I followed instrux to "...wrap cloth around a stick, mark 6", 1', 2', etc. to create your sludge stick. Drop it down, wiggle it around to make sure it's good and bottomed out though all the sludge." I followed the intrux to hold the stick in the tank for a minimum of 5 minutes before pulling it out. I would appreciate another opinion on what the sludge level is for our septic from this picture.
Also: what is the 26" manhole cover in the 2nd picture accessing (the primary chamber)? if so, where is the input baffle? The septic records say it's a 2 chamber tank. It's a gravity system ... probably 1150 gallons. The manhole cover is 109" from the house.
The small green lid leads to the output baffle which contains the filter. The 26" manhole cover doesn't seem to contain a baffle .... so where is the input baffle?
