I take it a boiling tank is bad? Doesn't sound good ...
Grandpas cinder block getup lasted 60 years ... so I figure my setup should be good for 120. According to the neighbors, it was installed in the late 60's, so I'm all set in my lifetime.
No no no, when you open the tank it should be alive, sizzling, boiling, active... and hot or warm in the winter, enough to melt snow when its not too cold.. a septic system is a living thing. And it can be harmed in ways you would not think of..
Wash your dishes with anti bacterial soap ? not good , not good at all. Nope, if you have a septic system do some reading on maintaining it, you will be surprised on how many thing you are doing wrong.
Rule of thumb, if it does not come out of your body you don't want it in your tank. There are exceptions but thats the jist of it. One can disagree but it will come down to pay me now or pay me later.. no short cuts here. Read up and save your money down the road..
Oh and edit to add.. DON'T use any product like Rid Ex or anything that says it will help your system, It's snake oil.. Any state dept of health will tell you that if you look into septic system maintenance..
