I have converted my house to County water and now want to use my well for irrigation and filling my pond. However, I am not getting enough water from the well.
The details: Well is 15 years old, drilled 65' pump set at 54', 6" galvanized casing, 4" pvc casing inside 6" casing, 1" pvc downpipe to submersible pump inside 4" pvc, original draw 20-25 gpm per well drilling report.
Static level 29', I can draw 5.5 gpm continuously and the level will drop to 49'. when I stop the pump the well will recover to 29' within 10 minutes.
I suspect there is a restriction but I don't know the purpose of the 4" pvc inside the 6" casing. What can I do?
