How to Change Water Heater Connector Hose

Water heater supply lines can corrode and leak at the connection nuts. When this happens, it is important to replace the connection lines. You can buy new hoses for your water heater at most hardware stores.  Once you have your new replacement lines, follow these seven steps to replace your water heater connector hoses.

Step 1: Turn off the power to the water heater at the breaker switch.

Step 2:  Turn off the cold water supply valve connected to the cold intake line.

Step 3:  Drain the supply lines by running both hot and cold water from your kitchen sink faucet. Allow hot and cold water to run for a few minutes each.

Step 4:  Pull up on the pressure release valve located on your water heater and hold it up for a few seconds to allow the inner tank pressure to subside.

Step 5:  Remove the cold water intake supply line and the hot water output line hoses.

Step 6:  Attach the new water heater connector hoses. Make sure the rubber gaskets are pushed into the bottom of the connector nuts on each supply line. Connect cold water line to the intake marked "Cold" or "C" and the pipe with the cold water supply valve.  Secure each connection firmly.
