Just bought another house and I'm trying to get the we'll going.
From research I've determined it's referred to as a deep well packer jet system. I have located the problem but have no clue how to repair.
If you're unfamiliar with this type of well there is a pipe inside the pipe you see, the inner pipe is what feeds the house, the outer is pressurized by the pump...not as simple as just replacing the tee.
So far I've not even determined what this part is called and I've been google ing all morning. I've got calls in to a couple of well contractors but have a feeling they're just going to want to still a new well.The local plumbing place (pretty knowledgeable) said 'good luck' finding the part, they didn't even know what to call it.
My first thought is to find a stick welder and see what I can do...
