Common Questions — Hot Water Cylinder in Harrow

My hot water cylinder is leaking in Harrow. What should I do?

Turn off the cold feed to the cylinder (usually a gate valve or ball valve on the inlet pipe) and turn off the immersion heater or boiler. Call us immediately — a leaking cylinder in a Harrow property can cause significant structural damage if left running.

How long does a hot water cylinder last in Harrow?

In London's hard water areas — including most of Harrow — a copper cylinder typically lasts 15–25 years. Scale build-up and corrosion are the main causes of failure. If the cylinder is over 20 years old and showing signs of corrosion, replacement is usually more cost-effective than repair.

Can you replace my hot water cylinder in one day in Harrow?

Yes. A like-for-like cylinder replacement in a Harrow property is usually completed in one day. We drain down, remove the old cylinder, fit the new one, connect all pipework, and commission with a full pressure test before leaving.
