FAQ:
Q: Is an expansion tank really necessary for a hot water heater?

Q: Why must a hot water heater have an expansion tank?
A: Because it reduces pressure, an expansion tank prolongs the life of your water heater. In fact, some manufacturers may void your water heater warranty if you have a closed plumbing system without an expansion tank.

A: How to Install a Hot Water Expansion Tank Step 1 – Shut off the Water Supply Step 2 – Turn off the Power Supply Step 4 – Size of the Expansion Tank Step 5 – Other Accessories Step 6 – Cold Water Supply Line Step 7 – Placing the Expansion Tank Step 8 – Fix the Tank Step 9 – Tee Fitting Step 10 – Connect the Tank Step 11 – Water and Power Supply
