changing the filters as often as recommended by the manufacturer.  A common result of not replacing filters frequently enough is a buildup of dust and dirt on the filter, which causes reduced air flow throughout the air conditioning unit.  With reduced air flow, the evaporator coil or cooling coil within the air handler can become blocked by ice or frost build-up.  Having cooling coil icing can significantly reduce or completely stop the amount of cool air being produced by an air conditioning unit.

Easy steps to diagnose and resolve air conditioning cooling coil icing problems:

  • Visually inspect the air conditioning cooling coils to check whether reduced air flow has been caused by cooling coil icing.  If ice or frost is found on the coils, thus blocking air-flow, proceed with the next step.
  • Turn off the air conditioning system completely to allow ice to evaporate, the unit will have to remain off until all ice is completely melted and drained away from the unit
  • Unclog the condensate drain to ensure proper drainage of melting ice
  • Replace all dirty filters on the air conditioning unit
  • Once the a/c unit is de-iced and has fresh filters, it is safe to turn the system back on, to test whether the icy build-up happens again

If after completing these steps, when the air conditioning unit is turned back on the cooling coils do not ice-up, the unit runs normally and cool air runs smoothly through the system, congratulations!  That do-it-yourself attitude paid off; the problem has been fixed!

If after completing these steps, when the air conditioning unit is turned back on cooling coil icing happens again, this could mean one of two things.  Either too little of the refrigerant is being released into the cooling coil due to a clogged capillary tube or a stuck thermostatic expansion valve.  Or the refrigerant charge is too low due to a refrigerant leak.  A refrigerant leak can happen at any point in the refrigerant piping system which would then need to be soldered and resealed, or it can happen in the cooling coil or condensing coil which could mean the entire coil needs to be replaced.  Fixing of refrigerant leaks should be handled by a HVAC professional.  Contact Saddleback Plumbing so we can identify the air conditioner cooling coil icing problem and execute the proper solution.

HVAC Tips: The Differences Between SEER and HSPF Ratings

Wednesday, March 7th, 2012

When it comes to heat pumps in Orange County and across the country, there are two different ratings you’ll often see – the SEER and the HSPF. So, what does each of them mean and which rating is more important when purchasing your new device? Here are a few things to consider:

SEER

The acronym SEER is short for “seasonal energy efficiency rating” and is used most commonly to measure air conditioner efficiency or in this case, the cooling capacity of your heat pump.

HSPF

The HSPF is short for “heating seasonal performance factor” and is a measurement of how efficient the heat pump is in producing heat during the cooler months of the year.

The Difference Between the Two

Every heat pump will have both of these ratings, allowing you to see how efficient each is. This is important because you need to know for certain how well your heat pump will perform under certain situations – both in the winter and summer.

However, if you live in a colder climate where the summer rarely calls for air conditioner, your focus should be on the HSPF first. And if you live in a warmer climate where your heating needs are minimal, the SEER is most important. Another thing to consider is your supplemental heat. If the cost of your supplemental heating system is high, you’ll want an HSPF that is as low as possible to balance it out.

Choosing an Efficient Heat Pump

Heat pump efficiency directly impacts the price of the device you purchase but is almost always worth the difference. The key is to find a device that provides what you need based on where you live. Keep in mind as well that, like most HVAC upgrades, you won’t immediately recoup the cost of the device in your energy savings, so if you plan on moving soon, you should purchase a more affordable device now and upgrade later.

Purchasing a heat pump is an important step in making your home more energy efficient. If you are unsure which rating you need or how to analyze their meanings, contact Saddleback Plumbing to learn more.

How to Calculate Duct Size for an AC System in a Los Alamitos Home

Wednesday, February 22nd, 2012

Duct sizing in Los Alamitos is a complex process using one of three methodologies. The goal of duct sizing is to provide the perfect space through which heated and cooled air can travel around your home. Ducts should provide ample air flow to keep you comfortable without overworking your HVAC system or costing you an arm and a leg on your energy bill.

Methods Used for Sizing

There are three methods used for most modern duct sizing. The first is the Velocity Method. The velocity method takes into account the speed at which air flows through the ducts based on their general size. A series of equations is used to determine this, including duct cross sectional area, air flow rate and air speed. A much more detailed breakdown is available on the EngineeringToolbox.com for those interested in the math behind the process.

In general though, the velocity method allows contractors to determine the appropriate size and layout of ducts based on their application (residential, commercial, industrial or high speed) and their position (main or branch ducts).

