There's a shed built against one side of our house we'd like removed. Our problem is that inside the shed run two three-foot pipes out of the ground that are joined together with PVC connections. One is a supply line and the other leads to the rest of the house. These used to be hooked up to a water softener. Both pipes are galvanized iron and emerge from a concrete "curb" in the ground on the side of the house. I've crawled under the house and the pipes are inaccessable.
I'd like to join these two pipes closer to the ground so there will be less of an eyesore when the shed is removed. Being that the pipes themselves emerge from concrete, and the only threads I have to work with are three feet above the ground, how can this be done? Is there a tool that will thread the pipe in it's current location? If at all possible I'd like to do this myself.
Thanks in advance for any help.
