no tank refill unless water supply is turned off and then on
My toilet tank started to fill very slowly - taking about 30 minutes to refill. Having galvanized pipes, we had a plumber repipe the house thinking this was the problem (along with other symptoms). Now the toilet tank won't refill unless you turn the water supply off and then on again. It has a Fluid Master 703AP4 tank mechanism. Nothing appears to be broken.
