From a different thread: I expect to throttle the pump and/or run the pump on low. I have a valve for that purpose ordered. The owners manual has flow/head curves that show the pump moves 45 GPM max and about 15 GPM @ 20' on low. High speed moves 95 GPM max, 85 GPM @ 30' and about 22 GPM (close to what I need) 80'.
The difference between SP1023 and SP1023G is the inclusion of a "sandwich washer" in addition to the standard washer with the -G. I think I'll be okay with the non-G fitting. If they leak, I'll order the sandwich washers (assuming I can) or return the non-G fittings and order G type.
