The clog is usually due to the resident’s misuse of the system. In general, if a septic system backup occurs and then a clog is found that is cleared and the system begins working normally again, the system probably has not failed. If someone places foreign material or excessive toilet paper in the toilet, this could cause a septic backup flow that might continue to spill while water is introduced into the septic system from other sources in the house. A family of seven people can place an above normal demand on a septic system. In this case, the large amount of sewage backup indicates that the septic system might have failed. A sewage backup like this one could also be caused by a block in the septic tank outlet into the leach field. This can occur if there are flooding problems on the property.
#Etank system backup full
In cases where the water level is within a few inches from the top of the tank, ground water may enter through cracks in the tank over time and this may cause the tank to be full for many months even after it has been pumped dry. An environmental health specialist went to look at the septic system and determined that the septic system had failed.Ī normal septic system is an open system to the environment at its terminal end, the leach field. The homeowners had to leave the property because of this backup. The house had several other septic backups and during one of the backups, 500 to 700 gallons of sewage spilled from the downstairs toilet and shower into the hall and bedroom. The previous owner of the house agreed to pay for the costs of getting a licensed plumber if the septic system was found to need a new leach field, and possibly a replacement of its PEX pipe system. There was a certified clearance on the septic system but there were still plumbing problems that existed.

The purchase contract for the house included an addendum stating that the septic system in the house had been through numerous repairs due to blockage, which the sellers claimed had been a rat colony infestation of the septic tank that had been cleared out by Pest Control.

This case involves a homeowner who bought a house for a family of seven people and experienced two septic system backups before the close of the escrow and two septic system backups after the close of escrow.
