FAQs
What is a boosted cold-water mains system and why might my Bristol commercial property need one?
A boosted cold-water mains system consists of a storage tank (break tank) and one or more pressure pumps that deliver water to your building at a constant, higher pressure than the incoming mains. Many Bristol businesses—especially those in multi-storey offices, hotels, healthcare facilities and leisure centres—experience low mains pressure at peak times. A booster set ensures every outlet (taps, WCs, showers, process equipment) receives adequate flow and pressure, improving hygiene, user comfort and appliance performance while meeting Building Regulations.
How do you determine the correct size and specification of the booster set for my building?
We carry out a detailed site survey that measures your existing mains pressure and flow, the number of storeys, peak occupancy, fixture unit count, and any special demands such as irrigation or process water. Using British Standard BS EN 806 calculations and our in-house sizing software, we select the optimum break-tank capacity, pump duty (flow & head) and control methodology (inverter-driven, fixed-speed or variable-speed). This ensures the system meets peak demand without oversizing, saving energy and prolonging pump life.
Will installing a booster pump affect my compliance with water regulations in Bristol?
No—provided the installation is designed and installed correctly. We use only WRAS-approved break tanks, non-return/backflow prevention valves and potable-water-grade materials. Our engineers follow the Water Supply (Water Fittings) Regulations 1999, BS EN 806 and BS 8558 guidelines. We also notify Bristol Water where required and provide certification on completion, keeping you fully compliant with local water authority requirements.
How disruptive is the installation process, and will my business experience downtime?
Most commercial booster installations can be completed with minimal disruption. We prefabricate much of the pipework off-site, schedule works outside trading hours when possible and maintain temporary water supplies so essential services remain operational. A typical retrofit in an existing plant room takes 1–3 days, while new-build installations are coordinated with your main contractor’s programme. We provide a detailed method statement and agree a phased shut-off schedule in advance to keep downtime to an absolute minimum.
What ongoing maintenance does a boosted cold-water system require, and do you offer service contracts?
To keep pumps efficient and water quality safe, we recommend quarterly or bi-annual servicing. This includes checking pressure vessels, cleaning level sensors, testing non-return valves, inspecting electrical connections, verifying pump duty, and disinfecting the break tank if needed. We offer tailored service contracts with 24/7 emergency call-out across Bristol, full asset logs, and predictive maintenance alerts to prevent unexpected failures.
How much does a commercial boosted cold-water mains installation cost in Bristol and what factors influence the price?
Budget figures range from £4,000–£12,000+ depending on system size. Key cost drivers include: required pump duty (kW and flow rate), break-tank capacity, control type (inverter vs. fixed-speed), pipe material (copper, stainless, or MDPE), space constraints (plinths, acoustic enclosures), electrical upgrades, and whether we need out-of-hours work. After a free survey we provide a fixed quotation that details equipment, labour, commissioning, certification and optional maintenance plan so you have full cost transparency.
