With all the Maxi-paws you have in service, why would you care about "conserving energy" unless this is some kind of "green, sensitive new-age contractor" kind of thing. If so, please explain.

Do you not know that flexible pipe will "absorb" the kinetic energies produced by heads using impacts to provide drive force?

Having never installed (or wanted to) a impact in residential systems, your pearl of wisdom is interesting. All impacts I've ever done were sports fields with solid swing joints.

I'm talking above-ground risers. Systems with 25 psi head pressure running from pond water are Maxipaw territory.

On a residential private well here. 30-50 pressure switch, but about 25-35 PSI at the head at 12-15 GPM. Impacts work well. Rotors tend to stall and/or clog.

I must live right; we have two cistern-fed sytems with no filters and the I-20s do well.
I do believe it's the high pressure we run to force the crap through the nozzles.

If it gets to the nozzle, it's getting too far.
