Repair dripping faucets by replacing washers. If your faucet is dripping at the rate of one drop per second, you can expect to waste 2,700 gallons per year, which will add to the cost of water and sewer utilities, or strain your septic system. Check for toilet leaks by adding food coloring to the tank. If the toilet is is leaking, color will appear within 30 minutes. Check the toilet for worn out, corroded or bent parts.
Most replacement parts are inexpensive, readily available and easily installed.
Avoid flushing the toilet unnecessarily. Dispose of tissues, insects and other such waste in the trash. Install a toilet dam or displacement device such as a bag or bottle to cut down on the amount of water needed for each flushing. When purchasing new or replacement toilets, consider low-volume units which use less than half the water of older models. In many areas, low-volume units are required by law.
