Normally I would use a water Jetter 1,250 PSI -2,200 PSI and a flow rate around 2 gpm-- just enough volume to flush away the debris and enough pressure to scour the lines to remove built up scale deposits.
Put a tee in your pipe to the right or left of box then out of the side of the tee go over under box and put a p-trap in and go up into box then out of the top of your tee go up and out of roof for vent
Yes. The toilet HAS to be wet vented within FIVE feet with the pipes from the sink and/or tub/shower.
To vent off odors emanating from the septic/sewer system and to allow the toilet to flush correctly and the other drains to empty correctly.
Yes, it does
The Fresh Air Inlet (FAI) is where the venting system starts as it draws the colder air into the system and allows it to vent through the vent terminal
Provide air flow to or from drainage system and to protect trap seals from siphonage and backpressure.
pit toilets are like portapotties that have a hole that has plumbing but isn't done very frequently a flush toilet has a bowl that flushes the waste when wanted using a plumbing system
A auto vent
I don't quite get what you mean. -A vent pipe in a plumbing system is usually 1 1/2 inch ABS pipe and may extend through the roof, or may end in a AAV under a countertop.
Yes BUT not an outside wall
Yes. The roof vent is usally located on the roof. If the vent is clogged, it can create numerous issues and prevent your plumbing system from working properly.
Your vent pipe for that part of the plumbing is either blocked or non-existent. Having to tip the toilet off center slightly is letting air enter into the system, something that should be happening under normal conditions if the vent pipe were working properly. That vent pipe needs to be snaked out and cleaned.
Vent - Cold Water Supply - Drainage - hot water supply /return
yes,
