The inlet pipe enters the tank perhaps 6 inches below the very top edge of the tank (top edge of the tank to top edge of the inlet hole) and is about 4 inches in diameter. So the bottom of the septic tank inlet opening (and outlet opening) in our theoretical example is about 10 inches from the top of the tank.
Where is the outflow on a septic tank?
This outflow pipe is normally at a lower level than the inflow pipe and at the far end of the tank from the inflow pipe, to ensure that only processed sewage is released. Many septic tank designs include baffles or multiple chambers to force the black water through maximum processing prior to release to drain field.

What is a septic outlet baffle?
The outlet baffle directs the flow of effluent from the tank to the drainfield; it prevents the scum layer from exiting straight into the outlet pipe and causing drainfield clogs and premature system failure.
How does a septic tank outlet baffle work?
A septic tank should have baffles at both the inlet and outlet. The purpose of the inlet baffle is twofold: to direct flow from the house sewer downward into the tank to create a longer detention time for the sewage to allow settling of solids, and to keep the floating scum layer from plugging the inlet pipe.

Odors around the drainfield might be due to loss of the gas-baffle in the septic tank. Of course such odors may also be due to a failing drainfield, so further diagnosis is in order.
Why do septic tanks have baffles?
Septic tanks may come with a baffle to prevent scum from clogging the inlet or outlet piping and septic fields. In some designs the septic tank inlet baffle or tee also reduces the movement of sewer gases out of the tank and up into the building through an un-trapped sewer pipe.
Where is the baffle located in a septic tank?
Located on the septic tank's outlet end where the tank is connected to piping intended to conduct clarified septic effluent to the absorption system (drainfield), the septic tank baffle or tee, also called a Gas Baffle in some literature or regulations, keeps solid waste and gas bubbles away from the septic tank outlet, thereby reducing the carry over of solid particles from the septic tank.
Can a female tee fit in a male septic tank?

How to tell if a D box is leaking?
Large pieces of solids, or t.p. etc. in the d-box can mean that either the outlet tee is missing or that too much water is flowing into the tank, either because of a plumbing leak in the house or a leak in the tank allowing groundwater into the tank. But getting the tank pumped every few years and having the pumper check the condition of the tank and the d-box is will be more useful.
How does a drainfield tank work?
The way the tank works is that the flow of sewage through it is slow enough for most of the solids to settle to the bottom (sludege layer) and the grease and other light constituents to float to the top (scum layer), leaving a liquid layer in the middle. As the grease and solids accumulate, the liquid volume gets smaller, and the flow rate through the tank gets faster, so that more of the suspended solids leave the tank with the effluent. That's why the tank needs to be pumped periodically. Small amounts of solids can be broken down by soil organisms in the drainfield.
How long should I pump a floatsom?
I am not familiar with the details of the way you describe this, so I won't comment there, but the recommended pumping schedule around here is 1-2 years. I pump ever two years in general and that works. I went three years once and had a LOT more floatsom by then.

Why are tees placed in septic tanks?
Tees were placed at the inlet and outlet to force incoming waste to the bottom of the tank and to prevent the scum layer at the top, which contains greases, oils and other lighter-than-water contaminants from flowing out to the drain field and clogging the soil.
How to glue a pipe to a tee?
If the slope is gentle enough, you can glue the pipes directly to the tee, but if the slope is steep, it's a good idea to glue a 22 1/2-degree bend onto the tee to make the glue connection watertight. If needed, the bend faces upward on the inlet side and downward on the outlet side.
Do you need adhesive for a septic tank?
The inlet and outlet holes are predrilled or, in the case of concrete tanks, preformed, and they are usually sized to hold a 4-inch tee tightly. You don't always need adhesive, but it isn't a bad idea to use some anyway, ...
