What is a safe drain de-clogger for septic tanks?
I would use a plunger , Did you know there are drain openers and drain cleaners, One is for stop up drains and the other is for slow drains, Use the drains cleaner regularly once a month, the little bacteria muncher will clean your whole system and make it really hard to get a clog again, a plunger will get most clogs open, Just get the water rocking back and forth a few times and on the last draw go for a good pull, cover any vents up so you can get the max pressure going, remember rock the water and pull really hard on the last draw.
