Hot water and boondocking

[Wilhelmus Schreurs]

Chuck and Gardner:

Am interested in this as well, by why can one not use the cold water line with a
few solenoids as well??

Chuck,

Thanks. By the way, My wife's name is Kathy also, so it seems

that wives named Kathy like the solution, so it must be a winner.

I like the idea of using relays so that the pumps don't fight each

other. I have a similar relay logic system in my home. The garage

and bedroom share the same supply side for the hot water heating

system, so I built a relay logic system that gives the bedroom

priority. A little boolean logic and some radio shack relays and you

are in business.
