Hello. I recently purchased a piece of property in VT. I'm starting up a well that's been dormant for about 3 1/2 years due to the house burning down. I hooked it up to a generator to see if it functioned. It took a bit but I started to get some flow of water. It would flow for about 3-4 seconds and then stop for about 30 seconds. It would gen flow for about 3-4 seconds again. Also at the first the water was clear then it turned muddy. Any thoughts in this? Does the pump need to be replaced?
