How to Maintain a Dual-Flush Toilet

Extend the life of your dual-flush toilet with the proper maintenance.

Dual-flush toilets are designed to help conservation-minded people limit their water use. Popular in Japan and catching on in the United States, these toilets differ from normal toilets because they provide the option to either use a half flush (for liquid waste) or a full flush (for solids) after use. Like regular toilets, dual-flush toilets are not a high-maintenance item. However, they do require some care to remain functional and to work properly.

Instructions

1. Check that the toilet is properly installed. Ensure the base of the toilet is solidly attached to the floor.

2. Try to move the toilet. If it slides, rocks or twists, it is not properly installed. Check for any leaks. Your toilet should be completely leak-free.

3. Clean the toilet on a regular basis to prevent degradation from bacteria buildup. Avoid using drop-in cleaners in the tank, because they can damage the rubber flapper and cause leaks. Discard a cleaning brush after it has worn down, because the metal beneath the bristles can damage your bowl.

4. Maintain a constant water line in the tank at all times. If you notice your toilet flush getting weaker, adjust the water supply line slightly to let more water into the tank.

5. Check the seals on the flush ball periodically. If your toilet flushes on its own sometimes or runs when not used, you may need to replace the flush ball.

6. Cut down the water supply slightly if the tank is loud when refilling. Reducing the water pressure should stop the noise.
