I have a well with no known information. My best guess is it is relatively shallow, and only produces around 5gpm. On the other hand I think I have a 2hp sump pump (uses 1550 watts running) and that can push out over 13gpm, quickly draining the well.
Obviously my pump is oversized, and I want to reduce the max output in case somebody leaves the water running. I do not need more than 5gpm. Also, I only have a 20 gallon pressure tank with 4.4 gallons of draw down (30/60 PSI) and it fills up in less than 20 seconds causing excessive cycling.
1. Can I use a low cost VFD to slow the existing pump down to a more reasonable rate? I can get a 3hp rated VFD on Amazon for about a hundred bucks.
2. Should I use a valve instead to choke down the flow of the pump?
3. Can I/should I increase the pressure to hold more in the tank?
Which option would be easier on the pump? I feel like if I used a VFD to reduce the power of the pump, the motor will last longer than a valve causing higher back pressure. Am I wrong? I don't want to spend the extra money for a constant pressure system, just want the pump to more closely match the actual yield.
