Hi,
im a GSR engineer but not from a plumbing background.
I have a customer with an open vented system that is having to bleed radiators downstairs and upstairs every few weeks.
I asked a plumber about this and he said it was either
1. A leak allowing air into system
2. The expansion pipe rises above the F&E tank by only 300mm and that this would allow air into the system.(there is almost no extra room to extend the expansion pipe above the tank due to limited space)
The solutions are to obviously find and stop the leak if there is one.
Or he also advised (and this were I have serious doubts!) to put a stop end on the expansion pipe and any expansion in the system will travel back up the return pipe into the F&E tank.
If after a few weeks the problem reoccurs then I obviously have a leak and could take the stop end off the expansion pipe.
This is my first time posting here so only helpful advice please,be gentle!
