Following the fire on the pier, ( http://news.bbc.co.uk/1/hi/england/essex/4325430.stm ) Southend gears up for the shortest inquiry in history. Tuesday's Southend Echo, front-page lead story: Paragraph two: "Today an inquiry began into why a water main running the length of the pier, designed to help tackle a major blaze, failed in Sunday night's blaze." Paragraph three: "The plastic piping melted and cracked, leaving firefighters with no supply of water". -- <8P Wizard Suzuki GS550 "I like that.

All of you are probably right and someone without a clue installed PVC piping or something equally suitable. OTOH there's plastic and there's plastic. Advanced grades of glass fibre reinforced epoxy or polyester piping will actually withstand fire well and is allowed (and used) in oil processing installations including off shore platforms.
