Introduction
Installing a new water heater is more than just plugging in a device. It’s a systematic process that touches plumbing, electrical, and safety protocols. In this article, we walk you through the installation process, plus key decisions you should make ahead of time.
Why installation is a big deal:
- Sets the foundation for years of reliable performance
- Mistakes can lead to leaks, inefficiency, or safety issues
- The right installation ensures compliance with local codes
- A well-done install reduces maintenance headaches
Step-by-step installation process:
- Assessment – measure space, check venting, plumbing, power or gas lines, and unit size.
- Remove the old unit – shut off utilities, drain, disconnect lines, and remove carefully.
- Position the new heater – place level, secure, add seismic restraints if needed.
- Plumbing connections – attach supply lines, secure fittings, check for leaks.
- Gas or electrical hookup – connect properly, test for safety.
- Safety components – T&P valve, expansion tank, and venting checks.
- Filling & testing – fill tank, purge air, power up, test hot water delivery.
- Cleanup & final walkthrough – clear site and review operation with homeowner.
Common pitfalls to avoid:
- Undersizing or oversizing the unit
- Poor venting on gas models
- Skipping seismic restraints in certain regions
- Mixing metals without dielectric unions
- Incorrect wiring or gas line work
- Failing to leave access space for future service
Cost & time considerations:
- Standard installation: a few hours to half a day
- Complex setups: longer if relocation, rewiring, or venting upgrades are needed
To save money:
- Stick with the same heater type if your setup works
- Avoid moving the heater to a new location
- Prep the area beforehand
Tying back to repairs:
If your water heater is only showing minor issues, repair might be cost-effective. But if multiple parts are failing, installation becomes the better choice. For guidance, check our blog on 5 warning signs of failure or see our full Water Heater Repair or Installation service.
