Expansion Tank Installation

What this involves.

An expansion tank gives heated water room to expand, which protects your water heater, valves, and fixtures from the pressure that builds up in a closed plumbing system. We confirm the tank is sized for your water heater and set the air charge to match your home's water pressure before it goes in. We mount it in the correct spot on the cold supply, support it properly, and connect it so it does its job without stressing the line. After installation we check the system pressure and confirm the relief valve is no longer being pushed. The result is steadier pressure and a longer life for your water heater and plumbing.

• Confirming the tank is sized correctly for your water heater
• Setting the tank's air charge to match your home's water pressure
• Mounting the tank in the right spot on the cold supply line
• Supporting the tank so its weight is not on the piping
• Connecting it cleanly and checking the joint for leaks
• Verifying system pressure and relief valve operation
• Walkthrough of what the tank does and signs to watch for
