My septic system is not gravity fed, but uses a pump to move the liquid up into my drain field. There is a J-Pipe vent at the pump end of the field, but there is also a 4" diameter pipe sticking out of the ground at the other end of the field.
This 4" diameter pipe is cracked and I need to replace it. If I dig it up, will I find that it's connected to piping underground or is it just inserted into the ground? It's only sticks up about 6" above grade....should the one I replace it with be higher?
Thanks very much for your help.
If the pipe is simply stuck in the ground, it won't be doing much for your septic system. Most probably it is connected using a Tee to the 4 inch piping in your field. Simply replace it with a similar sized plastic pipe. My pipe sticks up about 3 feet above grade, local practice varies.
I had the same thing. We have four laterals that originally had such a pipe at the end of each one. I asked the installer what they were for, and he said they were inspection points. He also said, off the record, that once my system was approved, I could get rid of them. I did.
