    Re: Delevan tips

    Here's an old thread from PWI. I've had my Delavans plumbed together in tandem since 3/2007. Make sure you use a 30+amp switch running to a good 12V car battery.

    the way I read that is you have two supply lines each going into their own delavan but after the pump they go to a "Y" which goes to a 3/4" hose and gun

    Yes, I have a 3/4" T threaded to a 3 way Banjo poly ball valve with two intakes, one for water (rinsing) one for chemical.

    They are both drawing together at the same time with 3/4" hoses for intake and output to a 3/4" Stainless Super Swivel on a Stainless Steel Hose Track hose reel with 3/4" neverkink garden hose.

    This is the best 12V roof cleaning setup you can get besides the 3/4" hose could be better.

    If you want more flow like a 10+gpm roof setup like Apple uses, you would have to upgrade to gas power.

    After more reading it seems the dual set-up is more trouble than its worth...

    I believe that Russ scrapped it for that reason.

    Not for me. When one pump dies you have an instant backup, without having to install one in the field, because you will have them plumbed together already.

    Guys in the military are taught this same concept.

    One is none, Two is one.

    Two pumps will double your flow and double your speed. Nothing wrong with making more money in a shorter period of time.
