Note there is no water leaking outside of the toilet I contacted kohler and they said the only way for the water to leak into the bowl is either the flapper or the flush valve gasket is malfunctioning I replaced the flapper with a new one but it's still leaking, so perhaps it's the flush valve gasket. If a leak occurs at a flush valve gasket in new installation, the lock nut securing the flush valve to the underside maybe leaking Fluidmaster instructs that the flush valve lock nut should be tightened no. Understanding the flush valve seal the flush valve seal, also known as the flapper, is a rubber or silicone component that sits at the bottom of the flush valve
Its primary job is to create a watertight seal, preventing water from leaking into the toilet bowl when the tank is full Over time, the seal can wear down, become brittle, or get damaged, leading to a leak Is your toilet constantly running or leaking One of the most common causes of a toilet leak is a faulty flush valve This small but essential component is responsible for regulating the flow of water from the tank to the bowl When it fails, water can leak from the tank into the bowl, wasting gallons of water and potentially causing damage to your bathroom
