Domestic Hot Water Cylinder Repair

A properly functioning hot water cylinder is essential to ensure a constant supply of hot water in your home. Whether it’s for showering, doing the dishes or washing clothes, a faulty cylinder can be a major inconvenience. Over time, hot water storage tanks can develop leaks, inefficiencies or heating problems that require repair. Knowing the most common problems, signs of failure and repair solutions can help homeowners maintain an efficient water heating system.

Common Hot Water Storage Tank Problems

Hot water storage tanks can experience a variety of problems due to wear and tear or improper maintenance. Some of the most common problems are:

Leaks: One of the most common problems, leaks can occur due to corrosion, damaged valves or loose connections. Even minor leaks should be addressed promptly to prevent further damage.
Lack of hot water: Lack of hot water can be due to a faulty thermostat, a broken heating element or problems with the electrical supply.
Insufficient heating: If the water does not heat to the desired temperature, it could be due to sediment buildup, a malfunctioning thermostat or an aging heating element.
Strange noises: Rumbling, banging or hissing sounds from the cylinder usually indicate sediment buildup or air trapped in the system.

Steps for repairing a hot water cylinder

The repair of a hot water cylinder depends on the specific problem. Below are some steps to solve the most common problems:
Inspect for leaks: check for visible leaks in the accumulator, valves and connections. Tightening loose fittings or replacing damaged washers may fix minor leaks, but major leaks may require professional help.
Check the thermostat: If the water is not heating properly, check the thermostat settings. Sometimes resetting or replacing a faulty thermostat can solve the problem.
Flush the cylinder: Sediment buildup can reduce efficiency and cause strange noises. Emptying and flushing the tank periodically helps remove sediment and improves performance.
Replace the heating element: If the cylinder won’t heat water at all, a burned-out heating element may be the culprit. Replacing it with a new one can restore proper operation.
Check the pressure relief valve: Malfunctioning pressure relief valve can cause leaks or pressure problems. Checking and replacing it when necessary ensures safe operation.
