	A pressure reducing valve (PRV) functions, as the name suggests, by reducing a high inlet pressure at the inlet to a safer, lower water pressure at the outlet. The benefits of PRVs are multiple, as lower water pressures can decrease the amount of damage to heating systems, appliances, and buildings. Considering water pressure in the UK can vary from 1 bar to 20 bar, it is important that any risk to plumbing and heating systems is minimised to keep buildings and people safe.

A pressure reducing valve (PRV) functions, as the name suggests, by reducing a high inlet pressure at the inlet to a safer, lower water pressure at the outlet. The benefits of PRVs are multiple, as lower water pressures can decrease the amount of damage to heating systems, appliances, and buildings. Considering water pressure in the UK can vary from 1 bar to 20 bar, it is important that any risk to plumbing and heating systems is minimised to keep buildings and people safe.

As there are no regulations on water pressure in the UK there are no regulations for specifying PRVs, however, to reduce risk of unsafe water pressure it is highly recommended to specify them not only for domestic buildings, but especially for commercial buildings, where it is not uncommon to have sudden jumps in water pressure. PRVs ensure that the flow rate of water is not only correct for its intended purpose but that there is a safe water pressure that will allow other valves, such as thermostatic mixing valves, to function correctly as well. The individual valve that should be specified will depend heavily on the type of building, the water flow rate, and whether or not it is being used on a hot or cold-water supply.
