Low-pressure faucet

A low-pressure faucet is a special type of faucet designed exclusively for connection with a non-pressurized water heater, which are usually small electric boilers placed under a sink or washbasin. Unlike a standard, so-called "high-pressure" faucet, a low-pressure faucet has three connection hoses instead of two. One brings cold water from the water main, the second carries cold water from the faucet to the heater, and the third brings heated water from the heater back to the faucet. When you turn on the hot water, the faucet first opens the cold water supply to the heater. This cold water displaces the already heated water from the heater out through the faucet. Thus, the heater itself is never exposed to the full pressure of the water main. During heating, the water in the boiler expands and increases its volume. To prevent damage to the heater, the excess water must drip from the faucet spout. This dripping is therefore not a defect, but a correct and necessary function of the entire system. Using a conventional high-pressure faucet would lead to the destruction of the non-pressurized heater.
