Hi - hope your product can help. My septic system is aprox. 34 years old and am now seeing sewage water on grass at field area ( at low point of field aprox. 3 ft.. round area). I pump my system every two years ( three people living in house) I contacted a service company and was told a new field would be needed. My water softener also dumps into septic tank (once a week). What part does solar salt ( used for softener regen.) play in proper operation of septic systems. Should I disconnect the softener for now. I was told that 34 years is more than the system should last in my area and that additives are of no use at this point.
