My toilet bowl is dry?

Question

We recently replaced the flapper in our toilet - that part is working fine. Now we have a new problem; a few minutes after the flush has completed - the toilet bowl runs dry. I have never seen an empty toilet bowl - especially when the tank is full. Can anyone suggest a reason why my toilet bowl is dry? There is no water on the floor or area surrounding the toilet. This has my husband and me both baffled.

Answer 1

Try sticking your head in it.  

Answer 2

It sounds like you have an induced siphon which is caused by your vent pipe being clogged or partially so.  If the soil pipe is plugged when the toilet is flushed air cannot enter the system behind the "flush" and that creates a negative pressure in the pipe that sucks the water out of the toilet trap.    

Answer 3

Hmmmm I guess that your flapper is closing too quickly...because the chaing is too short

Answer 4

If there is absolutly no water in the bottom of the bowl you do have a leak, probably a crack and the water could be leaking into the sewer pipe. Toilet would need to be replaced. If there is some water in the bowl then the answer about the fill tube is most likely your problem.

Answer 5

The fill line should extend from the fill valve, to the flush tube.  Try filling the toilet with water, to the normal water level.  Now leave it alone for awhile, and don't let anyone use it.  If the water is gone, you have a cracked bowl, and it will need to be replaced.  If the water is still there, after a reasonable amount of time, try flushing the toilet, and watch how it reacts.  If the water starts slowly draining out, you probably have a partially stopped up sewer main.  Look outside the house for a cleanout, and open it.  If the system is working properly, you will not see any standing water.  But if there is water in the pipe, you will need a sewer snake to clear the line.  Good luck!

Answer 6

is the fill hose in the tube

Answer 7

while working on your toilet it rocked back and forth breaking the seal on the wax ring  try replacing it. if that doesn't work you may have a cracked bowl.
