Looking at this one that MK advised a while ago! http://www.jetmac.co.uk/13hp-loncin-jetwashers?pm2_a=show&pm2_id=21#!prettyPhoto[pi]/1/ A couple of questions. Does it have to be 13hp or can you work ok on a 5hp(around that mark) Am assuming you use outdoor tap? Or do you use your tanks in your van? If you use outdoor tap and there wasnt one, can you use one of them hozzlelock adaptor for the kitchen sink, any good? Come across posts(Smurfs) where you use a bin for water? Whats that about?
