I saw a 4 inch one once in a high level water tank for filling up steam engines this reminded me of it centralheatking

Lovely piece of brass and that soldered copper float is a thing of beauty.

No water hammer with that one Shaun it's an Equilibrium type & don't go swopping the copper float for a plastic one as they are a match pair.
I used to know 3 places in South London that you could walk in & buy a 4" version let alone that tiddler!!
(CA Baldwins & H&B's are still going i believe but not checked their stock levels of late 🙂)
