Im getting confused now. A friend of mine has an old gloworm book & he says all old model fuelsavers flow was on the left. I know this to be true with the ultimate 100ff also.
Would you say all the F range has the same set up?? Or could they vary??
I would if the boiler was still connected. We have since fitted a new boiler in its place & used the pipes like for like but the boiler keeps turning off
