Health and safety for reach and wash systems should be more of a headache with these systems than trad, tralling hose's everywhere, trip hazzards, theres no end to probs with that, Ive used reach and wash, and dont think much of it, nor my customers. Two men with ladders no hassle what so ever, (cant beat hands on) I do think reach and wash is far easier than trad, but stil think trad is here to stay, and the brooms will be banned. Loads of water being wasted, cant be good.. But apart from everything I here with regards to the arguements concerning both, to pour water on to brick work, no matter how careful you are month in month out, will over the course of years, cause expencive damage to the morter and bricks, so think about that one, coz I dont think many people do think about this issue, if its high, then theres lots of different ways to get to that height safely.
