Hi Roy. The OP is a student trying to understand 'close coupled' tees and why they 'MUST' be no more than 150mm apart, not trying to understand 'combined feed and vent' arrangements.Here's another thread with discussion of combined F & E (22mm min)
Combining feed and vent piping from F and E tank
It would save me a lot of faff if it was acceptable to combine the feed and vent in the manner shown in diagram below. Or should I resort to separate pipes for each, as small sketch. Boiler is Potterton Suprima I would be grateful for your advice. Thanks Rudywww.plumbersforums.net
I also have a hazy memory somebody gave a link to where the F& E standards are all available on the internet? (Crook heights, pipe sizes, keeping pipes sloping etc.)
Cheers,
Roy
