When installing a new hot water heater, it's important to make sure the job is done right. The following are five common issues that can affect the installation, along with how to avoid them.
1. Carbon Monoxide (CO)
CO leaks can occur due to a faulty installation. First and foremost, make sure that you have a working CO detector installed near the water heater. Second, verify that your installer checks the water heater vents to make sure they are fully functional. Vents can become blocked by debris, which can cause CO to collect in your home instead of being safely vented outside. The installer also needs to make sure all the vent fittings are secure so CO doesn't leak back into the home.
2. Dangerous Temperatures
An overly hot water heater can cause burns if the tap water is too hot. Even more alarming, though, is that too high of a temperature can cause the water heater to explode. Your installer must check that the thermostat on the new heater is working properly. Further, they will also install and test an overflow tube on the pressure release valve. This tube routes any overflow due to temperature or pressure issues safely towards the ground.
3. Installation Leaks
You can't just turn on the water heater after installation and hope it is ready to go. This is called a dry run, and it can cause the tank to crack. This is because the inside of the tank is still dry, so heating the dry tank leads to a crack. Instead, open all the hot water taps in the house and allow them to run for several minutes, or at least until the flow is steady with no sputtering. This indicates that the tank is full and you can now fire up the water heater to heat the water.
4. Fitting Failures
Fittings fail on a new water heater due to attachment issues. Most metal fittings are soldered into place during installation. If there are any mistakes, then leaks will develop around the fittings. Your installer needs to fill and check all the fittings following installation to make sure they are secure and not leaking.
5. Power Interruptions
Power interruptions, such as tripped breakers and overloaded circuits, are most likely to occur if you are upgrading to a higher capacity hot water heater. If your old smaller unit shared a circuit with other items, the larger unit may draw to much power and lead to tripped breakers and power interruptions. Your installer can install the new hot water heater on its own dedicated circuit to avoid this problem.
