Common Water Heater Problems And Troubleshooting Tips

Whether you need to repair your water heater or replace it, there are a few things to look out for before you start. You will need to know about the Pressure relief valve, heating elements, and Anode rods.

Anode rods

Having an anode rod installed is a good way to extend the life of your water heater. Anode rods are typically made from magnesium or aluminum. Depending on the quality of the water, the anode rod may need to be replaced after three to five years. If you do not know how to replace an anode rod on your own, it may be best to call a plumber to do it for you.

You should check your anode rod on a regular basis to avoid leaks and corrosion. The lifespan of anode rods is based on the quality of the water and the type of anode rod used.

If you live in a hard water area, you may want to use an aluminum or magnesium anode. If your water is soft, you can opt for a zinc and aluminum blend. These anodes are less expensive and do not corrode as quickly as magnesium.

Anode rods should be removed from your water heater at least once a year. If you have a water softener, you should check your anode rod more frequently.

Heating elements

Among the most common problems with water heaters are broken heating elements. These components turn on and off in order to maintain the right temperature of the water in the tank. Having a bad element is not only a nuisance but also could cause serious internal damage.

A good way to find out if your element is faulty is to check with a multimeter. You can purchase a multimeter at your local hardware store. It is an inexpensive instrument that can be used to measure voltage, amperage, and other electrical conditions. You can use it to test your battery, as well as to diagnose small electrical issues.

To properly replace a heating element, you should have the proper knowledge of how electricity works. You’ll also need to remove the old element, which is typically secured by screws in the flange.

After the heating element is removed, you’ll need to use a wire brush to clean off the inside of the heater. Next, you’ll need to install a new rubber gasket.

Pressure relief valve

Whether you are experiencing a leaky water heater or just want to make sure your unit is operating properly, you should take a look at your water heater pressure relief valve. This is one of the most important parts of your hot water system, and failure to check it can cause you problems down the road.

The pressure relief valve is responsible for letting water out when you turn on your faucet. It also acts as an overflow to prevent your water heater from getting too hot. It is usually found near the water inlet or cold water inlet. If you have a problem with your valve, you may need to replace it.

There are a number of reasons your pressure relief valve could be failing, and you should check it out before calling a plumber. There are three basic options for fixing the problem: replacement, cleaning or re-valving. If you decide to replace your valve, you should consider the size and type of valve you are purchasing.


Identifying leaks in water heater repair in Houston is crucial to fixing the problem. The faster a homeowner finds the leak, the less likely he or she will have to deal with extreme water damage. Knowing the location of the leak is also important. It rules out impossible problems, making the process of fixing a leak a lot easier.

When a homeowner suspects a leak, he or she should check the water supply inlet, outlet fittings, and drain valve. If there is a problem, tightening the connections can fix the problem.

A leak can occur anywhere in a water heater. If a leak is located at the bottom, it is likely caused by a loose drain valve or the tank itself. If it is located on top, it may be caused by the flexible water supply tubes.

If the tank is cracked or corroded, it needs to be replaced. Alternatively, the tank can be repaired. However, these repairs are costly.
