More information

The Monsoon Standard Single Shower Pump is designed specifically for homes with vented water systems, where water is stored in a cold water tank and hot water cylinder rather than supplied directly from the mains.

Single pumps are ideal where only one water supply requires boosting, for example, improving hot water flow to a shower or outlet while maintaining the existing cold supply. This makes them a practical solution for targeted pressure improvements within the home.

This model is not suitable for unvented or mains-pressure systems, where water pressure is already supplied directly from the mains. If you’re unsure which system you have, our Monsoon range includes alternative options designed to suit different household setups and pressure requirements.
