Greater Seattle & Eastside Water Heater FAQs

Answers to the questions , homeowners ask us most.

Don’t see yours? Call us at the number above or request service online.

Do you offer same-day water heater service in Greater Seattle and the Eastside?
Yes — Fast Water Heater Co. provides same-day water heater installation, replacement, and emergency repair throughout Seattle, Bellevue, Redmond, Kirkland, Sammamish, Issaquah, Mercer Island, Bothell, and Woodinville when you call before noon. Most Eastside addresses are within a 1.5–2 hour response window; Seattle proper typically sees 2–3 hours.
What permits are required for water heater replacement in Greater Seattle?
A plumbing permit is required for nearly every replacement under the Washington State Plumbing Code. Seattle goes through SDCI (seattle.gov/sdci). Bellevue through Development Services. Redmond, Kirkland, Sammamish, Issaquah, Bothell, and Woodinville use their own city building departments. King County areas go through DLS. We pull the correct permit and coordinate inspection.
Do I need seismic strapping for my water heater in Greater Seattle?
Yes — strictly enforced. Greater Seattle sits along the Seattle Fault and within the Cascadia Subduction Zone risk area. WA Plumbing Code requires two seismic straps on every tank water heater (upper third and lower third), anchored to wall studs or masonry. SDCI and Eastside inspectors verify this on every replacement.
What rebates are available for water heaters in Greater Seattle?
PSE offers strong rebates on heat pump water heaters ($800+) and high-efficiency tankless for most Eastside addresses. Seattle City Light offers HPWH and conservation rebates for Seattle customers. The federal 25C tax credit covers up to $2,000 for HPWHs. The IRA HEEHRA point-of-sale rebate (up to $1,750 for income-qualified households) is rolling out via WA Department of Commerce.
How does Greater Seattle water hardness affect water heaters?
Greater Seattle water is famously soft. Seattle Public Utilities (Cedar River + Tolt) runs 1.3–2.6 grains. Cascade Water Alliance / Eastside utilities are similarly soft. Even with soft water, annual flushing on tank units and quarterly descaling on tankless protects sediment buildup and longevity.
Can you install a tankless water heater in older Seattle and Eastside homes?
Yes — we routinely retrofit Rinnai, Navien, Noritz, Rheem, and Bradford White tankless units in pre-1940 craftsman, Tudor, and Cape Cod homes throughout Capitol Hill, Wallingford, Queen Anne, Ballard, Magnolia, Madrona, Madison Park, and the older Eastside neighborhoods (Old Bellevue, Houghton, Old Town Bothell). We handle gas-line resize (often 1/2″ to 3/4″), dedicated 120V outlet, condensate drain, and Category IV venting required for condensing units.
How fast can you respond to a water heater emergency in Greater Seattle?
Same-day response is standard for calls placed before noon. Eastside (Bellevue, Redmond, Kirkland, Sammamish, Issaquah, Bothell, Mercer Island, Woodinville) typically sees 1.5–2.5 hour windows. Seattle proper (Capitol Hill, Ballard, Queen Anne, Wallingford, West Seattle) typically sees 2–3 hours. North Seattle and Snohomish County edges may add an hour.
Do you handle gas, electric, and tankless water heaters in Greater Seattle?
Yes — full lineup. Standard gas tank (40, 50, 75 gallon), electric tank, gas tankless (condensing and non-condensing), and heat pump water heaters. We are authorized installers for Bradford White, Rheem, AO Smith, Rinnai, Navien, and Noritz, with the most common Greater Seattle sizes stocked at our Eastside warehouse for same-day swap.
