But the end result is the pump would stop and that what we would need regardless of not filling the tank completely , then the next time you open a faucet the pump would start again after consuming the little water in the tank .
I believe that at opening the faucet next time you would find the water present at the set shut off pressure which would be fine !
Why that "little run time " should be important for the pump while it has been running all the time during water usage prior to closing the faucet and the start of the struggle to fill the tank through that very small hole at 1gpm rate ?
How this small amount of water would cool the pump? what you mean by that? Do you mean that if the small hole is blocked the pump would heat up ? if that what you mean then of course I understand , but if you mean that that small amount of water would cool the pump in general then I dont understand what the original flow was doing to the pump during the normal water usage !
I would feel sorry for a 2HP pump to do that , wouldnt that make it heat up and eventually affect its age ?
I have used a device called Fluomac , you can have a look at it www.italtecnica.com without the need of a pressure tank but the result was that you would open the faucet and you would find almost no water or very weak pressure then suddenly the pump starts and you have a blast of water , that have created many terrible problems in water usage in the house specially if you have a guest who does not know that a flood would follow the few drops coming from the tap and keeps opening the tap more and more to have more water then suddenly spalshhhhhhhhhh lollll
I had to REMOVE that device and totally forget about its theory and return to the pressure tank / pressure switch combination after I thought that I would save the efforts of their maintenence from bladders , air pressure , regular cleaning of pressure switch hole which sometimes gets blocked hence pump keeps running although I fixed a pilot lamp in the kitchen which goes on when the pump is running so I could switch it off manually when I suspect abnormal running time .
