Frequently Asked Questions / Concern that a deep well can not provide adequate GPM using a CSV

« on: June 18, 2019, 11:47:40 AM »

Since the CSV will control the pump to provide a constant pressure of 50 psi , it seems that a DEEP well will have a limited capability to provide sufficient GPM under a high load like running sprinklers while taking a shower, and running a clothes washer. We were told when we bought our 60 year old house that the shallow well failed and was replaced by a "deep" well, but have no idea how "deep" it is.
    How can I determine the max GPM the "deep" well is capable of providing, and how many GPM would be required to provide water to a single sprinkler, shower, and washer at the same time?
   Thanks
