My husband has been a general contractor for thirtyfive years and has put in and fixed more septic systems than he'd like to remember !
How many of you when you clean dump your cleaning solutions down the drain or out the door ? As soon as he starts on a messed up septic s. he can tell you what cleaning product you favor, Pinesol, Mr. Clean, antibacterial soaps etc. He can also tell you if you have a garbage dispoal, or just dump "alittle grease" down your drain. Oh and he loves the little bleach tablets people use because the bleach works on the rubber washers and toliet stuff and he makes money fixing leaking toliets.
He has pulled out alot of stuff out of lines, pampers ,panty hose etc.
If you havn't had your septic tank pumped for years you already have a problem you just don't know it yet.
We worry about the bleach with bcg but don't give a thought to the bucket of pinesol we dump into the system.
I always dump cleaning water outside it keeps the peace in my house. lol
He said if the tanks pumped and you don't dump a bunch of other cleaning stuff in it you should be ok with the bleach. If it makes you feel better dump some ridx in it. Rocky
