Pumps and mechanical systems
Specialist maintenance and repair of pumps, pressurisation units and associated mechanical plant, for optimal performance and longevity.
The challenge
Pumps keep the whole building running
Circulation pumps, booster sets and pressurisation units move heating and water around the building. When one fails, residents can lose heating, hot water or water pressure, often with little warning.
Our engineers are trained on all major manufacturers, so whether it is a secondary circulator or a booster set, we keep your system running at peak performance.
