I would make sure it is mains fed. Have you got a water tank in the attic? If you dont you have to trace the black water pipe feeding upstairs and ensure there is no stop cock after being half turned off. I am sure its not mains fed as this is just wrong check around for that tank. wheres the hot water cylinder? now follow the feed (usually fed in on the top) from that and see where you end up or come accross. ps in ireland the mains operates i think around 7bar and this is more than enough 4 uo to 6 story high buildings
