I currently do my cleaning using a gardeners backpack and 25ltr barrels. In the next few weeks I will begin to build a DIY setup in my van. Was just wondering is it just a case of running hose from tank to pump and then to hose. I want to do all i can to avoid any air blocks. I want to avoid as many schoolboy errors as poss. ( I will be filtering my water at home so dont need to worry about that) TIA
