got a potterton puma boiler that is really starting to wind me up now it was working ok but one of my thermastatic valves got stuck in closed so dropped pressure to change it noticed quite alot of black nasty looking water so put some fernox f3 cleaner in which seems to be working ..
bleed the full system but now i aint got any rads coming on at all
have tried evrything i can think of but getting the 14lb hammer out
oh yeah the 22mm pipes are getting hot both flow and return and have made sure the boiler isn't air locked any help would be great
cheers
