I have a vent pipe coming out of the ground in my back yard. I believe it is a vent pipe. It is pvc pipe shaped like a candy cane. I have a pump up system, wastewater is pumped from the septic tank up to the leachfeild. The pipe goes straight down into the ground near the leach field. Could I relocate this pipe aprox 10 feet from where it is? Would this effect the system in anyway? I would dig down 2-3 feet and elbow it off with a gradual incline to where it would come out. Is this not recommended? What is this pipe for?
