I'm considering installing a water-powered sump pump, and the
instructions include:

Pipeline restrictions
Pump should be teed-in before any devices that restrict water flow.
Examples of such devices a stop & waste valves, globe-type valves,
Pressure Regulator Valves (PRV), water conditioners, filters, etc. ...
Zone (RPZ) devices may reduce pumping rates significantly

What does it mean by stop & waste valves, globe-type valves, and
pressure regulator valves? Do I have them?

All I have between the street and where I plan to connect it are
1) an standard shut-off valve which is fully open.
2) a pressure-regulator, I think it is, but not afaik a pressure
regulator *valve*. I haven't seen this thing since I moved in 27
years ago and put a wardrobe in front of it, but it was small, only a
few inches from where the water pipe comes in the foundation wall, and
I think every home in the area has one, not to lower the pressure
below spec, but to keep it from going above spec.

The water flow is over 10 GPM, measured at a garden faucet. Doesn't
that imply that there aren't debilitating pipeline restrictions?
