Had a nightmare recently, when a 22mm elbow came apart,(pipe blew out of fitting), at 4am in a customers house.! They didnt notice till about 7am, by which time the whole ground floor was under a couple of inches of water. I've been using hep, with their own plastic pipe, for several years now, and never had a problem. The above occured about a month after it was originally installed, and I sent the dodgy fitting back to Hepworth, for them to test. Havn't heard anything from Hepworth, (2 weeks now!), and the customer is wanting to claim on my PLI, for new carpets, skirtings, doors, hotel bills etc.... Have any of you guys ever had a Hep fitting fail on you, if so, what response did you get?? R.
