We moved here 6 years ago and replaced our jet pump that year the pump went this summer and we replaced it again but since then we have been getting air bubbles in the line and we keep losing pressure every time the pump comes on , we have lots of water. Can someone please explain? Just where is a foot valve on a sandpoint well and how do you fix it?
