Notes
- Where the number comes from. The national price for a gas tankless water heater installation is $3,700 installed — water heater replacement pricing published for 2026, unit plus installation. Labor is about 45% of that. Plumbers, Pipefitters, and Steamfitters near Tri-Cities, WA average $88,800 a year against a U.S. mean of $72,170 — a factor of 1.23 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for plumbers, pipefitters, and steamfitters near Tri-Cities, WA, so this is the Washington state average, SOC 47-2152.
- This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Tri-Cities, WA, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
- What is in the price: the heater, removal and disposal of the old one, new flex connectors, a drain pan, an expansion tank where code requires it, and labor.
- What is not: a gas line upsize, new venting, an electrical circuit for an electric unit, and bringing an old install up to current code. These are the lines that turn a $4,084 quote into a $5,105 invoice, so ask about each one before signing.
- Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

Why the city changes the number
About 45% of this job is labor — $1,838 of the $4,084 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.
Plumbers, Pipefitters, and Steamfitters near Tri-Cities average $88,800 a year, against a U.S. mean of $72,170. That is a factor of 1.23, so the labor half is scaled by it and the material half is not.

What the quote should include
The lines that turn a quote into an invoice
Ask about each of them before you sign. On a job this size they are the difference between $4,084 and something a quarter higher.
Use it as a bid check, not a quote
This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.
If a bid lands outside $2,759 – $6,622, that is not automatically wrong — but it is the question worth asking out loud.
