Thanks, I might print this off. What I'd been doing so far, is to hook up
compressed air. Burp out the various faucets. A couple have a WH drain
petcock, which gets opened. Burped out. And then, the pump with the pink
stuff, pink out all the faucets. Which pink takes care of the traps.

One or two, the WH drains via removing the anode. That's a bit more work,
bleed off the pressure, and then gravity drain. I found that removing the
anode while the system is still under air pressure, results in me needing to
go home for dry clothes. Lot of sediment particles in the WH, also.

I've not found a bypass valve behind the WH, any of the trailers. Not found
a low point drain, either. Must be older trailers?
