"Our house is a part stable , part barn which we are converting into our home, the flexibility of the pipe allows us to overcome the many twists, turns and changes in level, as well as long runs of joint free pipework allowing the free flow of water. I had previously used white plastic pipe but I find the grey polypipe far superior in flexibility, cutting and jointing."
"I bought this to run cold water from one side of the house to the other through a complicated route. It would have taken days to solder it up in copper pipe but took half a day to route the poly pipe. Used pipe stiffeners and brass compression fittings to connect back to copper at either end. Wouldn't want to run it on the surface though - it's difficult to make it look neat."
