So, do you still think it needs to be cleaned every 3 years? I have heard of people going 15 years even with lousy systems. You can check by wrapping a stick in cotton cloth to at least the depth of your tank and dipping it….the sludge layer and the grease layer will show how deep they are on the cotton. I have to do that again soon but after 3 years it was not near to capacity with sludge or grease.
How big is the tank? Mine is 1,200 gallons. No filter. We don’t use the garbage disposal all scraps get composted, fed to animals or thrown in the trash.
