Toilet bowl losing water

Author: eagles (WI)

I recently replaced my old toilet with a new. When the bowl fills it loses about 3" of water. No water is lost in the tank and it's not overfilling. The toilet I took out never did this. This is a toilet below another toilet on another level and that toilet is fine. When I flush the good toilet the water in the bowl of the bad one will move. I thought it would be a vent issue so I went on the roof and flushed it twice with a garden hose. That didn't help. When I add a 5 gallon bucket of water to the bowl it goes right down immediately. It doesn't hold the water. There are no leaks anywhere. Can somebody help me with his? thanks

Author: eagles (WI) Is it right when I add a 5 gallon bucket of water to the bowl that it drains out almost immediately? Shouldn't the water stay in the bowl?

Author: hj (AZ) Pour water into the bowl slowly, until it reaches its maximum height. THEN observe what happens to the water level. If you dump 5 gallons into the bowl, it SHOULD evacuate all the water except for a small amount which "drops back" after the flush.

Author: North Carolina Plumber (NC) How long does it take the bowl to lose it's water ? Does it lose it even if the downstairs toilet is not flushed ? It very well could be a crack in the internal trap, you might even be able to hear the water trickling down into the drain pipe.

Author: eagles (WI) It loses water in the bowl right after a flush. When the toilet upstairs(the good toilet) flushes you can see the water line move in the downstairs bad toilet.

Re: Toilet bowl losing water
Author: hj (AZ) you are being vague. Does the bowl fill with water after a flush and then the water "disappears", or doesn't the bowl refill after a flush?
