Toilet Energy Efficiency
Running toilets are a common problem in all homes. The sound is irritating but even more is the added costs from wasted energy. Even a slow leak can add up to large amounts of wasted water quickly. To make matters worse, a lot of leaks go undetected in homes because the water flow is very small.
Toilet Leak Test
Some leaks are obvious because of the volume of water flowing. In these cases there is no need to run this test. Go to the next section and look for the correction action to fix the problem. If the water supply won’t shut off you should hear it with the tank lid removed. Lift the ballcock up to see if this is the problem. If the water stops you know you’ve found the culprit.
If you still are unsure, find some food coloring. A red or blue color works best since it is easy to see. Before you go to bed place several drops in the water tank. In the morning look in the bowl to see if any color is present. Coloring present in the bowl indicates a leaky flapper.
Fixing Running Toilets
The two most common sources of a running toilet are the flapper or floating ballcock. The ballcock is the floating ball or assembly in the toilet’s water tank that indicates when the water supply should shut off. The water will keep running if the ballcock is set too high. Simply adjust the float down to shut off before the water reaches the overflow tube.
The flapper is responsible for most sneaky leaks. Over time it warps and doesn’t seal as well. Water pressure from the tank creates a slow leak in any of the tiny gaps. The good news is a new flapper costs only a couple bucks and is easy to fix.
