What's in a service
- Full inspection of the cylinder and controls
- Expansion vessel pressure check and recharge
- Safety valve (T&P and expansion relief) checks
- Immersion heater and thermostat checks
- Efficiency optimisation
Prevention beats repair
Most safety valve failures are actually caused by expansion vessels losing pressure over time. Regular servicing identifies these issues before they become expensive repairs — and keeps the system running the way the manufacturer intended.
Good to know
Why does an unvented cylinder need an annual service?
Expansion vessels lose their air charge over time, which makes the safety valves operate repeatedly and eventually fail. An annual service catches this early — before it becomes a more expensive repair or wastes water.
Do you service cylinders for landlords and managing agents?
Yes — we look after systems for apartment owners, landlords and managing agents across Manchester and Salford, including block-wide servicing arrangements.
