Keith 3267 wrote It passed inspection in the past so it is grandfathered. I am going to be the dissenting voice
Be care full I am an old plumbing inspector and i never saw a code allowing a person to dump grey water into the ground. Also an item can only be grandfather if a permit was taken out for such work and the codes allowed it at that time. Also should you later touch that grandfathered item the you lose your grandfather ness and now must bring it up to code. A lot of communities now have very tough pollution laws so be carefull. Who is to say that after the house was built the owner hired a handy man to install a clothes washer drain and he took the path of least resistance just brought the pipe outside and buried it.
