Tankless Water Heaters in Federal Way: what is different here

Federal Way homes from the 1960s to 1980s near Adelaide and Jovita were built around a tank, so a tankless switch can need new venting. We look at the space and the route for the vent, then quote a flat rate. We are about 25 minutes north on I-5. Check with the City of Federal Way about permits.

How the job runs

  1. Check supply and venting

    We check your gas or electric supply, venting path and water lines. Tankless units need more fuel than most tanks.
  2. Size and price

    We size the unit to how many taps you run at once and give a flat-rate price before work begins.
  3. Install or repair

    We mount the unit, run venting and connections, and add service valves so it can be descaled later.
  4. Test and show you

    We test flow and temperature at your taps, check for leaks, clean up and show you how the unit works.
