Does your toilet empty itself every once in a while? Do you hear the toilet running for a short while even when you are quite sure no one has flushed it recently?
Problem: Toilet Empties Itself Randomly or Toilet Runs on Occasion
Possible Cause of Problem: Poor or No Venting
If your sewage system is not properly vented, problems like this can develop. Sewer vents allow air to flow to the toilet sewage system, which is required for proper function. If the venting is not set up correctly, air pockets get trapped inside the sewer branches can cause a backdraft of sorts known as back-siphonage. If the vent is not working properly, the trapped air tries to escape through the sewer system and pulls the trap of the toilet in a way that causes the toilet to empty from time to time.
If this is the problem, you’ll need a plumber to come out and inspect the venting of your toilets.
Possible Cause of Problem: Flapper is Damaged and Cannot Seal Properly
The water that sits in the tank behind your toilet bowl stays there because of a flapper that seals the tank. Every time you flush the toilet, the flapper is lifted, allowing water to move from the tank and into the toilet bowl. Once the water level of the tank has reached a certain point, the flapper falls back into place, resealing the tank.
If the flapper has deteriorated, the seal is no longer reliable. In many cases the flapper will become brittle or will have accumulated a good deal of sediment, interfering with proper sealing. If the tank leaks enough water out, it will trigger a random flushing. You can solve this by replacing the old flapper, which is not hard to do.
Possible Cause of Problem: High Water Pressure
In some cases, high water pressure can cause a toilet to start running at random times. You can solve this by replacing the pressure reducing valve (PRV). If your toilet is emptying itself, you may have high water pressure problems that will adversely effect your other appliances as well.
