Hi guys. I'm still digging my shallow wells in my backyard. I expect to need as many a 4 to supply my sprinklers.

If each well has water from 8' to 25' and assuming in total they can supply the required 15gpm for 2 hrs, can I plumb them in parallel and use 1 pump?

Next question:
I'm considering getting a pump off craigslist just to check well flow and recovery. I've found one that is cheap but very old. Assuming it works properly, is it the proper pump ? I would use it to check each well individually.
