Upfront Septic performed a Property Sale Inspection and Repair Service (RSS) at a property on Anderson Island, WA, to assess the condition of the existing septic system. The property has a 1,125-gallon, two-compartment septic tank. Upon arrival, our technicians excavated the tank to access the lids and inspect the system.
During the inspection, our team found root intrusion around all five septic tank lids, entering through gaps where the lids sit in place. The inlet lid was located beneath a rhododendron bush, making access more difficult. Technicians were able to remove the roots hanging into the tank from most access points, but the crossover lid could not be removed because its seal would not break. Removing the remaining roots in that area would require destroying the lid.
Additional root intrusion was found around both the mainline, which carries wastewater from the home into the tank, and the transport line, which carries wastewater toward the drainfield. The property's as-built drawing also indicates that a portion of the drainfield is located beneath the gravel driveway, an important consideration for future maintenance or repair work.
Recommended follow-up work includes installing three 24-inch risers and two 12-inch risers to improve access to all five tank openings, resealing the mainline and transport line connections, and removing the rhododendron bush to improve access to the inlet lid. The crossover lid will also require attention to address the remaining root intrusion.
Completing these recommended repairs can help reduce root entry, improve access for future septic maintenance, and address areas of concern identified during the property sale inspection.
