What it is
The Monsoon S4.5 Bar Single is a pressure booster pump manufactured by Stuart Turner and part of the Monsoon range. It is a single pump unit rated at 4.5 bar, used to raise water pressure on domestic hot and cold supply systems where gravity or mains pressure is insufficient. The pump is installed on the pipework serving the outlets that require a boosted supply.
Signs this part needs replacing
- The pump runs but delivers little or no increase in outlet pressure.
- Motor fails to start when a tap or outlet is opened.
- Excessive noise, rattling or vibration from the pump body during operation.
- Water weeping from the pump casing, connections or seals.
- Repeated tripping of the electrical supply or intermittent running.
Before you order
- Confirm the existing pump is a Monsoon S4.5 Bar Single and that the 4.5 bar rating suits the installation.
- Check whether the system is served by a single pump or a twin pump arrangement.
- Verify available space and pipework connections at the intended installation point.
- Check the electrical supply and any controls associated with the existing pump.
