I replaced the flapper--but why does my toilet still leak?

Question

Flapper in toilet has been replaced.
I called a plumber and he replaced it again. But the toilet keeps leaking.
When I say leak, it is NOT leaking on the floor, but somehow the water is leaking from the tank into the commode.
I called the plumber again and he came out and found that the bottom of the flapper was slimey, only after replacing the flapper after 1 month.
He seemed to think it had something to do with the water and chlorine.
Anyway, he came out again yesterday and replaced the flapper again and about 4 hours later, it was leaking again.

PLEASE HELP!

Answer 1

It's not the flapper but the hole going into the bowl. Turn off the water supply to the toilet and flush. Make sure the tank is empty and then clean the opening to the bowl with lime a way or vinegar. You might have to use a scrub pad to get it really clean. After it is clean rub petroleum jelly(vaseline)around the opening and on the bottom of the flapper. Your problem should be solved. I can't believe a plumber didn't know this!

Kohler Toilet Flapper

Answer 5

My first thought it wrong flapper. Are you sure he's putting in the correct flapper? Universals won't work on all toilets.



"Many toilet flappers look alike, and in many cases a basic corky universal flapper will do fine, but some toilets require a specific flapper , a universal flapper just will not work. Many American Standard toilets, old and new need a specific flapper, Kohler toilets in most cases require a unique flapper, for the specific Kohler toilet you have. Not all Kohler flappers will work on other Kohler toilets."

Was there any cleaning done during this replacement process. Mineral build up and need to be scoured away from the bottom of the tank around the opening.

With a new flapper, it should not leak. If it does, then the flapper seat needs to be changed. Seems like the 'plumber' should have known what type of flapper to use, so it's not likely the flapper. Check to see if you have hard water build up around the rim of the flapper seat. If so, gently remove the grime. Putting a new seat is not that much fun, however. Good luck.

Answer 7

Same problem. Tried 3 brand new flappers same prob. Decided on higher price (extra dollar or two) flapper. 3 seconds fixed. Spent 10 hrs over 2 days tearing apart & putting back together. Flappers that come with kits just would not seal properly & keep leaking.

Answer 8

Water line hose was too far in to the overflow pipe. I took scissors and had to cut off about an inch and a half because it was below the water line and was siphoning water from the tank. This solved my problem. (I replaced the flapper first but the problem continued and then I trimmed the water-feed hose which solved the problem!)

Answer 9

I have the SAME issue. I ve changed the flapper and put a new silicon seal and plastic O-ring, and it still leaks. I can t figure it out.

Answer 10

the whole assembly may need replacing the, cock valve and the flapper as well as the seat the flapper sits on, it sounds to me like its not seating properly buy a kit and replace the whole assembly you'll have to buy the flapper seat separately though.

Answer 11

Check for a crack in the overflow tube. I Had a similar problem of haven replaced the flapper, but the tank slowly leaked and caused water to refill repeatedly. Upon further troubleshooting, my hand accidently bumped the top of the overflow tube. And voila? The top of the tube leaned back a little revealing a crack around the lower part of the tube near the flapper. Each time I lightly pushed the top of the pipe, I could see the hairline crack open and water drain. Instead of changing the entire assembly, I simply sealed the crack. Problem solved.

Answer 12

American Standard Flapper Valve

Answer 13

By leaking, do you mean it keeps running? the bowl fills, but it doesn't shut off? In that case, try bending the arm of the ball cock [round thing on the end of stick] downward. This will cause the arm to raise faster and shut the valve off.

Answer 14

I don't know how much you have spent on this but I just bought a new toilet for 60 bucks on sale and it took me thirty minutes to replace. Oh and it works perfect. Sometimes ifs better to replace the whole damn thing.
