[email protected] if there are wet spots on the surface above your septic tank, then either the leach field is failing, or there is a clog in the outlet of the septic tank. Most septic system regulatory agencies require that the septic tank be pumped, and inspected when the property is to be sold. Check with that agency in your jurisdiction, and inquire as to whether this inspection was completed on your system.
In Larimer County, Colorado, the Health Department requires the septic tank pumpers to submit an inspection report to them which describes the condition of the system after it has been pumped and inspected. Many mortgage loan companies also require septic system inspections prior to providing financing.
If the Health Department has no record of this inspection, then check with the local septic tank pumpers in your area to see if they have any record of pumping the septic tank at your address. JWA
