Saniflo's Saniboost Smart booster pump has been picked up as a fix for a low water pressure problem in a Dublin property, according to Professional Builder — a useful data point on a pump that only recently joined the company's Clear Water range.
What the pump actually is
The Saniboost Smart is a variable-speed mains boosting pump, designed for the specific and very common scenario where the incoming mains supply is technically adequate but the delivered pressure and flow at the outlets are not — usually because of restrictive or undersized mains pipework, long runs, or a property sitting at the wrong end of a distribution network.
Published performance figures put it at up to 97 litres per minute of flow and up to 5.5 bar of pressure on mains-fed systems, with a maximum flow rate of 5.2 m³/h and a maximum head of 56m. Output pressure is adjustable from 1.5 to 5.5 bar, so it can be dialled in for the property rather than run flat out.
Two features matter for an installer:
- Variable speed. The pump modulates to demand rather than cycling hard on and off, which is what makes the difference between a shower that holds a steady pressure and one that surges when a tap opens elsewhere.
- Dry-run protection with auto-start. It shuts down when no water is detected and restarts when supply returns. On a mains-fed boost that is the failure mode you actually need protecting against — a supply interruption running the pump dry.
Quoted noise is under 50 dB(A), which is relevant because these units frequently end up in utility rooms, under stairs or in airing cupboards adjacent to living space.
Where it fits for UK plumbers
The classic UK use cases are much the same as the Dublin one: a converted flat with a long horizontal run off a shared riser, a rural property on a weak mains connection, or a retrofitted en-suite on an upper floor where the existing pressure won't drive a decent shower.
The important compliance check before specifying any mains booster in England and Wales is the Water Supply (Water Fittings) Regulations 1999 position on drawing directly from the mains — boosting the incoming supply beyond a certain flow rate requires either consent from the water undertaker or a break tank arrangement, and the limits vary by supplier. That is not a reason to avoid a boost pump; it is a reason to make the check part of the quote rather than a discovery on commissioning day.
Watch for: UK trade pricing and merchant availability, which the source piece did not carry, and whether Saniflo publishes typical noise and pressure data at the sort of part-load conditions installers actually run these at.
