As far as I know, the pump is 4" in diameter. At least the well rep thinks so. All the pumps used in my well at the house over the years have been 4".
I think a little back story might help understand the condition of this well. The guy who owned the property before I bought it was a scrounger. He built a house on the acreage from things he hoarded and pulled from dumpsters. Garden hose in the walls for some of the plumbing, electrical wire spliced in the walls with no junction boxes, used, mismatched windows & doors etc..etc.
The bank eventually foreclosed and I was able to buy the place. The only thing worth saving was the barn. I tore the house down along with some ramshackle out buildings. I relocated the water & electric services to the barn. The worst thing I found when I demolished the house was the cinder block chimney he used for a coal stove. It had no tile liner and the cheap mortar he used on the block was falling out of the joints. There were scorch marks on the wood siding behind the chimney at almost every seam! Had I not demolished the place, it likely would have burned down on it's own.
Anyway, this guy got hold of some used well casing and paid a well guy he knew to dig the well and install it. When I dug out and exposed the casing to get at the pitless adapter, I found that the casing itself is badly corroded. That may be why the packer was installed. Everything this guy did was on the cheap. Who knows what the well guys will find when they get the camera down there. At this point, I'll be lucky if I can just reuse the hole.
