    heard donny on here before mention that you need a return to tank valve on pump for cleaning roofs can anyone shed any light in this as im struggling to find them, how much pressure hose is it best to have for roof jobs? someone on here a while back made a bowser out of a wheelie bin with a float shut off valve etc has anyone got details on how to make these or something similar?

    you say a return to tank valve , maybe he was referring to an outer bypass , this causes the water to circulate constantly from the wheeliebin and through the pump , this stops the pump from over heating when you would be running the washer for hours on end , id say a minium of 20m of hp hose but on big houses you would want more so your not having to move the washer and water around the job
