VerticalBoosters Sets

Sizing comes down to two figures: the flow rate (litres per minute) you need at peak demand, and the additional head (pressure) required to overcome height and pipe losses. For a house this might mean checking the number of outlets likely to run simultaneously; for a commercial building you'd calculate based on occupancy and fixture count. If you're unsure, give us your incoming supply pressure, required outlet pressure and peak flow and we can help match a set.

Yes — smaller vertical booster sets are commonly fitted in homes with low mains pressure, multi-storey properties, or where several bathrooms need to run together without pressure drop. They're generally more compact and quieter than horizontal alternatives, which suits domestic plant rooms or cupboards. Larger multi-pump sets are aimed more at commercial and industrial applications.

This depends on your water company's regulations and the set's design — many UK water suppliers don't permit direct mains boosting above a certain flow rate to protect pressure for neighbouring properties. In these cases a break tank is required to provide an air gap before the booster draws from it. Always check with your local water authority before specifying a direct-connect system.

Routine checks should cover pressure vessel charge, seal condition, and controller/sensor operation, typically every six to twelve months depending on usage. Multi-pump sets with duty/standby or duty-assist configurations should have each pump run periodically to ensure even wear. Most sets include diagnostic displays that flag faults early, reducing unplanned downtime.

Multi-pump sets (typically two or three pumps) provide built-in redundancy — if one pump fails or needs servicing, the others maintain supply. They also allow the control system to stage pumps on and off to match demand more precisely, which improves energy efficiency compared with a single oversized pump running constantly. This makes them well suited to commercial buildings where continuous water supply is critical.

Vertical booster sets are heavier and bulkier than a standard pump, so check access to the plant room or intended location, including doorways and any lifting requirements, before ordering. Delivery lead times vary by model and specification, particularly for larger commercial sets built to order. Installation should be carried out by a competent plumber or engineer, with electrical connections completed by a qualified electrician in line with wiring regulations.
