Why is a pressure reducer needed?
Mains water or booster pump pressure can be higher than required in some buildings, especially on lower floors. Excessive pressure strains the seals and components of faucets, mixers, toilet cisterns, washing machines, dishwashers, combi boilers, and electric water heaters. It also causes noise, water hammer, and unnecessary water consumption. A pressure reducer (pressure regulator) keeps the outlet pressure at a set value regardless of the inlet pressure, protecting the entire installation.
Category contents
- Pressure reducers with pressure gauge: Allow the outlet pressure to be monitored via the built-in pressure gauge.
- Adjustable models: The outlet pressure can be set using an adjustment screw or knob.
- Union-connection models: Simplify installation and removal.
- Various connection sizes: Sizes such as 1/2 and 3/4 inch suit residential and small commercial installations.
The category includes models from Caleffi, Honeywell, Welko, and Pakkens.
Where and how is it installed?
A pressure reducer is generally installed at the building or apartment inlet, after the water meter, so that the entire installation is protected. It can also be installed at the inlet of a specific appliance to protect only that device. During installation, attention must be paid to the flow arrow on the body, and a Y-strainer should be fitted upstream; many models also include an internal strainer. It is recommended to install isolating valves before and after the pressure reducer for maintenance purposes. The outlet pressure should be set according to the values recommended by the manufacturers of the connected appliances.
Maintenance
The internal strainer can become clogged with sand and sediment over time, reducing flow rate; regular cleaning is required. If the outlet pressure is found to rise together with the inlet pressure, the regulator's internal components may be worn, in which case a repair kit or replacement is needed.
Frequently asked questions
What value should the pressure reducer be set to?
It should be set according to the recommended operating pressures of the appliances in your installation; check the pressure gauge during adjustment.
Does a pressure reducer reduce flow rate?
A correctly sized regulator does not cause noticeable flow loss in use; however, a clogged strainer will reduce flow rate.
Can it be used instead of a safety valve?
No; a safety valve is a separate safety device and is required on hot water appliances.
Can it be fitted at the booster pump outlet?
Yes; it can be installed at floor inlets in situations where the booster pump pressure remains too high for certain floors.
What is the advantage of a model with a pressure gauge?
Lets you continuously monitor the outlet pressure, making adjustment and fault detection easier.
What does a noisy pressure reducing valve mean?
Excessive pressure differential, dirt, or wear on internal parts can cause noise; clean the strainer and check the setting.
