I just bought 10 acres of farm land in Central California. The well pump and control switches have a rough wooden enclosure which I plan to replace because it's about ready to break into 1000 pieces.

Are these enclosures just to keep rain and water off of the pump and switch assembly? They look like they could actually do just fine out in the open. And I don't understand why they covered the pump but not the pressure tank. I'd be willing to cover both if there was a benefit. Or cover neither if it does not serve a purpose.

What do you think?

Thanks,
Martin
