Septic Tank Inspection
Your septic tank needs to be inspected on a regular basis to be sure it is working properly and that all the elements of it are in good repair.
For septic systems that we did not install, we need to know the exact location of the tank. A sketch of the system is sometimes included with the original permit, and makes locating the tank much easier. When there is no sketch, a probe is used. Once located, the tank must be uncovered and opened for inspection of the insides of the tank and all its components.
The accepted maximum level of solids in the tank is 1/3 of the liquid depth; more than that means your tank is due for a pumping. And to get an accurate look at the inside of a tank, it should have been recently pumped (within 24 hours.) This allows the inspector to check that the tank is still watertight.
Other elements include baffles and tees, parts that help the solids settle in a quiet environment. Baffles and tees are connected to inlet and outlet pipes on the tank, and the inspector will check that connections have been assembled properly and show no corrosion or cracks. These elements can be replaced if they are faulty.
Inspection also looks at inlet and outlet pipes for water entering the empty tank. All water and plumbing fixtures within the home are out of use during the inspection, so water entering the tank may mean a leak somewhere within the home’s plumbing system. Water draining back into the tank may indicate a problem (usually a clog) in the drain field; this will most likely require further inspection into the drain field and repair work.
Effluent filters, located on the outlet side of the tanks, are also inspected to be sure that no solids carry over into the leach field.
If you do not have septic tank risers, we may suggest their installation. These plastic rises fit over the “manholes” on the top of the septic tank, and are installed to come to ground level. With risers in place, less excavation is needed for the next inspection. It is also easy to locate the septic tank and accesses it.
If your septic tank has risers, the inspector will check that the lids have no cracks and that they are secure.
