Toilets

Toilet leak detection Leaky toilets can lose 200 gallons of water per day, so it’s important to check for leaks. Be observant and listen, and you may be able to hear the water moving from the tank to the bowl unrelated to flushing. An easy way to detect a leak is to deposit a few drops of liquid food dye into the tank; if the dye appears in the bowl of the toilet, the valve may be leaking or the flapper may not be seated correctly in the tank.
Ultra Low Flow (ULF) EPA WaterSense, LogoToilets that comply with the Arizona code standard of 1.6 gallons or less per flush are sometimes called ultra low flow (ULF) toilets. High-efficiency toilets (HETs) go beyond thestandard and use only 1.28 gpf, a 20% savings. A high-efficiency toilet can save 4,000gallons of water per year.

Dual Flush Toilet Domestic Plumbing, PhotoA dual flush toilet has two options for flushing: one that uses 0.8 to 1.2 gallons per flush for liquid waste and one that uses 1.6 gallons per-flush for solid waste. This "half flush" and "full flush" technology can reduce water usage by up to 67%.
Automatic flush control These toilets have a sensor that uses a beam of infrared light to activate flushing.
Tankless toilets and urinals In contrast to toilets that rely on a water tank and gravity to flush the contents, tankless toilets waste less water per flush. They employ a flushometer which is a device that releases a metered amount of water into the toilet, then closes back up. Toilets with flushometers are most commonly seen in public restrooms and places of business.
ULV and High Efficiency Urinals High efficiency urinals comply with the Arizona code standard of less than 1 gallon of water per flush. Ultra low volume urinals, sometimes called “wash-down urinals”, use between 0.5 and 1 gallon of water per flush. Depending on the brand or model, the flushing mechanism may be located on top of the fixture, on the wall above the fixture, or may be automatic.
Automatic Urinal Flush Control These urinals have a sensor that uses a beam of infrared light to activate flushing. The sensors identify when the urinal has been used (or when someone has stood in front of it and moved away), and activate the flush. The controls are designed to prevent activation by passers-by and to reset after use to accommodate the next person. There is no need for the user to contact an activating device which may be helpful to people with disabilities and also helps prevent the spread of disease. Retrofit kits are available for home use.
Waterless Urinals Waterless urinals use no water for flushing, although they do require a small amount for cleaning. A waterless urinal can save up to 45,000 gallons of water a year. Waterless urinals are typically found in large complexes such as ballparks, office buildings and airports. A cartridge and liquid sealant is used to prevent odors in the u bend. The cartridge must be cleaned with a small amount of water and periodically replaced.
