The Grundfos MQ is built for trouble-free operation. The PM1 starts the pump when the starting pressure is reached, and keeps running as long as there is flow. The PM1 15 is a pressure manager for use with the Grundfos JP5 and JP6 booster pumps,CM pumps and SQ 3" borehole pumps. A well water pump is a typical way of supplying water to the home. Downstream of the CSV1A pressure remains constant as long as demand is between the upper and lower limits of the valve. This is the video I sent her as to what to do next time it sticks.
