I’ve built them where you can walk in to work on them. I also put a small skylight that opens so they can get the pump out.I'd love to see pictures. I have a small metal housing covering my pump that is hinged that I can lift up but I need to build something larger and better insulated. The guy that drilled my well told me if I ever built something to make sure the top of the well house was hinged or could easily be removed for access to make repairs and major maintenance.
