toilet does not have enough water in it now!

[juicymixx]

Hey everybody,

I'm not sure what's going on with my toilet. A week ago my toilet developed a slow leak. I determined that the flapper was warped, so I went out and got a fluidmaster 'universal' flapper that was identical to the pre-existing one in the toilet. I swapped out the old flapper for the new one, adjusting the pull chain, and gave it an inagural flush. And everything worked - that is there was no more leak.
The toilet went through a complete flush, however the final resting water level in the bowl is *much* lower than it used to be. Subsequent flushes do nothing to raise the water level. It appears that the new flapper falls closed far faster than the old one, letting far less water into the bowl (after the flush).
A friend said that the newer flappers are made with different rubber that doesn't hold air as well, so it falls closed faster. I'm not sure that I buy that. Did I get the wrong part, or am I missing something here...

(Just for info, my toilet has a ballcock flush valve.)

Thanks.

Well, it would appear that I'm focused on the wrong thing. It seems like there's not enough water flowing into the refill tube. Is there some way to adjust how much water flows into the refill tube?

Or is it time for me to replace the ballcock with a newer float cup fill valve?

Thanks.

newer materials have different propertis so I wouln't worry bout it. make an adjustment in your tank float and see what happens.

Rotate the disc of the fuidmaster flapper to adjust the length of time that it stays open.

I prefer the Korky flappers myself.

there is a 1/4 inch tube that goes from the ball cock or shut off valve in the tank into the overflow tube that fills the bowl up after every flush. Make sure its in the overflow tube and not filling up the tank and that it has water coming out of it into the overflow tube
