Water pump (one more time)

[David Brady]

I also have the Shurflo Smart Sensor 5.7 65psi pump. My inlet
and outlet plumbing are long lengths of 3/4" ID tubing. The
connections to the pump are the Extreme Series Straight
fitting 3/4" quick connects, part number 94-615-04. These
fittings eliminate any elbows at both the inlet and
outlet of the pump. The trouble is, I still get pulsating and
hunting while the pump tries to zero in on the pressure and flow
required. Anyone else have this problem? It's worse on the
hot water than on the cold. I suspect an air pocket somewhere,
probably in my hot water heater. It gets better with time, but
by then, my fresh water tank is close to empty, it's time to fill
up, and the pulsating starts again. Again, I'm thinking an air
pocket.
