FAQ

Can you fix a leaking flush valve?

A popular fix for the issue is to replace the flapper that seals the flush valve opening. This can be done effortlessly by using a repair kit.

These additional components are designed to fit snugly over the existing flush valve opening, ensuring a comprehensive and effective solution.

What happens if flush valve seal leaks?

If the rubber gasket that seals the flush valve inside the tank is worn out and leaking, it can cause the water to completely drain out of the tank.
