A constantly running toilet can waste a lot of water and increase your utility bills, but fixing it is often simpler than you might think. The most common cause is a malfunction within the tank, which affects how the flushing mechanism works. To start, you should check the valve and consider a valve replacement if it’s faulty. The fill valve controls the water level in the tank, and if it’s not functioning properly, the water keeps running. First, turn off the water supply to the toilet, usually by twisting the valve located behind the tank. Flush the toilet to drain most of the water, then remove the lid from the tank. Inspect the fill valve for signs of damage or wear. If it looks old or corroded, replacing it can resolve the issue. You can find replacement fill valves at any hardware store, and they usually come with instructions. Installing a new valve often involves disconnecting the old one, attaching the new valve in its place, and adjusting the height to ensure the water level stops at the correct mark. Once installed, turn the water back on, and check if the tank fills to the proper level without continuously running.
Another common cause of a running toilet is debris or mineral buildup inside the tank, which can interfere with parts like the flapper or float. Performing tank cleaning can often fix these issues. Turn off the water supply and drain the tank by flushing. Remove any buildup on the flapper, which is the rubber seal at the bottom of the tank that controls water flow into the bowl. If the flapper is damaged or warped, replacing it is a quick fix. While you’re in there, clean the inside of the tank, removing sediment or mineral deposits that could be affecting the functioning of the fill valve and other components. Use a brush and some mild cleaning solution or vinegar to scrub away buildup. After cleaning, reassemble everything, turn the water supply back on, and observe the tank filling and flushing. If the toilet continues to run despite these efforts, you might need to adjust the float or replace other internal parts.
Regular maintenance, including inspecting the toilet components, can prevent future problems and improve efficiency. Addressing these common issues—valve replacement and tank cleaning—can restore your toilet’s proper function and save you money on water bills. Most repairs are straightforward, and with a few basic tools and some patience, you can fix a running toilet yourself without needing a plumber.
