Low mains water pressure?

The WaterBoost WB-Compact 3.0 bar booster pump is designed to deliver increased water pressure to your building’s supply of up to 3.0 bar. The pump reacts to low water pressure, automatically increasing when mains water pressure falls below the pump’s pre-set value.

Capable of boosting incoming mains water to the entire house at a flow rate of up to 12 litres per minute, the WB-Compact 3.0 inline pump is an excellent solution for enhancing water performance. It is ideal for unvented hot water cylinders, combination boilers, electric showers, and mixer showers.

A full-bore bypass can be installed for uninterrupted water supply during pump maintenance. Additionally, the WB-Compact 3.0 pump complies with water authority regulations, ensuring the flow rate remains within the 12 litres per minute limit.

The WB-Compact 3.0 pump also features WiFi connectivity and can be remotely controlled via the DConnect app. With voice commands like “Hey Google, power shower,” the pump increases pressure, or “Hey Google, sleep mode” to switch it off at night, you can enjoy smart, convenient water pressure management.

The pump has 3/4″ Male BSP connections. Both in straight and right angle connections.

Additional Information

Low Water Pressure

Water pressure can vary throughout the day, typically dropping during the morning and evening when demand is highest as more people use water at home.

Pressure is measured in bars, with 1 bar of pressure capable of pushing water to a height of 10 metres within your home. The legal minimum water pressure required at your boundary stop tap is 7 metres head (0.7 bar). However, the WaterBoost WB-Compact 3.0 mains booster pump can significantly increase this, boosting pressure up to 3.0 bar!

If you’re not on a shared supply, your neighbours should experience similar water pressure to yours, provided your homes are of similar height and located at the same distance from the water main. However, water flow can vary individually between properties.

It’s important to distinguish between low water pressure and low water flow. You may have high pressure but still experience a low flow rate, often due to limitations in your private supply pipe. In such cases, an accumulator may be a more effective solution than a booster pump.
