Mission Viejo Plumbing Question: What Causes a Dry Toilet?

One of the strangest bathroom plumbing problems that people come across in Mission Viejo is when a toilet bowl is dry. This can be caused by a number of different problems, most of which you will need a professional to fix.

Cracked Trapway

A crack in the trapway of the toilet can cause the water to drain from the toilet bowl and into the drain pipe below it.  When cracks of this type occur they can be hard to see, especially if the crack happens directly over the drain allowing the water to flow down the drain, rather than all over the floor.  If the crack happens in another portion of the trap-way the drained water can be more noticeable as it flows all over the floor.  A slow leak of this manner might not be as noticeable since constant use will keep the bowl filled with new water, even as the cracked trap-way leaks.  Unfortunately cracked trapways do usually result in toilet replacement.

 Clogged Vent

All drains require air to function properly by relieving pressure within the pipes, and a vent provides this.  A clogged vent on the toilet drain can cause water to pull air down the drain with it, instead of pulling air through the vent.  This will result in the drain pulling a majority of the water from the toilet bowl and down the drain as it tries to find air to pull down to even out pressure in the pipes.  A clogged toilet drain vent must be unclogged so that proper air flow can return to the drain.
