My toilet tank won't fill until I turn off the water supply and turn it back
on. After a normal flush, water squirts out of the float and the water
level doesn't rise. Turning the water supply off then on makes everything
work fine, but I have to do it every time I flush. I have a Kohler Rosario
Lite toilet. How do I fix this problem?
Sounds like you have some blockage in your stop valve. First, try
removing the water supply tube from the supply valve. Take a shallow
drip tray (or a shop towel). Once the supply tube is pulled, open the
valve and see if anything washes out. If not, cut the water off to the
entire house and remove the packing nut from the handle on your stop
valve. Carefully remove the handle and pull the whole damn thing.
Clean any debris. Have a helper ease the water back on (just enough to
flush out the 1/2 line supplying your toilet. Tell them only partially
open...and only for 2-3 seconds. Hold a towel or something to catch
the water that is going to spew out. Put it altogether, try it now.
If you still have oddball problems, I would pull the entire ballcock
and replace it with a fluidmaster along with replacing the supply
tube. That way you can be certain that there are not blockages caught
up inside the ballcock.
If none of this works, try the backflushing trick we discussed in
