Toilet leak- do I need to replace flush valve?


Toilet installed in 2000, and was leaking into bowl, so I put in a new red rubber seal. That didnt fix it. I suspected the surface ridge of the flush valve, so I ran my finger and finger nail along the circumference opf the base of that drain opening. Felt very smooth, no cracks/uneven spots. But after dropping some blue dye, bowl turns blue in 2-3 minutes. Think its time for a new rebuild for flush valve?

Sheesh, that means yanking the tank.........

Thanks

Is there too much tension on the flapper chain?

If it got twisted it will not allow your flapper to seat proper.

Maybe other cause , a loose chain getting under the flapper, flapper attached too high, look for many things before rebuilding.

Not being rude , but it's unclear which device you're referring to . If it's leaking in 2-3 minutes (& you don't hear any ballcock noise) , it's probably the "flapper" valve .

If it is the water inlet valve (ballcock) , you shouldn't have to pull the tank .

The only reason to pull the tank would be to replace the tank to bowl "donut" .

I would use a flusher fixer before yanking a tank. For the simple reason that most flush valve replacements are garbage and tend to leak after replaced. Link

Thnaks, people. Chain is not kinked- I observe inside tank with cover off. One more tip- when I look inside toilet bowl, you can see water "cascading" slowly along the bowl slanted wall.

Cant hear any noise (at least with my moderate hearing loss which is so common among us guys at our age). No hissing, etc, which I have heard before. Now, this flaper valve, isnt that the usually red rubber (silicone?) flapper which pulls up to flush, then seats back down to close the big drain hole? If so, its new.

Quite often the shutoff level gets out of adjustment and allows tank to overflow into the bowl through the overflow tube.

Have you checked the float adjustment?

There are several kinds of float shutoff assembly, I do not know which one you have.

No photo to tell me.

So check the float shutoff.

Re: Toilet leak- do I need to replace flush valve?


REVELATION!! By chance, was just there, peeked inside tank, and it leaked down to only half tank, then stopped. No leakage after that, I made sure. No drizzling down bowl. What does that mean? Leakage in the fill valve, maybe halfway down?

I donrt mean to beat this to death, people, looking like I may have to at least try changing just the fill valve......

Thanks again!

Curioser and curioser.

Sounds like a combination of 2 problems, a leak, and not filling when a low level of water.

You do not need to remove tank to change fill valve, As others stated those aftermarket replacement fill valves are not very good, they are made as universal fit, and from the cheapest junk that they can get.

Try to get a manufacturers one from the toilet maker if possible.

A tip for you, the tank around the fill valve area is weak, do not over tighten the replacement nut, you might crack the tank making it a yard ornament. (flower pot).

Re: Toilet leak- do I need to replace flush valve?


It's hard to understand . You say it's "cascading" into bowl .....but it's not drizzling . And you can't hear water running ?

If the tank level is dropping to 1/2 full , then stopping , I guess you could have a hole in the overflow tube .

Seriously , unless you have 70-80% hearing loss , I would think you'd hear the valve (ballcock) trying to refill the tank ...........

PS: I've simply never seen a flapper valve that was red .

OK, cascade, or drizzle, my fault. It runs down along the back of bowl. And no, no noise. I have about 15% hearing loss, just like most of us,....LOL(did yous even know that? hearing loss is the biggest American epidemic right now).

I should have explained- the 1/2 tank loss was because I shut off the inlet water source. My fault again for no explaining. But still, leak STOPPED at 1/2 tank. Gotta mean something.

Red. Yup, red is what I have seen for years at HD. Unless flapper rubber "valve" is not what i know it as- that rubber stopper that hinges up to open drain, its connected to the chain. isnt that a flapper valve? Or maybe just flapper stopper(?). Sometimes theyre black.

Yep that's the flapper.

I mostly see them black, a few blue ones, and a white one once long ago.
Never saw any red ones though.
Check your overflow tube for a crack or hole near the halfway line.

Does this filler assembly have a small float wrapped around the overflow, that might have wore a hole in it.

Or a different float to shut off the water when tank full?

Re: Toilet leak- do I need to replace flush valve?


Nothing doing, dang. Put all new components (except big black donut). Universal donut wouldnt even come close to fitting, and when installed first time toliel leaked severely within seconds. Old donut seems OK.

So, people. what the heck is it? I even put a tad of silicone o ring lube under the drain tube rubber seal thinking water might leak under there, where it contacts the ceramic tank base. No luck. Still getting drizzling of water. Gotta be either Im not tightening that tube nut enough (I dint dare tighten any tighter), or corroded/rough ceramic tank orfice.

Ive had it, maybe looking at a whole new toilet, sheesh.......

Did you forget #9 above?

Those universal fit units are constructed from sub-par materials and often are garbage.

Shop online at the manufacturers website for a kit and try again.

You might need to leave the waterline shutoff for a few days, but you said that this had it's own shutoff valve.
