Another toilet running thread... flapper seals but wont fill

I'm confused (again)... I installed a new fluidmaster 400 float assembly last week. now, the water runs into the overflow tube fine, the float seems to function as it should when i manually lift it, but the tank won't fill. I checked the flapper and the seal is good, but is there another thing associated with the overflow assembly that is allowing the water to drain? I pour water into the tank and it won't fill up. Will removing the tank and tightening the overflow seal fix it? It's just odd that it started all of a sudden, so I wouldn't think the tube is cracked? or am i just stuppid about something here?

Do you constantly see ripples in the bottom of the bowl?

Maybe not. Put some pressure, on it. See if the water flow stops.

Sounds like the float is set to high. If a float on a rod. bend rod down a little. If float is around fill tube read instructions on how to adjust.

There is no overflow under the flapper on a 'normal' toilet.

The flapper rests on and seals the flush valve. It sounds like the flush valve might be loose.
Tightening the flush valve requires removing the tank.

try this shut water off. pour food coloring in tank and see if water in bowl changes color. If color changes you have a leak to bowl. either at flush valve or seal between tank and bowl.

I don't see how a new overflow assembly would solve the problem. I still think that the flapper needs to be replaced.

Try what pugsl said.

Agreed, replace the flapper and adjust chain properly. Forget replacing the flush valve for now.

Post a picture of the entire inside of the tank, showing how new fill valve was installed.

Flapper Chain

The chain which lifts the flapper is too long. The slack in the chain can get under the flapper and cause the flapper to not seat fully on the flush valve. Shorten the chain to where it has some slack but not enough to allow the chain to get under the flapper.

yeah... i took the pic before I adjusted it... after doing this I came back later to water on the floor around the toilet base, so I replaced the entire overflow assy. Came back later with more water, so I had to tighten the tank bolts more. Then the shutoff valve leaked all over, and fortunately, i could tighten the packing nut to stop it. When will this toilet from hell ever end??? Now the seal will prob start leaking to make it a total redo!!!

Flow Rate

The Fluidmaster valve needs to be flushed. Sediment in the valve will cause slow flow rate.

I wonder if the flush valve seal was in bad shape, but holding, but when you installed the fill valve and had your hands in the tank, a little push one way or another on the flush valve caused it to now leak. Id replace the flush valve. I see a lot of black around the flush valve, but I guess maybe that could be sediment collecting there since that is where the water exits the tank.

Just a thought.
