Performing a few repairs to a septic system in Twin Mountain NH. Correcting the sagging pipe that went from the house to the distribution box. Removed and replaced the failing distribution box with a new precast concrete distribution box. The new box was placed on a precast concrete pad to prevent settling in the future. Updated septic tank baffles to PVC baffles at the inlet and outlet ends of septic tanks to bring it to up to state code. The corrections made to this septic system were found during a septic inspection for a real estate transaction. Our video pipe camera that was used, allowed us to know that the pipe leaving the house had a sag in it.
