Hey Jason, any chance of getting a group buy discount for us Supra owners on the 1100lb sac?
Steve,

If I am not mistaken you should be able to get about 40 GPM out of a 3/4" intake, so it should not slow down too much when all three pumps are running.

However, the 800's are rated for 13.4 GPM but after all the friction loss and going through the vented loops, I am only getting about 10 GPM into the bags. I will say after two seasons without the sprinkler valves it has been working awesome, reliable and simple.
