Whole house sewer problem

Our house appears to be clogged at the main pipe or air vent. I was about to call the plumber, however, decided to give it another shot snaking outside vent and appears it fixed the issue, at least temporarily.

Symptoms: When taking a shower, kitchen sink gargles. Both toilets are very slow to flush. Waste disposal flushes all the crap into utility sink downstairs. When running utility sink, the washer drain gargles a couple feet away. I tried to snake from the basement access hole, but could not pull up anything. When I snaked from outside vent, some crap did come up, however, not as much as I would expect would clog a 3 inch pipe. I could not break loose the floor access holes, however, if experts suggest, I will give it my best. We have town sewer and they okey'ed on their end.

Questions: Could the air vent cause this issue? Is it even possible to clog it up with sewer? The reason why I zeroed in on the air vent is when I opened the smaller access hole, toilets started flushing.

Sounds to me like a classic venting issue. Either the system isn't vented properly or the vent is clogged.

I would give it a 95% chance that it's a clog in your main drain. Probably at the U-trap (those two cleanouts), or possibly beyond it. You can start snaking at the small cleanout on the vertical stack, but I think you're going to need to get into the U trap.

If you have a propane torch, heating the cap might help loosen the putty or whatever's locking it in.

Decided to go with pro after a few snaking attempts that only helped for a few days each time. It was expensive for a 10 minute worth of work, but live and learn....

If anyone in the future reading, to remove the cleanout caps simply chisel them out with a few love taps, then replace them with new for a few bucks. Forget wrenches, torch, heat gun etc. Obviously hit the caps, not the pipe. Start with the street side first! If you don't, you risk a poop flood in your home.

Street side of the trap was almost completely clogged. I may have only poked a little hole with my snaking efforts.

I love that second bathroom connection. That certainly wouldn't pass inspection.
It looks like it's leaking. That water running down will accelerate pipe rusting at the joints.

They all look like that, but i don't see any moisture. The nuts were loose on those clamps though.
