Is this possibly my septic pump out access?

4th home I’ve had with a septic, and the first that I can’t find the tank! The house is in NW NC mountains and is ~45 years old. When we bought we skipped the septic inspection as the previous owner had it pumped just a few months prior. That said, I have no record other than his statement. We have no issues, it’s just disconcerting not to know. The tank likely isn’t out much farther since there’s about a 20’ sharp drop off 18ft away from this. I’m almost wondering if they put the hot tub over it. This is the exit from the house, and when I open the cover, I can see when water flushes from the house. Seems to go downward about 45 deg from this point.

Where to install drain pipe

Where do I install the drain pipe for my RO system? Red line? Green line? Blue line? Or do I need extra plumbing work?

Is this normal for a Sump Pump

I was wondering is this type of wet venting acceptable for a WC in a district using IPC (Baltimore, MD) 10ft between Wc and LAV Tee. If Permitted what type of Tee should I use? Regular, Sanitary or wye?

Rheem Combi Boiler is Leaking and I’m trying to fix it, can I use Teflon tape between the inner joints?

I believe this area is where the heat exchanger dumps back into the hot water return. The left area with the heat sink is a female connector and the black plastic piece on the left is a male connector. This connector has 2 o rings to avoid leaks. I recently replaced the O rings and added Teflon tape on a similar connector pictured here in the center right of the picture where you see the rust. This connection stopped leaking, but now a new one formed on the red circle when I put this thing back together. This heater has been a bit of a nightmare ever since I bought the home. Need help and need to have this stop leaking once and for all.
