Low Water Pressure at Home: How to Size a Booster Pump Properly

Before adding a booster pump, work out whether the municipal supply itself is low, whether only one outlet is weak because of a local blockage, or whether pressure only drops when several outlets run at the same time. Size the flow for the outlets that are realistically used together, and size the head for the height difference to the highest outlet plus pipe losses and the outlet pressure you want to keep — more head is not always better. On-off pumps with a pressure tank suit smaller homes, while variable-speed constant-pressure pumps give steadier temperature and lower noise when several people use water at once. Pipework and wiring must be installed by qualified personnel.
