My toilet bowl begans to loose water after I flush it. It flushes good but once it fills, water slowley leaks out. The floor does not get wet, so I can't figure out way this happens.

There are a few things that could take your level down. There could be a crack in the bowl letting the water seep out over twenty minutes. That would be my first guess. My second guess is kind of far out but since I've had a couple of calls that lost water in the bowls, I'll throw it up for grabs. The water in your bowl is a trap/seal and connects directly to a pipe called a vent located on your roof. If that location is windy, it has been noted that the wind blowing over the vent pipe causes a suction that syphons the water out the bowl. But that's rare and you will notice the level raising and falling as it happens. I'm going to go with door #1 if only because of the time it takes for the level to go down. The only fix I know is to change out the bowl There could also be a factory defect in the bowl. Sometimes in casting the bowl there is a small bubble in the china. Instead of junking the bowl the manufacture will put a porcelain patch over the hole and send it on through. On occasion the patch will fail allowing the water to seep out of the bowl. If that's the case you would have a full bowl after you flushed and the bowl filled but some time later you would notice a drop in the bowl level. The only other thing might be if you dropped something in the bowl and cracked it. If you're worried about where the water's going, in both cases it drains back down into the sewer and not under the bowl on the floor. To check the bowl must be pulled, filled and put up on saw horses. You can then see if there's any leakage from the bowl. Good luck, Tom

If it slowly leaks down and you see no water, the interior trapway probably has a crack and the water leaks down into the floor drain. It could also be a clogged vent and water running past the toilet pulls the trap dry. One way to check the internal crack is to fill the bowl, put food coloring in the bowl and then leat it drain down. Pull the toilet, turn it upside down and look for color stains in the trapway.

Hey ma0641,
Before you post check the date in the upper left hand corner. You just responded to a two year old dead thread. Have a good one, Tom

Yes, what happened was I was looking at similar threads and opened this one by mistake. I cut and pasted the answer in the new thread. I figured someone would pick that up, Brian
