Ecotec plus 824 cold water inlet valve.

Mine's leaking into the fill hose. If I leave the hose connected and isolate at the other side it's usable temporarily but is not ideal.

I think the tiny bore in this valve is also restricting the hot water pressure at full flow.

I'd like to replace it with a straight coupling. (and put the fill loop elsewhere) There's already a full bore 22 mm ISO for the cold water feed before the boiler so it won't be a servicing issue.

Question is...what's the fitting on the boiler / can I even buy such a thing?

It's a flat face coupling of some description. About an inch in diameter. It's isn't a G1" (tried buying a G1" to 22 mm meter union from Screwfix - they're huge)

Else...has anybody removed an Ecotec 824/831/837 (or are they about to) and kept the HOT water outlet pipe / fitting rattling around in the van? Swap for beer tokens? That'd be perfect...
