A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures to prevent scalding. The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static mixing valve, provides increased safety ...
Mis-assembly of some single-valve mixer taps will exchange hot and cold even if the fixture has been plumbed correctly. In the United States, the Americans with Disabilities Act provide requirements for faucets, such as requiring less than five pounds of force to operate, and requiring that the user does not have to twist their wrist.

A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze ...
Each fixture usually has a characteristic means of connection. Normal plumbing practice is to install a valve on each water supply line before the fixture, and this is most commonly termed a stop or "service valve". The water supply to some fixtures is cold water only (such as water closets and urinals). Most fixtures also have a hot water supply.
Some may require a screwdriver to remove; others can be popped or pried off. Step 2: Cover the drain opening with a damp rag. Place the hose against the rag-covered drain and turn on the shop ...
Maintaining constant shower temperature: Similarly, unlike with a tank heater, the hot water temperature from a non-modulated tankless heater is inversely proportional to the rate of the water flow—the faster the flow, the less time the water spends in the heating element being heated. Mixing hot and cold water to the "right" temperature from ...
A common use of the term "air gap" in domestic plumbing refers to a specialized fixture that provides backflow prevention for an installed dishwasher. This "air gap" is visible above the sink as a small cylindrical fixture mounted near the faucet. In the base cabinet under the sink, the drain hose from the dishwasher feeds the "top" of the air ...
The average U.S. household spends about $1,900 a year on energy costs, according to the U.S. Department of Energy. And the DOE says that anywhere from 5% to 10% of your residential electricity is ...
