Toilet making "jackhammer" sound
Posted by Mark on June 01, 2002 at 13:42:25:
About two years ago, I installed a Delta floatless toilet valve, the type that uses a diaphram to sense water level and shut off the water. It recently began to make a very loud jackhammering sound in the pipes as it shuts off. Can the valve be adjusted or repaired to stop this, or do I need to replace it?
