    Default Norris One piece Toilet water seeping in the toilet bowl

    Hi,

    We have been facing an issue of water seeping into toilet bowl forcing toilet tank to fill periodically - as water level goes down periodically. We replaced the flapper (blue rabbit ear one) multiple times w/o any success. We also tried cleaning the brass flush valve to remove sediments during the replacement of the flapper. We were thinking of replacing the toilets to avoid wasting the water but wanted to check if we can address the issue w/o replacing the toilet - as toilet it self is working fine. Note: This toilet must have installed during 1993.

    btw, we ensured the water is leaking into the bowl by putting colored dye (one get it from Ace Hardware) in the toilet tank.

    Would appreciate any pointers/help.

    Thanks!

    Rub your finger around the seal where the flapper goes...if it is rough or has a chip or lump on it, the flapper can't seal properly. Some flappers have both ears and a ring...if yours do, do NOT use both, cut the ring off so only the ears are holding the flapper...using both can often distort the thing, warping it and preventing it from sealing.

    Last thing, the gasket that is holding the flush valve assembly is held together with a big nut on the bottom of the tank. If that is loose or the gasket degraded, it can leak. You may just need to remove the tank and tighten the nut holding things in place.

    That is a builders graded toilet, probably not a good flush performer. But it can be fixed, and if you otherwise have no problem with it, you should fix it since a new one piece will be pricey.

    Look for 3 bolts outside the perimeter of the flush valve. Try just tightening them up. If that doesn't help, remove the flush valve ( held in by those screws) and get a new gasket, or a whole new valve/

    Hi,

    Thanks for the suggestion but I couldn't find 3 bolts that you mentioned. I'm attaching couple of photos of flush valve. Would appreciate if you have any suggestion on replacement part and/or how would it cost.

    Thanks. I definitely noticed the surface is not smooth. Not sure what caused it. Since it is a one piece toilet there are no nuts below the tank.

    Yuuuuuuuuuuup.... the seating surface is pitted. The big screw down there is what will remove the flush valve. You might even get away with dressing the seat with some emery.
