how much to replace a ball valve
The $350 total labor seems perfectly reasonable to me-be sure he breaks out how much of that is for the warranty-covered work, then a second portion for the additional ball valve and pipe installation.herefore, you HAVE to install an expansion tank to absorb the expansion of the water as it heats up-this is standard nationwide plumbing code requirement, not just something your city requires. Ball valve and pipe materials probably only about $25-40 - not a big issue, in my mind.
