I'm using a 60 psi pump with the pressure switch disabled. I have 10 metres from my micro bore hose reel up to the brush. No problem up to now, I think you can buy 10 metres for about £4, won't cost a fortune to try it.
Jeff Brimble has been using it for a while and still does. I think it's the dogs, no need for a control tap, just pinch it or fold it and the flow stops. Dai
