Hot Water Repairs

Joel Hunter


The systems involved in heating hot water in your home are complex and can develop any number of problems that require repair. Unless you are qualified to do so, it’s unwise to perform hot water repairs on your own unless you have been trained to do so. Systems that heat water usually involve natural gas or electricity, so knowing how to properly deal with the heat source can mean the difference between proper repair and injury or even death, as well as causing damage to the system itself.

These are some of the most common problems that occur in contemporary hot water systems.

Hot Water Tank is Leaking

This is a repair that you cannot do yourself, but you can take steps to prevent further damage. if you have a gas system, turn off the gas and water cocks. If the system is electric, turn off the electricity at the switchboard before the inspection. Check to see where the water is coming from and call a qualified repairer.

No Hot Water Coming From the Tap

First, check other gas appliances in the house to see if they have a gas supply. If there is none, contact your gas supplier. Next, check your water heater to see if the pilot light is on. If not, follow the manufacturer’s instructions to relight it. If you can’t do so, it’s time for a professional to inspect it.

No Water at All From Hot Tap

Check to see if the problem is isolated to one tap or to your hot water in general, and then check the cold water tap. If only the hot water is affected, look for a leaking tank or damaged pipes.

Water Flowing From the Outlet Valve

It’s normal for water to expel from this valve on occasion, but the flow should not be frequent or constant. Lift the flush lever on the valve three to four times to clear possible obstacles. If this measure doesn’t work, the tank may have a leak. These valves have a limited service life and need to be replaced periodically.

Broken Solar Collector

Evacuated tubes or flat panel collectors for solar hot water systems can break. The latter is far more costly as replacement of the entire panel is usually required. Tubes may be replaced one at a time. No matter which you have, you’ll need to contact your solar system supplier.

The Tank Emits Strange Noises

Several factors can cause this, but the most common one is sediment build-up. Often a tank flush will fix the problem. This job is best done by a professional, however, if your owner’s manual has clear and safe instructions, you may be able to do it on your own.
