Hi guys
Is it normal for the cold feed pipe from the f&e tank to be combined with the open vent?
The cold feed connects to a 22mm tee one end is the vent the other cold feed to rads
I thought the vent connects to ch flow and the feed to ch return?

Thanks in advance
 
It's one way it was done a few years ago .
I'm personally not a fan as you tend to have to fill up slowly to prevent air locks.
You would only have vent on flow cold feed on return on a old gravity system.
Most tank feed fully pumped systems were connected using a close coupled method ie boiler flow open vent tee then cold feed normally within 150mm often in a H section.
 
It was quite common once upon a time usually to get over air ingress problems and pumping over issues , works well on some older systems but can be difficult to fill up and vent if drained down.
