Toilet running constantly from a worn flapper
Why it happens here
North Country's mineral-heavy water coats the flapper with scale, preventing a clean seal. The flapper stays slightly open, and the fill valve keeps refilling the tank. It is the single most common call we get here.
Our approach
We replace the flapper with a quality Korky or Fluidmaster unit, clean the valve seat, and adjust the chain. Most jobs take under 30 minutes, and we check the fill valve while we are in the tank.
