I just had to have the septic guys out because water was backing up. Not good. Caught it in time, though, and popped the cap, and let about ten gallons run into the pasture and lower the water level.
Solids were about four inches thick. Good. But tank was flooded, so there's something going on with the field. I think it has to do with overwatering the grass, something SWMBO wants done JUST THIS WAY, GODDAMMIT!
This company is known as the best in the region, and if they say it, that's pretty much what it is. I shall share some things:
Never use a garbage disposal on a septic system. The foods decompose differently than sewage and give off H2S gas which eats concrete.
Never use any additive. If the system is working right, it is a waste of money.
Use phosphate free detergents, and don't do several big loads in a row, but space them out.
I'll watch the tank now to see what it does once it is full, and give the leach field a chance to dry out and catch up. If it still floods, then it is time for a new leach field. Oh, gee, I can't wait! The smell usually only lasts a year.
