Cold Water Storage Tank Repair

What cold water storage tank repair covers

If your cold water storage tank is leaking, overflowing, or not delivering steady pressure, the issue is often a failed or worn component rather than the tank itself. Repairs are targeted, practical, and aimed at restoring normal operation with minimal disruption.

Typical work includes:

• Diagnosing the fault and checking connected pipework and fittings
• Isolating the supply and draining down where required
• Repairing leaks on outlets, connections, and pipe joints
• Replacing faulty valves (such as float operated valves) and sealing washers
• Addressing problems with overflows and constant running
• Fitting or securing tank lids to reduce contamination risk
• Testing for correct refill, shut-off, and flow after the repair

When this service is the right fit

This service is a good match if you have a cold water storage tank in the loft or airing cupboard and you have noticed one of the following:

• Water marks on ceilings or damp around the tank area
• A tank that keeps refilling, overflows, or makes persistent noise
• Reduced cold water flow at taps fed from the tank
• A loose, damaged, or missing lid, or signs of debris in the water

If the tank body is split, badly corroded, or undersized, a replacement may be more sensible. You will be advised clearly once the system has been assessed.

What happens during the repair visit

The repair starts with a quick set of checks to confirm the tank type, how it is fed, and what outlets it supplies. The water supply is then isolated and, if needed, the tank is partially drained so components can be worked on safely.

Once repaired, the system is refilled and tested. You should expect a clear explanation of what failed, what was changed, and what to watch for next.

Aftercare and preventing repeat issues

After testing, you will be told if any follow-up work would reduce the risk of future problems, such as improving access to the tank, correcting an overflow route, or replacing aging fittings before they fail. If water hygiene is a concern, you can also discuss options such as a better fitting lid or addressing contamination risks around the tank area.
