Ask a Plumber: Why Won’t My Toilet Stop Running?

Toilet problems can be incredibly disruptive. As one of the most used appliances in your home, you need to make sure that it operates well every day throughout the year. One of the most common problems that we come across is toilets that continue to run long after flushing. While this may seem like an inconsequential, minor issue, it can actually lead to leaks and higher utility bills. There’s no repair too minor (or too large) for a professional Orlando plumber, so call Modern Plumbing Industries, Inc. (MPI) today.

Ask an Orlando Plumber: Why Won't my Toilet Stop Running?In order to better understand what the problem is with your toilet and why it won’t stop running, it’s useful to first look at how your toilet functions. Your toilet is comprised of three major components: the flushing mechanism, bowl siphon, and the refill mechanism. Simply physical principles ensure that there is a consistent and constant level of water in your toilet at all times. Water conforms to a container or surface because of gravity and the curvature of the pipe behind the bowl allows the overflowing of the bowl by the tank to cause the toilet to flush. So long as the bowl is filled quickly with enough water to activate the siphon, your toilet will flush.

The tank behind the toilet bowl rapidly dumps several gallons of water into the siphon, which causes the bowl’s contents to overflow down the drainpipe. But in order to control the flow, your toilet tank has a flush valve that controls the flushing mechanism. The filler float, which looks like a ball connected to the end of a stick senses the level of water in the tank, and tells the filler valve to send water into the tank and the bowl after the flush is complete, so that the flush mechanism can be restored.

A sticky or damaged flush valve can cause a toilet to run constantly after flushing. It may also be a problem with the chain that connects the handle to that mechanism. Sometimes a jiggle on the handle will ensure that the tank fills back up, but you may need to replace the part to ensure that it doesn’t happen regularly.
