The water in my toilet bowl goes down between uses. Where is it going, and how do I fix it?

Question

We got a new toilet put in about a year ago. Recently I have noticed the water in the bowl fills up to where it should be, but if you say.. go to use it the next morning, the water level in the bowl has gone down enough to notice. There is still water in the bowl, but i'd say 1/4 of it is gone. Does this mean there is a leak somewhere? Is that bad? How can we figure out what is wrong without having to remove the toilet?? The floor isn't wet, and neither is the outside of the bowl or anything. Any advice?

Answer 1

if the bowl water is reduced
its being "sucked" down the drain
Pressure differences can "suck" the water in such as if the wind blows across your drain line stack creating a lower pressure in the line resulting in it sucking water into the drain line

this happens, its nothing to worry about

Answer 2

Actually, the flapper ball can't cause water to leave the toilet bowl. What's most likely happened is that you've developed a partial plug in one of the drain system vent pipes that serves the toilet drain and some other drain in the house. Once you've established a level in the toilet bowl and then use the other drain, the water going past the toilet drain connection causes a siphon. Sometimes it will completely drain a bowl, other times it just takes some out. Check your vent stacks for dead birds or bird nests, leaves, etc.

Answer 3

You have a small leak inside your toilet bowl. The "Flapper"..the device that closes after flushing to allow the tank to fill, is not seating or sitting properly. Minerals and rust from your water supply can easily build up in a year. Turn off the supply underneath the toilet tank, flush the toilet till all water is out,then wipe the rubber flapper seat ring with a rag, as well as the underside of the hinged flapper itself. This should eliminate your leak and your water tank level should maintain without further water loss.....

Answer 4

I concluded my identical problem was due to a crack in the bowl allowing water to slowly drain (no external leak observed). I flushed it, then dumped in a slurry of 1/2 cup Metamucil (crazy, I know) and it worked!

Answer 5

until there is something in the J capture in the bathroom,changing it is going to easily reason you extra matters,the previous bathroom has better than a 2 gallon tank,all new ones have are a million.6 gallon tank and it's going to take extra flushes to get an identical outcomes,and could quit up swifter than the previous one,if something possibly you are going to be able to desire to have it snaked out to confirm if there is something inflicting it to quit up,yet changing it won't resolve the difficulty

Answer 6

your talking water in the bowl NOT the tank
air pressure in the trap on either side will fluctuates just because of the weather HI & LO presure can change several times a day...
