I recently moved into a new home and it seems like I am on this website too much for my pleasing even though I am thankful for the info provided. Anyway, I was mapping the location of my septic tanks before grading the yard and I pulled the lids off both tanks to take a look around and I noticed there are no baffles. Before I go to my builder I would like to know if there are septic systems like mine that don't require baffles. I have a basic gravity flow system that has two large cement septic tanks in series that drain into a drainfield. Unfortunately I think my builder will come up with some reason why they aren't needed to get around having to pay to have the tanks pumped and baffles installed. Also, when grading the yard can they put the weight of machinery on the septic tanks or should I rope the area off? Thank you for your time.

should there be in a blader type water tank..The tank is in a pump house with a 1/2 hp shallow well pump supplying the water. The house belonged to my deceased brother, and we are fixing it up a little...I don't know what size in gallons it is, but i did get the dimensions of the tank..16" high X 15" diameter..It is a blue tank, and on the side i can read Aqua- Air Water Tank, and the name "A O Smith". I can not find anything pertaining to how much the pressure should be.. I checked the pressure with the pump unplugged and and drained and its only about 5 lbs...I do not want to just start putting air in without gettig advice because i don't want to break the bladder....Also one more question,,Does the pump need to be completely level to work properly...Right now the pump is sitting on a stack of 8" cinder blocks about the hieght of the tank, and turned at about a 25 degree angle with the motor end pointing down, and the plastic pump housing pointing up...Thanks for all replies...
