Thanks for coming back with the outcome.

I always fit a check valve the pipe size above to avoid any flow restriction.

Good point. I considered doing this, but was able to source a full bore 28mm check valve. I also discovered that "full bore" means different things to different manufacturers. It's only when you compare side by side you truly see which is better. For example, Altecnic full bore lever valves are just that - unlike some other brands (!)
