I have a toilet that I just replaced the Fluidmaster valve with an
American Standard shutoff valve and new flapper.
The problem I was having before was that the tank was not filling and
the toilet would run for a very long time.
Now that I replaced the Fluidmaster, the tank will fill, but it takes
a very long time to do so (8 mins).
I first tried to open up the toilet water supply to get more water
flowing, but when I do, I get violent vibrating of pipes from the
valve and the kitchen sink water filter and pipes. So I keep the
toilet water supply barely on to keep the water flowing, but it's too
low of a flow to fill the toilet quickly. What can I do about this?
I'm afraid I introduced the problem when I followed the FluidMaster
website trouble shooting tips of removing the seal of the fluidmaster
and turning the toilet water supply on and off a few times (trying to
dislodge any particles/debris). But the water supply used to operate
full on without the noise in the pipes. But after troubleshot and
installed the new shutoff valve, I get the noise.
