What is the average cost of labor for replacing a gas valve on a hot water heater?

I had a gas valve replaced on my 40 gallon hot water heater.

Tough question as there are many variables. These include local labor rates which vary widely across the country, how hard to access the valve and therefore how long the job will take, whether there is a trip charge on top of the actual labor performed, and whether the gas connection has to be brought up to current code or not. Since you've already had the valve replaced, I'm guessing the water heater was no longer under any warranty and that you decided to not replace the entire unit.


Based on lots of plumbing work I've had done in several States, it would not be unreasonable to expect an appropriately-licensed plumber to charge a $75 trip fee, plus hourly rates about $75/hr - $150/hr or more depending on distance to your location, local demand, local supply of qualified plumbers, etc. Call a few plumbers locally and ask them how they charge for what you want. Better yet, see if anyone you know recommends a plumber and contact that person first. The other variable is how long it takes to actually change the valve. The plumber will have the knowledge to do this quickly, but your configuration may take longer than expected due to things like:


1- can the valve be accessed easily?

2- is there enough room to get to the valve and use tools efficiently?

3- are there any gas leaks in the gas lines?

4- does the gas line have to be brought up to current codes?

5- are the valve fittings a straight replacement or does the gas plumbing have to change?


Any of these will require more time and therefore be more expensive.

You did not say if this was the gas regulating valve (with the temperature control and ON-PILOT-OFF switch on it) or just the gas shutoff valve on the incoming gas line. Generally, either should be able to be replaced in 1/2 hour assuming reasonable access and no other code-required upgrades had to be installed, so the minimum service callcharge of $75-150 (to $250 in a few large cities) would commonly cover it, or come awfully close.

Note that you asked for LABOR cost - the valve itself typically costs about $25-50 for a gas shutoff valve, and from occasionally as low as $50 to usually about $100-200 for a gas control valve - which for an older water heater can sometimes make heater replacement look like a good choice.
