The video shows the operation starting at the 4 minute mark. Check it out.
My Florida home has a shallow well, 2HP, 3 stage, high pressure water pump and good sized expansion tank. Even so, the pump would cycle all the time during showers and during moderate water use.
I learned about "Cycle Stop Valves" and installed one.
Analogy: It throttles the water pump, in much the same way an automobile engine is throttled. Rather than drive down the road by full power/coast/full power/coast cycles. It throttles the output and maintains a set, specified, pressure. In my case, 87PSI.
This prevents the pump from constantly cycling on/off/on/off during modest water use. During any water use, from a single faucet, to all six shower heads, pressure is maintained and the pump remains on.
Interestingly, the electrical draw is much lower, with low flow rates. Electrical draw goes from 10 A, down to 3.5 A at low flow. While I make no claims of energy savings, running the pump at low loads is not consuming as much as during high flow.
A 2HP, high pressure well pump is hard on "pump switches" and fries the contacts quickly. As most switches are for smaller pumps. So this is an interesting solution.
Better yet, my water pressure remains perfectly constant without the constant cycling during a shower. I'm very happy with it. I hope that the reduced flow rate drags up less sand from my well too. Time will tell.
I hope it lasts. They are supposed to be trouble free.
