Adjusting the water level in a toilet is a simple plumbing task that can help to improve the efficiency of your toilet and prevent costly repairs. An optimal water level ensures a proper flush, prevents leaks, and conserves water.
Toilets have a fill valve that controls the water level in the tank. Over time, the fill valve can become worn or damaged, causing the water level to be too high or too low. If the water level is too high, it can cause the toilet to run constantly, wasting water and increasing your water bill. If the water level is too low, the toilet may not flush properly, leaving waste behind.
