What size ball valve???

It's not being funny, 1/2" BSP is common but 3/8" BSP is used to, and goodness knows what other folk might be using.

My turn to be sorry! I'd have to dig about a bit for 15mm 'cos I've only got BSP to hand. May be a day or so.

1/2" BSP is 21/22mm size hole ... 15mm is approximately the same thread diameter as 1/2" BSP, just a tad smaller, so I'd be looking at 20-21mm

IIRC 21mm comes to mind it was a good tight fit and easy to seal up when the tap is fitted

Wow only been out of brewing for 2 years and I've forgot how the ball valve taps are secured to the vessel
