I'm at a friends house in Mexico for a while. They have a pressure tank with an AquaPak Pet PET13 / 1127 Jet Pump 1.3 hp bolted to the top of the pressure tank. There is an Evans AB-TMSP Compact Pressure Switch attached to the jet pump. The jet pump sucks water up from a 60' hole in the ground (well).
Here's the problem, when running hose off a bib that this setup feeds, if the hose is open fully, it pumps like normal. If you hold your thumb over the end of the hose, restricting the flow, the pump bounces up and down on the pressure tank like a bucking bronco.
Can anybody please explain to me why this is happening and how to remedy it?
