Diagnosing a Constantly Running Dual Flush Toiletīefore proceeding to fix a constantly running toilet, you will need to be sure whether the problem is with the fill valve or the toilet seal. The overflow tube is a large pipe in the middle of the tank that sends excess water back to the bowl to avoid overflowing. It will, therefore, continuously fill the tank with water and will need to be replaced. If the toilet float height is higher than recommended, the fill valve will continuously fill the tank with water as the excess water runs down to the bowl through the overflow tube.Īpart from the toilet float, the fill valve could also be defective in such a way that it’s not shutting even after the tank is full and the float has gone up to its normal position. The water level in the toilet tank should be about ½ inch below the overflow tube. As the tank fills with water, the float moves up gradually to its set height, where it will stop and the fill valve will shut. When you flush the toilet, the float moves to the bottom of the tank, and the fill valve, which until that moment was shut, opens and starts filling the tank. The float controls the opening and closing of the fill valve and also the water level in the toilet tank. In dual flush toilets, a float cup/cylinder is connected alongside the vertical body of the fill valve. It is connected from underneath the toilet tank to the water supply line, and its function is to fill the toilet tank after every flush.
