Water Heater Repair and Replacement in Spokane
A leaking or dead water heater in Spokane comes down to three questions: repair or replace, tank or tankless, and who handles the permit. National guides put a standard tank at $600–$3,100 installed and most repairs at $150–$700 (read November 6, 2026). Ask the permit office for your address whether a replacement needs a permit; we have not read the City's water heater rules. Once quote requests open, Spokane Elite Plumber can pass your request to an independent local plumber, who would quote the job.

If it is leaking right now
- Close the cold-water valve on top of the heater If it will not close or the leak continues, close the main shutoff.
- Cut the energy Gas: turn the control to off. Electric: switch off the breaker. Do not touch electrics while standing in water.
- Find where the water is coming from A fitting or valve on top can be repaired. Water from the tank body means replacement.
Repair or replace
- Repair when the tank is well inside its 8 to 12 year life and the fault is a part: a heating element or thermostat ($100–$350), a thermocouple ($100–$325), a gas control valve ($150–$550) or a relief valve ($50–$300).
- Replace when the tank itself leaks, when rust shows in the hot water, or when an old unit needs a repair that costs a large share of a new one.
- Maintain in between: a flush runs $75–$250 and an anode rod $150–$350 nationally.

What a complete quote covers
These are general installation points, not a summary of Spokane's code. Your permit office and its inspector have the final say on any of them:
- Whether a drain pan is needed where the heater sits, and where it drains.
- Whether the home needs an expansion tank.
- Where the temperature and pressure relief valve discharges.
- Gas line size and venting for the new unit, especially for tankless.
- The permit and the inspection, shown as their own line.
Who to ask about permits: Spokane plumbing permits.
Questions to ask the plumber
- What is the company’s Washington plumbing contractor license number? (How to verify it with L&I.)
- Is the permit on the quote as its own line, and who books the inspection?
- Does the price include the pan, expansion tank, new flex connectors and haul-away?
- If going tankless: does the gas line need upsizing, and is that in the price?
