Never seen this before- was it common practice way back then?
Looked at a job today to change some very old rad valves on some very old radiators. The elderly chap was a 'Qualified heating engineer' but not a fitter, design and sales it seems, retiring at the end of the sixties.
Anyway, it turns out that his 'vent' is just an extension of the indirect feed into the cylinder with a manual air vent on the end which stays shut. 'Don't like inhibitor' he said, 'Don't need it'. Normal 15mm/1/2 inch feed pipe from header. Reckons this arrangement is safe and problem free. 'Ooeer' I said!
Any thoughts?
BTW, the rad valve heads looked like flat cookies or the top bit of USS Enterprise straight onto the body of the valve. Cream plastic, not the long spindle sort you used to see in school etc. Open to shut in about a quarter turn with a gauge marked on there. He reckons they were the muts in those days- I've never seem anything of the like- and I'm no spring chicken!
