# Pump Service & Installation

Pump Service & Installation (PSI) is a specialist water systems company based in Devizes, Wiltshire, serving private and supplementary water supply systems across Wiltshire and surrounding counties. The business focuses exclusively on the clean water side of operations—from water abstraction through to consumption—deliberately excluding waste, foul, and sewerage work to maintain rigorous hygiene standards and prevent cross-contamination.

PSI offers comprehensive support for pump and filtration equipment, working with leading manufacturers including Grundfos, Lowara, Calpeda, and DAB. The team handles everything from initial installations and commissioning through to ongoing servicing, fault diagnostics, and repairs, making them a one-stop solution for water supply system challenges.

What sets PSI apart is their unwavering commitment to three core principles: professional workmanship, safety, and efficiency. The business positions itself as "Personal, Experienced, and Certified," reflecting a hands-on approach rather than impersonal corporate service. Their specialist expertise in private water systems demonstrates genuine knowledge within a niche sector, reassuring clients that they're working with technicians who understand the specific complexities of their installations.

By maintaining clear boundaries around their service scope and refusing to undertake incompatible works, PSI demonstrates integrity and quality focus. This specialisation, combined with their established relationships with major pump manufacturers and their service coverage across multiple counties, makes them a reliable choice for property owners and businesses reliant on private water systems.
