 Water Heater Installation: How to install?

If water heater installation is a headache for you, then approach a professional for installation of the water heater.

Stick till the end to this article to solve your water heater installation problem by following these 9 easier steps:


  • Disconnect all valves and empty the old water heater. To replace an old hot water heater, cut the lines, switch off the valves, and drain the water.
  • Replace the heater with a more energy-efficient one. Close the cold water valve at the heater’s top.


  • Turn off the gas valve and the heater’s electric supply at the circuit breaker, and watch the pilot light burn out to be sure no gas remains.
  • Connect a hose to the drain and let the water run.
  • Make a connection between the vent pipe at the tip of the heater and a grounding bar.
  • Remove any remaining unions using a pipe wrench or tubing cutter.


  • In your vehicle, transport the heater to the appropriate disposal site. If you can not carry it yourself, hire a removal service.
  • Assemble the new heater on top of the blocks. Lift the heater onto cinder or concrete blocks using a lifting trolley or a forklift; use blocks of the same size positioned closely together to reduce the danger of the heater dropping. Align it with the water and gas lines as best you can; you may rotate the heater later if it is not ideal.
  • The water heater mustn’t touch the ground during installation, since this may harm the heater’s exterior, damage low pipes, and reduce overall efficiency.


  • Install a new thermo-pressure relief valve. A tiny hose-like line emerges from the bottom of the thermostatic temperature and pressure relief valve.
  • Apply Teflon tape to the temperature and pressure relief hole, which looks like a big circle with an input slot.
  • Tighten the temperature and pressure relief valve using a pipe wrench.


  • Choose a copper relief valve to keep the lines clean. Copper is antimicrobial.
  • Put copper adapters to the heater’s water intake. Assemble a new adaptor for each 6 in. (15 cm) copper pipe. Secure the pipe using a pipe wrench. The hot water output should be surrounded by a red ring, while the cold water input should be surrounded by a blue ring.
  • A plastic liner “nipple” on the top of the intake valve may help control water quality if your region has especially hard water.


  • Put Water pipes to the heater’s top Align the copper pipes from the new heater’s intake valve with the water pipes from the ceiling or wall. Then solder the copper connectors to the pipes. From Fluency
  • If they do not match, solder elbow joints to the copper water heater pipes.
  • Reattach the vent shaft to the heater’s draught hood. Adjust the vent to be at least 1 foot (0.30 m) high before bending it.
  • Pre-drilling the draught hood holes makes it easier to line the vent shaft with the draught hood.


  • Reconnect the gas line. Screw one end of a steel pipe into the gas valve. Connect it to the tank and align it. Use two wrenches to decrease the gas valve tension and maintain one on the valve to stabilize it.
  • Cover the gas valve and the gas intake with plastic.


  • Fill the new tank with water and check for leaks. Turn on the main water valve and leave the cold water valve open. Turn on a hot faucet nearby and wait for the heater to start. Also, check for leaks at all heater joints. Does gas smell? Turn off the gas and the faucet, then solder the connection. If you do not wait, the gas could ignite.
  • The connections or soldering of pipes may repair water heater and gas leaks. Activate the valves, then tighten or solder the loose connection.
  • Turning on hot water throughout the house activates the heater, even if the pilot light is out, making it easier to check for leaks.


  • Set the heater’s pilot light to 120°F (49°C). After checking for leaks and tightening connections, ignite the heater’s pilot light and adjust the temperature to 120°F (49°C) following the manufacturer’s recommendations. Follow the manufacturer’s instructions to locate and ignite the pilot light on your heater.
  • The pilot light is usually hidden behind a detachable panel on the bottom of the heater, but check the instructions that came with it.
