Tankless Water Heaters in Maple Valley: what is different here

Before we put a tankless heater on a rural Maple Valley well, we suggest the free water quality test, because iron or hardness can scale the unit. We also install, repair and flush units in the newer subdivisions near Wilderness Village and Shadow Lake. Our base is about 40 minutes away, SR 167 north to SR 18.

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.
