Air relief valve

Does anyone have experience with these valves https://www.flomatic.com/valves/air-release-vacuum-valves/clean-water/comboair/

I am trying to size one for the well at my cabin that drains back into the casing to prevent the lateral from freezing. It is a 1” line 400’ long with a 1 hp 10 gpm pump.

I have used similar Cla-Val and Watts. That should do what you want.

Do you think I should go with the 1” model?

1" should be plenty. But is all about the orifice size inside those valves. I read the specs. Sounds like the large orifice in those will be fine.
