"Copper Pipe 15mm x 3m Imagine, if you will, a 3m solid copper rod. Now imagine someone drills a hole all the way through it. Hey presto copper pipe. Now you can use it to run water or gas through it. It can even be used to suck up those really thick milkshakes you get. It's copper pipe! It's cheap. It works."
"What is there to say about plumbing fittings! They do what it says on the box! Service is good from Screwfix and everything was in stock. Reasonable prices and small quantities available if required."
