John,
I'm not arguing that it won't work, but there's one problem with dual tanks on a single compressor. Sure, they'll run longer - but they take equally longer to build both tanks back up to a useable pressure. Unless you're doing very short duration jobs, the compressor output is the critical path. I just couldn't put up with the constant waiting for the pressure to come back up.
By the way, what was the pressure rating of your water heater tank? I get a little nervous with tanks that aren't tested to the requirements of a compressor tank. If you get 100psi or so in a tank and it blows, it's literally a killer.
We'v had it up to 130 PSI b4 but normally 90-110 is the shut off point cause it's not automatic shutoff, takes a long time for it to get to 130 but, it does hold air for a good long while, even when using die grinders and other things like impact wrenches and air hammers, it's lasted about 16 years and it still works good.
