Hi. My toilet water (in the tank at the back of the toilet) is running
non-stop. I tried shutting off the valve underneath the toilet, but it wouldn't
budge in either direction. I removed the lid off the tank, and rather than the
usual ball-type float, there is a device called a "Fluidmaster." Do you have
any suggestions just so I can stop the water from running continuously all
night? Thanks for your help!

The float on the FluidMaster is a plastic "bucket" that rides up and
down on the central post. Try pushing the bucket down and then back up
a few times. Sometimes that will stop it.

If you're unfamiliar, I don't recommend tampering with the stuck
shutoff under the toilet; if something breaks you will be SOL.

Best thing you can do is shut the main valve off to the house.
With pressure relieved, you can take the top cap off the FluidMaster
by rotating a qtr turn. Under the cap will be a rubber "seal"
which is easily obtained at any hardware/HD.
