Before you start any water heater repair project, you’ll want to check a few things. First of all, check the thermostats. If the top thermostat is defective, the entire water heater will stop producing hot water. If the lower thermostat is faulty, the water will be lukewarm, and you’ll run out of hot water quickly. To test your thermostats, you need a multimeter or a voltage/ohm meter.
Whether you’re dealing with a tank-type water heater or a gas-based model, it’s important to have it checked periodically. If mineral deposits are present, or if you can see half of the wires, it’s time to replace it. Also, be sure to clean the burners of gas heaters on a regular basis. Make sure that the area around the water heater is clear of debris and has two feet of clearance. Also, make sure that the thermostat is set at the right temperature.
Other common problems include cold water, a leaky tank, and scalding water. These issues should be diagnosed by a plumber, as these are usually signs of a bigger problem. Symptoms of lack of hot water, or lukewarm water, are usually caused by a faulty circuit breaker, a bad thermostat, or a cracked dip tube. However, if these don’t solve your problem, you may need to replace the thermostat.
Depending on your water heater type, it is crucial to learn the basics of how it works. While gas-powered water heaters are easier to repair than electric models, their problems can also occur. Gas water heaters use burners rather than heating elements to heat water, so they can develop problems as well. If you are unsure of which model you have, ask a plumber to check it out for you. If it fails to meet these requirements, he’ll be able to recommend a suitable repair for your needs.
If you hear banging noises coming from your water heater, it’s likely that the temperature and pressure valve has failed or a pipe has become loose. This is a major problem that may require a water heater replacement. If the water is rusty, the inside of the heater has corroded. A plumber will clean the interior of the water heater and flush the water out of it to ensure it’s working properly again.
Expert plumbers are knowledgeable about water heaters, and can diagnose the problem quickly. This means they can complete the repairs as quickly as possible. Expert plumbers are educated about the design and functioning of water heaters, and are aware of all the safety standards that apply to them. In addition to having the knowledge to perform water heater repair, these plumbers can also fix many other problems, including leaky faucets. The most common plumbing issues require a plumber to diagnose the problem and recommend a replacement.
In addition to finding the leak, you should also check the pilot light. Sometimes called the door switch, the high-limit reset switch is located in the bottom of the water tank. To see where this switch is located, watch the video at the 18:30 mark. Press and hold the button for a minute. If you still can’t see the pilot light, try relighting the pilot. This will ensure that the water heater is running safely again.
