Water Pressure Booster Pump London

Do you actually need a booster pump?

Low pressure has several causes and only some of them are fixed by a pump. A partially closed or seized stopcock, an old lead or galvanised main that has silted up, a failed pressure reducing valve, a blocked filter on a combi or a leak on the underground supply all produce the same symptoms. We measure static and dynamic pressure and flow at the incoming main before recommending anything. If the supply is healthy and the problem is height or simultaneous demand, a booster pump is the correct solution.

• Static and dynamic pressure measured at the main
• Flow rate tested against the property demand
• Stopcocks, PRVs and filters checked first
• Old lead or galvanised mains identified

Boosting from the mains and water regulations

You cannot simply strap a large pump onto an incoming main. Water regulations limit direct boosting from the mains, so anything beyond a small pump normally draws from a break tank, which stores water and gives the pump a stable, protected supply while safeguarding the public main from backflow and negative pressure. We size the tank to the property, site it where it can be inspected and serviced, and install it with the correct air gap, overflow and isolation.

• WRAS-compliant break tank arrangements
• Correct air gap and backflow protection
• Tank sized to peak demand, not guesswork
• Accessible siting for inspection and cleaning

Choosing the right pump for the property

A single weak shower in a house with otherwise good pressure may only need a small inline pump. A four-storey townhouse with two bathrooms in simultaneous use needs a properly sized set with an accumulator. A flat at the top of a block usually cannot be solved in isolation and needs the landlord's communal booster investigating. We tell you honestly which category you are in, and we do not sell a large set where a small one will do.

Noise, energy use and living with a pump

Pumps are mechanical and they make noise, which matters when the plant is in a cupboard next to a bedroom. We mount pumps on anti-vibration feet, use flexible connectors to stop noise travelling through the pipework, and specify variable speed units where the pump would otherwise hammer on and off. A correctly charged accumulator does most of the work for small draw-offs, so the pump starts less often, runs quieter and lasts longer.

• Anti-vibration mounts and flexible connectors
• Variable speed options for quiet operation
• Accumulators sized to reduce start frequency
• Sensible siting away from bedrooms where possible
