My water supply comes from a borehole, about 4m deep I think, with a submerged pump. The pump seems to be on the end of a galvanised steel pipe that carries the water up. It works but the water coming out (I've just restarted it after a couple of years disconnected) is full of rust and about as transparent as cream of tomato soup.
It seems to me that the pipe must be terribly rusty. It is about 20 years old and I want to replace it before the pump drops off the end and gets stuck down the hole.
What should I replace the pipe with? Copper, stainless steel, plastic? - or just hang the pump from a rope and use a flexible hose for the water?
Thanks
Roger
