How to fix a leaking and running toilet | Korky Toilet Repair
Did you know that the toilet flapper is the #1 issue leading to running and leaking toilets? Don’t worry, changing a flapper is easy. No need for a plumber. Neglecting a leaking flapper can result in costly water waste. Here are a few tips to identifying a flapper leak. Step 1: take a cloth and wipe the sealing surface of the flush valve. Deposits can stick to the flush valve opening and prevent the flapper from sealing. Step 2: check the flapper chain. The chain should be as close to vertical as possible and have minimal slack. Step 3: place a couple drops of food coloring in your toilet tank. Wait 15 mins and check your toilet bowl. If the bowl water changed color, you have a leaky flapper and it’s time for a replacement.
