Found an unknown pipe in the front yard when do the inspection. The seller said they doesn't know what it is. It's been there for 15 years since the house was constructed. Asked township, the township engineer is not sure too. It's not related to sprinkler system.
Is it a gas pipe? should I call gas company PSEG to take a look?