Contractors may also use the Constant Pressure Loss and Static Pressure Recovery methods to design ductwork for your air conditioning installation. The constant pressure loss method tends to result in more components but provides a more accurate reading of the actual pressure loss in the system based on the materials used and the layout of your ductwork.

Static pressure recovery focuses on ensuring the same pressure level is achieved at all vents and inlets for the system. It is probably the most complicated sizing method, however, so it is rarely used for air condition system installations.

Simplifying the Process

Were we to break down the process into its core components, this is what a contractor would do when sizing your duct work:

  • Determine CFM for Each Room – using the Manual J for load calculations, they would determine the CFM. This is based on the (Room Load/House Load) x Equipment CFM. The entire house must be measured and load calculations completed before this can be done.
  • Friction Loss Rate – Friction loss rate is the (Available Static Pressure x100 / Effective Length).
  • Duct Sizing – Finally, the contractor will use a chart or software to select ductwork based on the friction loss and CFM calculated in the first two steps.

The goal of all of this math is to ensure that the HVAC system installation is exactly as large as is necessary to distribute heated or cooled air to the entire house. Incorrect measurements result in improper delivery of that air and a system that doesn’t quite get the job done.  If you have any questions about this process please contact Saddleback Plumbing.

How Bad Is the Air in Your Home? Saddleback Plumbing Investigates

Wednesday, October 12th, 2011

Every day in Irvine you hear about another awful contaminant that can get into your home’s air supply. Radon gas. Carbon Monoxide. Nitrogen Dioxide. Smoke. Mold. The list gets longer with each passing year and many homeowners are understandably worried. However, before you run out and by the newest lineup of filters, purifiers, and UV lights, stop and think about just how bad your indoor air actually is.

When Was Your Home Built?

Homes built in the last 10-15 years tend to be well ventilated and may even have air quality systems already in place. It’s those built in the late 1970s and early 1980s that tend to have the worst ventilation (assuming they have not been updated since then).

This kind of poor ventilation can be dangerous, but usually only in that you have less fresh air and more indoor allergens and contaminants. Specifically, you’re most likely to suffer from things like pet dander, dust, pollen, and dirt in the air. On their own, these are not dangerous, but without fresh air to circulate them outside and ensure you get a steady, clean supply of air to breathe, they can make you ill.

How Bad Can It Get?

While it’s rare, some homes suffer from more advanced contaminations. The most common is mold. Mold grows primarily in dark, damp spaces. If your humidity levels get too high in the summer, the ductwork in your house is perfect for mold and it will blow the spores directly into your air, putting everyone at risk.

Outdoor contaminants can also make it into your indoor air. Things like exhaust and smoke, gas, radon, or other outdoor pollutants should be tested for when you setup a new indoor air quality system. There are filters and purifiers that will remove almost all of these contaminants, but they are not always required, so you should check before making a decision.

Ultimately, the odds are that your home suffers only from some stale, dusty air. But, it is very important to keep everything clean and test it regularly to make sure nothing worse develops. Poor air quality is about more than just comfort – it’s an honest health issue.

Different Types of Refrigerants Used in HVAC: Some Pointers From Los Alamitos

Monday, August 22nd, 2011

We have all heard the phrases in Los Alamitos like “save the planet” or “save the ozone layer.” Up until the 1960s there wasn’t a lot of attention paid to the disintegrating protective ozone layer around the Earth’s surface. Since then, ozone-depleting CFCs (chlorofluorocarbons) have been seen as the ozone-depleting culprit and new laws regulating the use of CFCs have had a direct impact on heating and cooling (HVAC) systems.

The “lifeblood” of any air conditioning and heat pump system is its refrigerants – a chemical used in the refrigeration cycle. For several decades, the “refrigerant of choice” in HVAC systems has been HCFC-22, also known as R-22. The problem is, HCFCs (hydrochlorofluorocarbons) are harmful to the ozone layer because they contain ozone-destroying chlorine.

Because of this, the use of R-22 is being slowly phased out from usage in HVAC systems. The Clean Air Act of 1970 has provisions in it to phase out HCFC refrigerants. As a result, chemical manufacturers will no longer be able to produce, and companies will no longer be able to import, R-22 for use in new air conditioning equipment (effective this year),  but they can continue production and import of R-22 until 2020 for use in servicing existing equipment. So, R-22 should continue to be available for all systems that require R-22 for servicing for many years to come.

