Get a drain pan and place it underneath your water heater to keep your basement, garage, or attic from flooding. Most water heaters come with temperature and pressure relief valves. If your unit doesn’t have one pre-installed, look for it in the box, or visit the manufacturer website to see if you need to buy one.
Don’t recycle your old heater’s T&P relief valve. You may, however, reuse your old discharge pipe.
Attach the discharge pipe to your T&P valve and point it toward a bucket or a drain. It will discharge water when excess pressure builds up in your heater.
Your heater will come with a flexible water hook-up, which will look like a metal kitchen hose. Put plumber’s tape on the heat traps of your tank and attach the hose there with a wrench.
Put plumber’s tape on both ends of the connector body threads included with your hose kit. Connect the hose to it, and then hold it next to the water supply pipe. Mark, cut, and de-burr the supply pipe so that it lines up perfectly with the hose with a small allowance.
Put a compression nut up the supply pipe, then insert it into your hose kit’s connector body. Screw the compression nut onto the connector to form a tight seal.
Some states require that you brace your water heater with seismic straps to prevent it from toppling over in the event of an earthquake. Different manufacturers have different ways of strapping in their tanks, but generally, you need to install two straps: One 18 inches from the bottom of the tank and one 6 inches from the top.
These straps should attach to two wall brackets that you may have to purchase separately. Make four pilot holes in the studs of the wall and secure the straps using a ratchet and socket.
Take away the aerator from your kitchen faucet and let it run cold. It should take a while before your tank fills up with cold water. Use that time to check your pipes for leaks.
Your tank must be full before you start heating water. Dry-firing your heater will ruin its heating element.
You will find a junction box on top of your heater with a screwed-on cover. Remove it and hook up the ground wire together with the ground screw. The ground screw on most models has a green indicator.
You can also use the labels on your previous unit as a guide since the electrical design of water heaters has not changed since the early 2000s. Conjoin the ground wire and the ground screw by twisting them together using the wire connectors, and then put back the junction cover. Turn on the power from the circuit breaker and see if your heater powers up.
If your heater is not receiving power, re-check your connections. Always turn off your circuit breaker whenever you open the junction box. It might take several hours to heat a fresh tank of cold water.
We recommend that you put 120 degrees Fahrenheit as your initial temperature. If you see water coming from the discharge pipe, it means that your water is too hot.
The average weight of an electric water heater is 150 pounds. Replacing it requires more than one handyman, which is why mainstream home improvement companies can charge up to $2,000 to do it for you. Though you may know how to install an electric hot water heater, you could still injure yourself in the process.
