A lady called on behalf of her father, who said the upstairs toilet valve had been hissing continually for a few days. We found that the refill valve was defective and replaced it.

This valve is located in the tank, typically on the left side. It refills the tank automatically once the toilet is flushed. If this valve is blocked, higher-than-normal water pressure inside the tube will cause vibrations and emit a hissing sound.

You can take care of this repair yourself by going to your local hardware store and purchasing a new valve. You’ll need to turn off the water supply to the toilet, flush, and then dry the inside of the tank. You’ll see a large metal or plastic nut underneath that secures the toilet to the water supply pipe. Remove the nut, being careful not to damage the pipe. You’ll see a second nut that secures the refill valve to the tank. Remove that nut, take out the old valve and replace it with a new one. That should take care of the problem, but if it doesn’t, give us a call.
