Welcome to AZ ,you have a nice setup there ! It looks like the engineer types have you straightened out on the pump choices and selection. I have a question about your pump area. Are the pumps on a pad or sitting on the dirt/rocks? They look like they are sitting directly in a low spot for drainage. If so I would suggest putting everything on a pad especially if you are replacing components, now would be a good time. Pics can be misleading so it could just be me looking at it wrong.
Bring on the summer heat!
