My neice in the Houston area is house sitting for some people and doing some work in lieu of rent. They have two very old 40 gallon gas water heaters to be replaced (not leaking yet). They are in overhead (attic) areas.
She isn't about to install gas water heaters, but thought it might save some money if she got the old ones drained, cut the pipe close to the heaters, shut off the gas and disconnected it, removed them from the space, and got the new ones into the installation location.
She is a mechanical engineer who rebuilt her own old Mustang and works in a machine shop in her spare time, so I'm confident she can shut off the gas. She will probably hire a couple of strong immigrants or Katrina transplants to do the heavy lifting.
Will it be worth enough to the plumber to save them a good bit on the installations? And should she get the plumber to order the heaters or try to get them herself? What brand? Rheem? ???
