Hey all , looking to build a unit to pureifi my water to use as window cleaning water . Started up on my own . I have used the water feed Pole with the company I worked for b4 , but back then we just connected the van to the tap and filled it up , just looking advice on everything really , been reading up on the di vessels and they seem handy , could I buy a tank fill it with the hose and pump it threw the di vessel and the brush head ? Any help would be great !
