Many times when inspecting old homes we find the septic has been replaced and relocated. Old sewer lines are often capped off or removed completely.
This inspection we observed the old sewer line going through the foundation which had somewhat of a cap on it but not completely. A few feet to the left we found another sewer line completely open. At this sewer line I could feel air coming through the pipe and it smelled like an old laundry trap, open drywell my guess.
This home was built in the early 1900s and in the early days the septic system was designed to use the tank for solids only and the grey water would bypass the tank and go directly to the drywell.
Our observations led us to believe the original septic system was not properly decommissioned, removed or filled in and could potentially pose a collapse hazard and further evaluation should be completed.
