What are Signs of a Failing Septic System?
Sewage backup into the home is one possible sign of a failing system. However, backup can also be simply the result of a blockage somewhere between the house and the septic tank (this is relatively easy to fix). Another possible sign of failure is a smell of sewage outside the house. If this smell is more noticeable after a lot of water has been put into the system – multiple showers or several loads of laundry (if the laundry waste discharges into the septic system), for example – this may be an indication that the drainfield is failing. The smell may also be accompanied by a “spongy” feeling in some areas of the drainfield or near the septic tank. The “spongy” feel may be caused by water and waste being pushed to or near ground level. If ponding water is also seen, this is called “breakthrough” and is an almost positive indication of failure of one or more parts of the system. This smell, however, can also originate at the plumbing vent. In either case, further investigation is warra
