Why is my toilet constantly running?

A running toilet can be one of the most annoying things that a homeowner has to deal with. Not only does the noise cause quite the distraction, but if not taken care of properly, it can result in an expensive water bill. Basically, a running toilet is an internal water leak, so to fix it, you’ll have to examine the inside of the toilet tank. Here are some reasons why your toilet might be constantly running.

Reason 1: Leaky Pipes

The most common cause of a running toilet is a leaky pipe inside the toilet. Toilet manufacturers are notorious for not thoroughly testing their products, due to numerous issues. The material used is often sub-standard, and it may have been packed with unsafe chemicals and used in areas that are extremely hot. These factors combined can cause pipes to break, resulting in a leaky toilet. If you are unsure as to whether or not your toilet can be repaired, take it out and have a professional look at it.

Reason 2: Toilet Parts not Working Properly

Another common cause of a running toilet is one of the toilet parts around the water fill valve. The fill valve has small internal parts that can break or rust. In most cases, these parts are plastic and cannot withstand much force. This is the reason a toilet can run constantly. Crappy parts cause water to leak, which causes the water to always flow into the toilet tank. The first thing that should be done if you hear your toilet constantly running is replacing any broken parts with better-quality ones.

Reason 3: Connections Back to the Water Valve Are Loose

Another common reason for a running toilet is bad connections between the water valve and the rest of the plumbing system. Most toilets have an internal tank that contains a float valve and float ball assembly. Depending on the type of toilet, there may be more than one piece of plumbing in this assembly. If anything goes wrong with these parts, water continuously flows into the tank. The fix for this problem is a water shutoff valve. These valves are usually found around the water under the sink and are easily accessible. They are small silver boxes that should not be tampered with under any circumstances.

Reason 4: Leaky Valve Seat

The valve seat can also be a common source of leaks within toilets. This is the large rubber ring where the toilet valve screws in. The seal that this part provides can be worn down over time, especially if you encounter hard water. Water leaks near the bottom of the toilet tank may be caused by a leaky valve seat. To get rid of this issue, you should replace it with a better quality one to ensure that it will not wear out again.

Reason 5: Leaky Manifold

The manifold that is around the tank of a toilet can be another source of leaks. This part is basically a tube that connects the water valve to the rest of the piping and can also contain various parts such as flapper valves. If this part leaks, it may cause quite a mess. There are several ways to get rid of this problem by replacing old parts or getting new ones altogether.

So there you have it. Some common reasons why a toilet could be running continuously. The first thing that should be done is to replace any parts that are worn out, damaged, or broken from old age. Additionally, replace any parts around the water fill valve if they are made of metal and corroded. Lastly, check the connections between your toilet and the rest of your plumbing system for leaks before looking at other more expensive parts.
