A septic inspection checks the tank, the drain field and the system's records. EPA recommends having one done by a septic service provider before you buy, and Riverside County has its own certification form.
EPA's homebuyer guide lists what an inspector should look at:
The county's Certification of Existing Subsurface Disposal System form is signed by the person who examined the system. It records the tank capacity, the leach line area or the number and size of seepage pits, and the number of bedrooms and fixture units. It also asks about the tank material, whether the inlet and outlet tees are present, whether there is an effluent filter, and whether the distribution box is level.
Several questions ask what the inspector saw while pumping the tank, such as whether effluent flowed back into the tank from the absorption system and whether the liquid level was above the outlet tee. The form also asks whether sewer is within 200 feet of the structure and abuts the property line. The signer states an opinion that the system is in good working order or lists the repairs needed, and certifies it under penalty of perjury.
On its septic page, the county says a certification signed by a registered Qualified Service Provider is needed when you apply for a permit to repair or modify an existing system. That page does not describe the form as a sale requirement, so ask your agent or lender whether one is expected.
Alternative treatment units installed in Riverside County need an annual operating permit from the county. Under Ordinance 650, new owners must transfer the operating permit into their names within 60 days of a change of ownership. Ask the seller whether the home has one.
EPA suggests requesting the system's as-built drawing from the local health department, looking for lids or manhole covers, and asking the seller or agent. Also confirm with the county or your city which agency holds the file for your address.
Hire a licensed septic inspector before the inspection contingency ends, not after closing.
The form is signed by a contractor with a license number and a pumper company. The county says certifications must be done by a registered Qualified Service Provider or a Professional of Record.
EPA's homebuyer guide gives an average lifespan of 15 to 40 years, and says it can be longer with good maintenance.
EPA says inspections may be required by your local or state government or by your mortgage lender. Ask your lender early.
No. EPA says a typical household system should be inspected at least every three years, and pumped every three to five years.
