was called to a rented property I have worked in before - last year I turned the boiler off as it was a glowworm compact 30kw at back of terrace fed by 15mm pipe from meter at front of house this pipe also fed cooker and fire - when I tested the boiler pulled the fire and cooker flame to the point they nearly went out.went there this wk to change a rad to find a new vaillant pro 28kw and the ags pipe still 15mm from front to back. how do they get away with it.if I fit a 28 or 30kw boiler in terrace first part is 28mm then 22mm and on some still only got pressure.
