The area which I'm weakest in with irrigation installation has always been submersible pumps in lakes. I can design a system no problem, install the electrical components, and have the system completely functional, but making it look pretty has always eluded me. I was hoping that we could start a discussion on everything regarding pump installations in lakes. http://www.ms-irrigation.qc.ca/Photo 043.jpg This I found on the internet today and it looked like a good pump sleeve. Since submersible pumps are desinged to work standing upright, I imagine the little tripod leg he used will increase the life expectancy a bit. Something he doesn't do which I have seen other people do is on the two inlets, install a T so you suck water from the sides instead of the top.
