Two years ago, A Better Septic rejuvenated my septic system. Yesterday I had a toilet clog unexpectedly, so I went out and dug to check the cleanout for the black water relief.  That’s often where you find there’s a clog or a root growing into the system.  I saw standing water.  I unscrewed the cap and looked in the one white inspection port filter that raises above the back lawn, and saw a few inches of standing water.  I called A Better Septic and asked for info on cleaning the filter.  I learned it’s not as simple as the installer made it sound.  You have to dig up the drainfield and lift up the concrete top to access the filter.   They could not give me a price on doing that since it is a job they do only with other services.  I felt I was not told ahead of time the maintenance would be costly and not easily done by me.  I’m sure it’s just a misunderstanding and when John arrives today at 5:00pm, he will evaluate the situation and make a recommendation everyone will be happy with.  Later, a friend came by and within an hour we’d found there was indeed a paper clog, so the situation may have resolved itself.  My question now is: what and where exactly ARE these filters and how and when do I change/clean them and what would have happened to the paper clog had it gone through? Would it have ended up clogging the filter?  I’m sure John  will know the answers for me.  He comes highly recommended.
