Common Reasons a Toilet Won't Stop Running
A running toilet is more than an irritation.
A running toilet is more than an irritation. When the water is continuously running, homeowners could waste gallons of water, resulting in much higher water bills.
Let's discuss some of the common causes of a running toilet:
A malfunctioning refill tube
One of the most common reasons for a continuously running toilet is a malfunctioning refill tube. The refill tube is a plastic tube connected to the top of the ballock on one end and the inside of the overflow tube on the other. Water runs through this tube during the flush cycle, replenishing the toilet's water bowl.
If the refill tube is damaged or sits below the water level, it may cause the water to run constantly.
Float ball issues
The float ball is a ball that sinks and opens the inlet valve on the fill tube when someone flushes the toilet. When the tank fills up, this small ball rises and shuts the inlet valve.
A malfunctioning float ball can also cause a running toilet. Namely, a misaligned float ball can't shut the inlet valve properly, so the filling process never stops, causing the water to run continuously.
Wrong flush valve chain
The flush valve chain opens the flush valve to allow fresh water to get into the tank when the toilet is flushed. In some cases, the chain can malfunction and cause the water to run. The first step is checking whether the chain is connected. Next, it's essential to check whether there's too little or too much slack in the chain.
Namely, if the flush valve chain is too short or too long, it may prevent it from closing correctly.
Worn gasket
The toilet gasket is a seal between the toilet bowl and the tank. When this gasket is damaged or worn out, water can run into the bowl continuously.
The toilet handle is stuck
A jammed toilet handle is one of the most common and easiest to resolve causes of a running toilet. Homeowners can fix it by pulling the lever attached to the toilet tank a few times to release the handle. If that doesn't work, the toilet handle may need replacement.
Water pressure may be too high
Besides faulty or damaged toilet and tank components, water pressure can also be the culprit for a running toilet. High water pressure combined with a fill valve that doesn't close all the way (typical for older homes) could result in a running toilet.
In such cases, homeowners may need to install a toilet pressure-reducing valve.