But the “new kid on the block” replacing R-22 has been getting up a head of steam for several years now. Among the new alternative refrigerants recommended by the U.S. EPA is R-410A, a blend of hydrofluorocarbons (HFCs) that does not contribute to depletion of the ozone layer, but, like R-22, contributes to global warming. R-410A is manufactured and sold under various trade names, including GENETRON AZ-20®, SUVA 410A®, Forane® 410A, and Puron®.

There are several other substitute refrigerants going by the names of R-407C, HFC-134A, and R-422C. A complete list can be found at www.epa.gov.

According to the U.S. EPA, homeowners with existing units using R-22 can continue to use R-22 since there is “no requirement to change or convert R-22 units for use with a non-ozone-depleting substitute refrigerant.” And it is important to note that R-407C is allowed for retrofits but R-410A is not, due to its higher working pressures. Substitute refrigerants would not work well with existing components unless a retrofit was made or in the case of using R-410A, a complete system changeout.

One of the leading causes for air conditioner and heat pump failure are lower levels of refrigerant. If you are working on your own equipment, it is important to note that replacing refrigerants like R-22 and R-410A should only be done by certified HVAC professionals. You must show EPA certification to purchase these refrigerants.

If you are interested in “saving the planet” you might do well to give the boot to your HCFC-consuming appliance.

The Energy Star Label

Friday, June 24th, 2011

The Energy Star program is a joint program of the US environmental protection agency and the US department of Energy. The program’s goal is to help consumers save money and protect the environment through energy-efficient products and practices.

The best-known aspect of the Energy Star program is the Energy Star label, which is awarded to appliances and other items that are significantly more efficient than average. Energy Star efficiency guidelines vary depending on product category, but in general, Energy Star products use 20%-30% less energy than minimum federal standards.

The Energy Star guidelines were designed both with energy efficiency and performance in mind. While low energy use is one of the most important criteria for selecting Energy Star appliances, product performance, features, warranty, safety, and durability are also taken into account. Price is also a factor: if a product costs significantly more than other products in its category, it will only receive the Energy Star label if the up-front cost will be recovered through savings in operating costs within a reasonable amount of time.

The first Energy Star labels were given to computers and monitors in 1992. Now labels can be found on many other products, including:

  • Furnaces
  • Hot water heaters
  • Air conditioners
  • Dishwashers
  • Refrigerators
  • Light bulbs (florescent and LED)
  • TVs

Energy Star products can be found wherever appliances and electronics are sold. Look for the blue and white Energy Star label. You can also look for the yellow EnergyGuide label that is affixed to most heating and cooling systems and household appliances. This label is created by the Department of Energy and shows a product’s annual cost of operation compared to similar models. It will often indicate whether a product is Energy Star.

It’s important to note that while an Energy Star label indicates that a heater, air conditioner, or household appliance is more efficient than the minimum guidelines, it does not always mean that you are getting the most energy efficient option on the market. If you are making a major appliance purchase, use the Energy Star label to be sure every model on your “short list” is energy efficient. Then, look carefully at the EnergyGuide label to compare the efficiency of the models you are considering.

The EPA has also extended the Energy Star label to cover new homes and commercial and industrial buildings. To qualify for the Energy Star rating, a new home must use at least 15% less energy than standard homes (built to the 2004 International Residential Code). Energy Star homes usually include insulation, high-performance windows, energy-efficient heating and cooling systems, appliances, lighting, and water heaters.

The Energy Star standards and label have been recognized in many other countries, including Canada, Australia, Japan, New Zealand, Taiwan and the European Union.

What Is the White Substance around My Showerhead and Faucet, and Why Is it There?

Monday, June 13th, 2011

For many people, it is common to notice a buildup of some type of white substance on showerheads and faucets around the house. Of course, this looks bad and would seem to indicate a problem. But what is it really? And what can you do about it?

Well, to begin with, this type of buildup is usually nothing more than mineral deposits. The minerals are in the water that flows through the faucets and can settle out on the fixtures, particularly in the shower where a lot of the water you use evaporates. When the water evaporates, it leaves these mineral deposits behind, and they can cause quite a buildup over time.

In areas where the water is very hard, this type of buildup problem will be greater, but it is actually a relatively easy problem to fix. The best way to get these mineral deposits off of your shower and faucet fixtures is to allow them to soak in vinegar overnight. After an appropriate period of soaking, the mineral deposits should come off easily with moderate scrubbing.

But no matter how many times you remove these deposits, they will always come back. They are simply a result of the makeup of your local water, and so unless you take greater action, you will have to repeat this process on a regular basis if you want to stay residue free.

