I've just installed a long length of John Guest Speedfit BPEX pipe only to find that it is completely blocked. I can't blow down it at all, another length similarly installed is OK.
I've checked the length of pipe - approx 20m - which takes a circuitous route around the loft (through joists etc) and it is completely free of sharp bends, kinks etc and all looks OK from the outside.
Has anybody else ever known of plastic plumbing pipe to be blocked on installation like this?
I assume it's a manafacturing fault which is a little worrying - is it too thin somewhere else and going to rupture??
