I would much appreciate a little advice. This is a typical fully-pumped system maybe 8 years old which has had a problem with air in the system from new.
The flow pipe from the boiler rises in the airing cupboard, first tee is the 22mm feed pipe, second is the 22mm vent, then the pump, followed by a 3-port mid-position valve. Now, according to what I read, the feed and vent pipes are the wrong way round in this arrangement.
Given that the two tees are only 8cm apart, is it likely that reversing them will make a significant difference ?
Thanks, pcr.
