Water heaters should be installed in a dry, accessible area like a garage, basement, or utility room. The location must allow proper ventilation and meet Washington state codes. If you’re a new homeowner and don’t know the basics of water heater installation, including how to do it, where it should go, and how much it costs, read this guide.
Do You Need a Permit to Install a Water Heater in Washington State?
In Washington State, installing a water heater requires a permit to ensure safety and compliance with local building codes. The specific permit type depends on the type of water heater being installed and what it involves.
For instance, in King County, a plumbing permit is necessary for heater installations. Similarly, the City of Kirkland mandates a mechanical permit for gas water heater replacements and a plumbing permit if water piping modifications are involved.
How to Obtain a Water Heater Installation Permit in WA
- Check local requirements. Contact your city or county building department to determine the specific permit needed. This might include plumbing, building, electrical, and mechanical permits.
- Apply online. You’ll need details about your project, such as the type of water heater and
installation location.
- Pay the fee. Permit fees vary but typically range from $50 to $200.
- Schedule inspections. An inspector will verify compliance with local codes after installation.
For residents in Olympia, WA, the Washington State Department of Labor & Industries provides resources and contact information to assist with the permitting process.
How to Install a Water Heater
Installing a water heater in Washington doesn’t require a license or certification for homeowners, but it requires permits and a solid understanding of plumbing, electrical work, and local codes.
Even small mistakes can lead to safety hazards or inefficient performance. If you’re confident in your skills and have the necessary permits, here’s an overview of the steps involved.
- Turn off the water supply and power source. For gas heaters, turn off the gas valve; for electric, switch off the circuit breaker.
- Attach a hose to the drain valve of the old water heater and direct it to a drainage area. Open a hot water tap to release pressure and drain the tank.
- Disconnect the water lines, gas line (if applicable), and venting system. For electric models, disconnect the wiring.
- Place the new water heater in the designated spot, ensuring it meets clearance requirements from the manufacturer and local codes.
- Connect the cold water inlet and hot water outlet using flexible connectors or soldered fittings, applying Teflon tape to threads to prevent leaks.
- For gas heaters, connect the gas line with a flexible connector and test for leaks using a soapy water solution. For electric models, connect the wiring according to the manufacturer’s guide.
- Attach the vent pipe securely for gas units, ensuring proper exhaust. Check local codes for venting requirements.
- Open the cold water supply to fill the tank. Once full, check for leaks at all connections.
- Restore the gas supply or turn on the circuit breaker. Light the pilot or follow electronic ignition instructions for gas heaters.
- Set the thermostat to 120°F for optimal safety and energy efficiency.
Should You Install a Water Heater Yourself or Hire a Professional?
New homeowners in Washington can install a water heater without professional help, but it requires technical know-how, permits, and the right tools. One wrong move could lead to leaks, gas issues, or electrical hazards.
Hiring a professional water heater installation company might cost more upfront, but it saves you from potential headaches and ensures everything is done safely and up to code. They will also handle the permits and inspections for you.
If you’re not 100% confident, which most homeowners are, it’s okay. Just call a professional heating technician and focus on settling into your new home.
How Much Does It Cost to Have Water Heater Installed?
The cost to install a water heater varies based on the type of unit and the complexity of the installation. For a traditional tank water heater, you can expect to pay between $800 and $2,000, which includes the unit and labor.
Tankless water heaters are more expensive, ranging from $1,500 to $4,500, due to the higher cost of the unit and the more labor-intensive installation process. Hybrid water heaters, which combine tank and energy-efficient technology, typically cost between $1,200 and $3,500.
Additional costs may come into play if your installation requires plumbing upgrades, venting modifications, or permits. To get the best value, it’s a good idea to gather quotes from multiple licensed professionals.
