Step #1. Shut power and water supply

One of the essential steps in installing units is the checking stage. The checking stage will see the joints and the settings at the correct valve or the right temperature. Ensure the new water heater is checked to see if it has both temperature and pressure relief valves installed correctly.


Step #6. Expansion valve and tank

Now, some water heater unit needs an expansion valve and tank. For what purpose are these expansion tanks for? These expansion tanks and valves I’m talking about will aid your water heater when too much pressure comes out of the heated water. The pressure from the water heater will go through the expansion valve and stay in the expansion tank until a certain pressure is stable; the valve will release the water from the tank.


Step #7. Testing

To test if you have wholly and successfully installed the new water heater, plug the water heater in your power outlet and start turning the water supply back on to fill it. Check for possible leakage from the pipes and valves ensure that it is tightly closed. Then try testing the new water heater to see if it works well the way you want it to be.
