Toilet running constantly from a worn flapper
Why it happens here
Hard water in Windwood Township leaves mineral deposits on the flapper, so it stops sealing against the flush valve. The rubber also hardens with age. Most flappers here fail within five to seven years.
Our approach
We replace the flapper with a hard-water-rated model and descale the valve seat. We also check the fill valve while we are in the tank, so you do not pay for a second visit a month later.
