I just moved into a house on 5 acres in Palm Beach Gardens Fl

Well water was a bit brown so I called a guy out, he cheerfully charged me $400 to rebed my filter and something else which I did not understand, plus refill the salt, water is still brown so not sure what he did

anyway main problem I have is that there is a hose that runs from my water treatment tanks that seem to be pumping water many times a day, the yard is waterlogged and not sure how to stop this from pumping every hour or so for random amounts of time

I would welcome any advice, if I need to change any of the equipment, I will, just want a point before I call someone and get ripped off again
