I was picking up feed for my chickens last Tuesday and this old well driller was talking to the guy behind the counter. He said most people who drill a well don't test the water until after the pump is in and wired up. That blew my mind because if the water is bad you just wasted all that money. He said testing the water first costs about 75 bucks and saves you from a 3,000 dollar mistake. I took a card from him and I'm gonna call next week to test my neighbor's spring before I even think about digging my own. Anyone else test their water source before hooking everything up?
