Filling Loops and Valves

A filling loop is a pipe that is used to connect the mains water supply to the central heating system. If the boiler pressure gets to low, a filling loop can be used to to pressurize the water in the central heating system. They are commonly used in the installation and servicing of boilers. They can also be used when a boiler needs draining or bleeding.
