Newbie Xero Pure setup questions, booster and 2 poles

Just setting up my new Xero Pure. I am not truck mounting yet. Bought a Wanye Booster pump. Manual says no more than 10 feet away from water source. Is that true? If so I guess I plan to put system in driveway next to spigot and use 100-150’ of hose to reach around house. I may try 2 poles with the booster. Where would you “T” off for the best setup. The most logical spot to me is at the end of my 100’ hose to T or Y off of that to the 2 poles? Any help is appreciated. This is mostly aimed at single story solar panel cleaning. I am in area where we are very close to San Andreas fault and all old people so I am lucky to be working on 99% single story home!

You are exactly right at the end of 100 ft use ball valve to get equal water to both brushes. Normal use of this system is one pole since it can only produce 1/2 gpm. You can use DI for one pole and RO for other pole
