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.
