Here is the system i have set up. I can't seem to figure out how to attach a picture -- i have a 4" line, reduced to a 3" line, reduced to a 1 1/4" line -- shoots water up about 2 feet. My submersible is a 3hp.
Also, on the restriction, rather that turning it off at the electric, we turned it off at the valve and it spun the pump off -- not sure what that meant, but i know it cost money to fix it.
