A: Hi, David - Max of 30". One may purchase 1 or 2 manhole extensions that are 15" high. 2 of them will allow for a max burial depth.
A: Hi, Chris - It comes with tees and gaskets, but no aerator.
A: Hi, Bret - Yes, it's made for sewage and may be pumped so long as instructions are followed carefully. It is for below ground use only and must be installed per instructions.
A: You will be fine as long as these plastic tanks aren’t buried deep… I wouldn’t use these if you have to put more than 2 feet of dirt. The weight of the dirt will crush the tank. I seen it happen way too many times….
A: Hi, Rusty - If installed correctly, the tank will not do that. The installation instructions must be followed completely.
