There is a lot more to a septic inspection then just pumping the tank and checking a pipe or two with a camera. In fact, pumping the tank should never be performed prior to the inspection.
There are many steps involved in a proper evaluation. To start we have to scope the pipe from the house and locate the tank. We take the covers off and inspect both the inlet and outlet baffles. We also remove the cover for the tank to evaluate the sludge. This allows us to determine how well the system has been maintained and the quality of the bacteria. This is vital for the health and longevity of the system.
Next we scope the pipe from the outlet of the tank to the distribution box. We remove the cover, evaluate the box, and scope each line going into the leaching/drain field.
Lastly, we dig up a soil sample in the field. This allows us to determine the how well the field is percolating and if the system is functioning properly or in failure.
We will even do a dye test to show you a step by step on how the system functions.
We also check:
# of bathrooms/bedrooms and if the system is sized properly
Type and Quality of the pipes
Filtration backwash systems draining into the system
MUCH MUCH MORE!!!
Does the home you are purchasing have a community/public sewer system? Did you know it is the home owners responsibility to maintain and repair any issues in the sewer line between the house and the connection at the street? Many home owners don't realize this until it is too late and find themselves spending hundreds or thousands of dollars for unexpected repairs.
Just like the home inspection you are in the middle of a very important part of the process to purchasing your new home. You are learning about the home and if there are any safety issues or major deficiencies. These items can incur costs that you may need to plan for or negotiate in the price.
When performing a sewer scope we are looking for the following problems:
Roots growing through the pipes
Crushed, cracked, or collapsed pipes
Low points that cause standing water
Improper transitioning into smaller pipes
Loose, broken, or improper joints and connections
