New Water Heater Installation – How To Install

Overall, water heater installation steps are simple: connect the pipes with flex hoses as needed, allow cold water into the system, properly set a pilot light if using gas for power, check for leaks or loose fittings, test the system and run water out of a faucet to ensure the new water heater functions as intended. DIY water heater installation help is available in many places as text, video instructions and so on. Therefore, what follows are guidelines regarding specific steps of water heater installation that merit closer scrutiny.

Temperature and Pressure Relief

The temperature and pressure (T&P) relief valve must not be capped or sealed since it prevents explosive pressures from building up within the water heater system. To ensure safety, it can help to install a thermal expansion tank. This simple tank will help deal with lots of pressure and function as a backup to the T&P relief valve. This article from SFGate Home Guides details troubleshooting steps relating to the all-important T&P Valve.

Pilot Light

Make sure to turn on the pilot light once the new heater is in place. Don’t be surprised if it takes a few tries before the pilot light connects. Keep in mind, though, that excessive efforts to turn on a pilot light are a potential hazard. Ventilate the area for about fifteen minutes after several failed attempts before trying to ignite a stubborn pilot light.


To get the most out of a water heater investment, reasonably priced insulation will stretch water heater efficiency. Professionals stand by recommending insulation even though it is not strictly necessary for water heater function. For example, Imagine Plumbing & Appliance up to 45 percent greater efficiency from this simple investment.


Testing involves looking for proper water flow, proper heating and system leaks. Testing water flow involves checking proper water pressure throughout the water delivery system, such as a hose. 50-60 PSI is the ideal water pressure range. Gas leaks should be checked by brushing some leak detection solution, such as slightly soapy water, in the vicinity of joints, pipe bends and anywhere else that a leak may occur.


Gas lines, hot water and heavy lifting involved in the process argue for prudent safety measures and plenty of education and training regarding water heaters. The above guidelines on specific steps within the water heater installation procedure will ensure that the new water heater functions well and for a long time.
