How do I know if my hot water cylinder is leaking?

Signs of a leaking hot water cylinder include:

• Water pooling around the base of the cylinder.
• Damp walls, flooring, or cupboards near the cylinder.
• A constant dripping from the relief valve.
• Rust stains or corrosion on the cylinder.
• Your hot water running out more quickly than usual.

If you notice any of these signs, it’s important to have the cylinder inspected before the leak worsens.

Why is my hot water cylinder leaking?

Leaks can be caused by:

• A corroded or rusted cylinder.
• A faulty temperature and pressure relief (TPR) valve.
• Loose or damaged pipe fittings.
• Excessive water pressure.
• Internal cylinder failure due to age.

Our plumbers will identify the cause and recommend the most cost-effective solution.

Can a leaking hot water cylinder be repaired?

Yes, in many cases. If the leak is coming from a valve, fitting, or pipework, it can often be repaired. However, if the cylinder itself has rusted through or has an internal failure, replacement is usually the safest and most economical option.

How urgent is a leaking hot water cylinder?

Very. Even a small leak can cause water damage to flooring, walls, and cabinetry. If the leak becomes severe, it can also leave you without hot water. We recommend arranging repairs as soon as possible.

What should I do if my hot water cylinder is leaking?

If it’s safe to do so:

• Turn off the electricity or gas supply to the cylinder.
• Shut off the cold water supply to the cylinder.
• Contact us to arrange an inspection and repair.

If the leak is significant, avoid using the hot water system until it has been assessed.

How long does a hot water cylinder repair take?

Most valve and pipework repairs can be completed within a few hours. If the cylinder needs replacing, installation is usually completed the same day.

How long should a hot water cylinder last?

Most quality hot water cylinders last between 10 and 20 years, depending on water quality, maintenance, and the type of cylinder. If yours is approaching the end of its lifespan, replacement may be the most reliable option.

Should I repair or replace my hot water cylinder?

A repair is usually worthwhile if the problem is a faulty valve, fitting, or pipe. If the cylinder is leaking from the tank itself, heavily corroded, or has failed due to age, replacement is generally the better long-term investment.
