When it comes to installing a new hot water system, such as a tankless water heater, the process is typically fairly straightforward. The water heater must be connected to an incoming water line, and an outbound water line should be connected to your home's plumbing. Despite the simplicity, there are a lot of mistakes that can be made along the way. Here are a few things you need to consider if you are going to install your own hot water heater.
Keep The Soldering Iron Away From The Tank
When you're connecting your hot water heater to the new pipes, you'll want to solder the pipes together to ensure that they are secure. Unfortunately, using a soldering iron too close to the water heating unit can result in damage to the unit itself. Many modern hot water systems are made with plastic casings that are susceptible to heat damage.
It's best to disconnect the pipe from the hot water system before soldering the connections. Then, once the pipe has cooled after soldering, you can reattach the pipe and then turn on the water supply.
Make Sure The Pipe Connections Are Similar
Any time you're connecting two pipes, as you will when you install a hot water heating system, you need to be sure that the pipes are properly sized. You cannot connect pipes of different sizes without risking corrosion, leaks, and further problems. That's why you need to be sure that the pipe diameter of your water lines, as well as the diameter of the connections, are all the same. This ensures that the lines are secure and free of any risk of leaks.
Along with the size factor, you also need to consider whether or not the pipes and connections are made from the same type of metal. If you combine metal types, you increase the risk of corrosion between the pipes and such.
Test And Validate The Relief Valve
Your hot water system will have a relief valve to help manage the pressure in your system. This valve releases any excess pressure that's built up to protect the integrity of your home's water heater system.
Any time you install any water heater system, you need to be sure that the relief valve is functional and is properly responding to the pressure in the system. Test the relief valve after you install the system, and talk with your hot water heater maintenance technician about how often you should test the system after the fact.
The more you understand and the more proactive you can be, the better your chances are of a successful hot water heater installation. Whether you're installing a traditional tank system or a tankless water heater unit, take these tips into consideration.
