Would welcome any advice, had a loft conversion 3 yrs ago and had shower room fitted with a Stuart Turner 3.0 bar twin Neg head pump which is in our airing cupboard on 1st floor. Woke up yesterday to no water at all in the loft shower and basin. Up till yesterday had not had any problems, no diff noise, no burning smells or steam, worked perfectly. Now its completely dead. Have changed the fuse but didn't make any difference. Water tank on main landing and other bathroom fine (not connected to neg head pump). Any ideas and costs ? so I can let hubby know the bad news !!.
