Septic system question

[tynyphil]

I am installing RV hookups at my 'hideout'.......myself. I am using a plastic Septic tank and the Chamber type lateral. Have watched a lot of Youtube stuff but have never seen anything as to the height of pipe entering and leaving the tank ( same height or is the exit slighly lower than the inlet ?). I will be using 4" PVC 'Ys" as baffles inside the tank but have never seen anything as to how far down inside the tank to put the verticle portion of the baffle.

I would think you want your inlet much higher than the exit but I’m not a plumber.

Outlet 3" below inlet is all I've ever seen.

I’m not a plumber either, but my outlet is MUCH lower than my inlet. Nevermind, you were talking about septic systems.

Typically you want the exit pipe to be in the top of the "clear water" area under the "scum layer." You also want the lateral lines to have a slight incline downhill. The lateral lines should not be buried any deeper than they have to be to fit everything underground.
