FAQs
How often should I have my Gledhill cylinder inspected?
It is recommended to have your cylinder inspected annually by a qualified professional.
What is the purpose of the expansion vessel?
The expansion vessel accommodates the expansion of water as it heats, preventing excessive pressure build-up.
Can I install the cylinder myself?
No, installation *must* be performed by a qualified professional to comply with safety regulations and ensure proper function.
How do I know if my cylinder needs descaling?
Signs of scale build-up include reduced hot water flow, noisy operation, and increased energy consumption. Your installer can advise.
What should I do if the water temperature is too low?
Check the thermostat setting and ensure it is set to the desired temperature. If the issue persists, contact a qualified engineer.
How do I test the pressure relief valve?
Carefully lift the lever on the pressure relief valve. Water should flow out. If it doesn't, or if the valve is constantly dripping, have it inspected by a professional.
What type of fittings are included with the cylinder?
The cylinder comes complete with compression fittings, a lift-up P&T valve, a 90-degree elbow on the hot water draw-off, and a flexible hose for the expansion vessel.
Troubleshooting
Low water pressure.
Check the mains water supply and ensure the incoming water pressure is adequate. Also, check for any blockages in the hot water outlets or the cylinder itself.
No hot water.
Check the electrical supply to the immersion heaters (if applicable). Inspect the thermostat and ensure it is set to the correct temperature. If the cylinder is gas heated, check the gas supply and the boiler.
Water leaking from the pressure relief valve.
This could indicate a problem with the expansion vessel or the water pressure. Consult a qualified engineer to inspect and rectify the issue.