However, there is another option. Rather than having to soak all of your fixtures in vinegar every so often, you may want to consider having a water softening system installed in your home. These systems are appropriate in areas where the water is very hard and they can go a long way towards eliminating buildup of sediments and minerals all over your home water system.

Why the SEER Is Important When Choosing an Air Conditioner

Friday, March 25th, 2011

There are many things to take into account when you are trying to pick out a new air conditioning system. You want one that will be powerful enough to cool the required space but not so big that it turns your home into a walk in freezer. With so many models and types on the market, it can be difficult to figure out what details you need to pay attention to and what you can ignore.

The seasonal energy efficiency rating (SEER) that each air conditioner comes with is not something you should ever disregard, however. This number is a reflection of the overall energy efficiency of the unit and it can have a huge impact on the amount you pay to keep running your air conditioner every month. The higher the SEER of a product, the more energy efficient it is and the lower your monthly bills will be.

Of course, air conditioners with a higher SEER also generally come with a higher price tag, so you will have to weigh the amount of your potential savings against the difference in price of units with different SEERs.

To calculate this, you will need to know exactly how much more energy efficient one model is compared to the others. For instance, when you know that an air conditioner with a SEER of 11 is 7% more efficient than one with a SEER of 10, you are in a better position to evaluate the potential savings.

You will still need to translate this into dollars, of course, because the amount you save with a 7% boost in efficiency will depend largely on how much you typically pay already. If you are only paying around $320 a year with a SEER 10 air conditioner, upgrading to a SEER 11 will only save you about $30. However, if your annual cooling bills are closer to $1000, you will easily save close to $150 with this small upgrade.

SEER numbers go much higher than 10 and 11 too. In fact, the highest you will probably get is a 19.5 SEER, but that will more than cut your cooling bills in half if you are starting with a SEER 10. Still, the actual amount that you will save depends on how much you were paying to begin with, but if your cooling bills are already very high, it may be worth it to invest in an expensive but very high efficiency system.

Green Your Plumbing

Monday, January 31st, 2011

These days, “green plumbing” is getting increasing attention, especially in dry areas like the southwestern US.

“Green plumbing” helps the environment by doing one or more of the following:

  • Saving water
  • Saving energy
  • Using environmentally-friendly materials

There are a wide range of green plumbing products that can make a big difference in how much water and energy your home uses. They range from simple accessories that cost less than $20 to major home remodels. Here are a few of them, ranging from the simple and immediate to larger investments with a longer-term payback.

  • Low-flow showerheads and faucet accessories (often called “aerators”). Check the side of your current faucet and showerhead to see if they use more than 1.5 GPM and 2.0 GPM, respectively. If they do, you can benefit from an upgrade. Look for the EPA WaterSense label to be sure that your new showerheads and faucet accessories are water-efficient.
  • Hot water heater blankets and pipe insulation.You don’t need to insulate your hot water heater and  pipes to prevent freezing, but doing it will save money, water, and energy, and (as a bonus) you’ll enjoy hotter showers in the winter. This is a simple DIY job and the materials are extremely affordable.
  • Touch-free faucets. When you’re not actively using them, touch-free faucets shut off. According to industry estimates, the result can be a water savings of up to 70%. Touch-free faucet technology has improved greatly in recent years, and sensors are now very reliable. If you like your current faucet and want to keep it, there are also touch-free faucet conversion kits.
  • Dual-flush toilets. As the name suggests, these toilets have two different flushes: a “half-flush” for liquid waste, and a “full flush” for solids. Dual-flush toilets are standard in many European countries and are becoming increasingly popular in the U.S. because of their water-saving potential (up to 68% over conventional toilets) and sleek styling.
  • Tankless water heaters. Unlike conventional tank heaters, which use energy constantly to maintain a reserve supply of hot water, tankless heaters only use energy when hot water is needed.  Tankless water heaters are not quite “instantaneous”, as some manufacturers claim, but they provide hot water within a few seconds. Good quality heaters can provide hot water to multiple fixtures simultaneously.
  • Sprinkler system upgrades. Much of the water from spray sprinkler systems evaporates. Trickle and drip irrigation systems can improve water efficiency by delivering smaller amounts of water directly to the base of the plant. Other products, such as pressure regulating spray heads and rotors and automatic rain sensors, can also save thousands of gallons a year. Another option is to re-use laundry waste water by diverting it into the garden. This can be a DIY project or can be built directly into your plumbing. Check with your local authorities to find out if this is permitted in your area.
