How to Fix a Leaky Toilet

Is your toilet running long after you’ve hit the flush handle?  Even jiggling the handle is a short-term fix.  Fear not, in this video Lou shows you how to diagnose the problem and correct it properly.

Understanding how your toilet functions is a key element to figuring out how to prevent it from being a leaky toilet.  Basically, your central water supply feeds the tank through a hose, which is connected to a fill valve.  This fills the tank with water after you flush it (obviously).  There’s another valve inside the tank which is the likely culprit to your leaky toilet and that’s the flush valve.

Flush valves are connected to the actual flush handle via a chain (there are various different types out there so be sure to study yours so you know what style you have) and control a rubber flapper that lifts up and down to tell the toilet to flush the water in the bowl.  Because it’s made of rubber over time it will wear down and lose the ability to create suction when closed, which causes water to leak out of the tank and keeps your water running to constantly refill it.

Another cause could actually be the fill valve, whether the water level is set too high or there’s an actual defect inside the valve itself that is causing the water to continue running.

It’s best to start with the flush valve since replacing the rubber flapper is relatively cheap and easy to do.  If that doesn’t work, you can determine if the entire flush valve needs replacing or if the fill valve does.  Just be sure to turn off the water to the toilet before you start and be sure to empty the tank.

The replacement parts will come with installation instructions so be sure to follow those to ensure a successful outcome.
