Toilet Tank leak

kenitech · Tuesday at 10:31 AM

I'm sure you guys have seen this post a million times. Here's a million and one!
I replaced this assembly cause there was a slow leak in the tank. It doesn't seem to have stopped the slow dripping sound I hear. There's no water outside the tank so I'm pretty sure it's dripping here.

Also, what are those 3 rubber plugs? I also replaced those since they came with the kit. Why are those even there in the first place? I thought maybe water might be leaking there but they seem pretty tight. The water seems to leak completely out, in other words, below where the flapper sits so I suspect it's the way the assembly is sitting. There doesn't appear to be any debris between the seal. Do I put putty at the seal?? Is it possible the shape of the tank itself is slightly curved and it won't sit right? Am I not tightening it down enough? I can push this thing down with my weight and still hear water trickling. Is this a low quality, off brand part and I need a name brand?

the part is from Greydock : FlushLine Replacement for American Standard 047107-0070A Flush Valve Assembly

Do I just buy a new toilet and call it a day?

I would get one of those dye leak-test kits that you pour into the water tank. After I flushed the toilet and let the tank refill, I would pour the stuff into the water closet and check the water level in the tank. I would not flush the toilet for several hours.

If the flush valve is leaking the water level in the tank will have dropped and you should see the dye in the toilet bowl. If it's leaking, I would then buy a standard Flapper kit, one that doesn't have any goo-gaws on it, install it and see what happens.

I have not the foggiest idea what would cause the water level in the tank to be down and there be no dye in the toilet bowl.

Thanks!, appreciate the tip!

Those three rubber "plugs" may be the tank-2-bowl mounting screws. PS, you could probably use food color to do the dye test and save yourself the cost of a "kit".

I'm going to try a small amount of silicone in the holes and plug the holes with the rubber plug thingies. I 'suspect' that there is a small irregularity in the hole size and the rubber is not stopping completely. Last few folks I spoke to said I'm better off just getting a new toilet. Bathroom hasn't been touched since the 50's so that is an eventually plan. Just need a temporary fix for now.

I *think* those holes might actually be there to insert a tool to prevent the metal bracket thing from spinning while you tighten down the flapper assembly. Although those metal pieces are not long enough. Good call on the mount but I didn't see a screw. Is it possible that this toilet is all one piece??
