2inch shower w trap into floor 3 inch w toilet

[Kingzucka]

I put in a 2 inch waste shower drain, into my 3 inch floor toilet pvc and i put a trap in. I post my stuff on youtube and someone said I would have an issue with that shower drain....since it has a trap and shower drain is higher than the toilet I wouldn't think so, but could this be an issue that the 2 inch going in is towards the bottom of the 3 inch ground pipe....I wouldn't think the pressure of the toilet would be an issue but in hind sight would the toilet water push into that drain...i wouldn't think so the water would keep running down the 3 inch waste line.

Is he right can the 2 inch coming in not go into the bottom, should I loop the trap the whole way around the 3 inch pipe so it goes in the top of the waste line and not the bottom?

below is a pic in case it doesn't stick:

the shower drain and that line out is a waste line, the fernco goes to sewer and the 3 inch pvc is the new toilet location
Your feedback Greatly Appreciated!!! Tried to hire my plumber he said what I wanted was too much work LOL, it is lots of respect to you guys!

Totally wrong everything almost, the 3x2 santee is wrong fitting , backwards and cannot be rolled down. that's a lot wrong.
what the heck is the 2 inch santee for? I don't know either but it cant be there. gotta think about how the shower is vented

plumbing code condensed: Every fixture needs a trap. Every trap needs a vent. Drainage fittings are installed so that shit rolls downhill.

If you can make horizontal wet venting work would be the simplest way where you can combine the vent of the toilet to use the Vertical take off of the shower vent. But the shower trap needs a vent that takes off vertically from the horizontal drain between the trap arm and the 3" drain.

Thanks the 2 inch is the shower drain and the 2 " tee goes to a slop sink in the garage, there is a 3 inch vent within 2 feet downstream which I thought would cover the venting. Yea that 3 inch Tee needs flipped around can't believe i did that but if it drain tests good, it will probably not cause an issue right? Also I can vent that slop sink separately wouldn't that take care of the shower venting?, slop sink is only 3 ft away.

The tee needs to be a Wye at minimum. The slop sink should drain separately into the 3" (no double trapping fixtures)

"Tried to hire my plumber he said what I wanted was too much work LOL"

When I say this, it's usually in conjunction with "for the price you want to pay", your YouTube channel is loaded with DIY plumbing.

That said, the 3x2" tee-wye is a no-go, has to be a wye, you also need a vent between toilet and shower, and there should be a separate 3x2" wye for the slop sink downstream of shower unless using as a wetvent - which is only allowed in one state, mine, not a 2"tee-wye, when you drain the full sink it will backflow into the shower and it also means your sink is double trapped as Tuttle points out.

Thank you!

The all rubber coupling should be a cast iron to plastic one with a metal shield.

The all rubber coupling should be a cast iron to plastic one with a metal shield.

Looks like it's getting buried; the all rubber ones are rated for direct burial (e.g. Fernco Standard Flexible Coupling). The 2" long metal shielded ones aren't rated for direct burial, they are for indoor use only (e.g. Fernco Proflex).

If you want a metal shield on your direct burial coupling, you can get that style. They are still 4" long, but they have a shorter shield and use two hose clamps per end (e.g. Fernco Strongback RC).

Cheers, Wayne

When you put a wye in though you can't point it down keep wye level so trap arm has minimal fall and use a ptrap and put another wye or combi in to pick up the sink your adding run a vent or AAV for sink

hey im almost ready to give it another go, tough questions:
Toilet to vent distance I saw 5ft, is that good, if not can my toilet vent be just a 1"1/2" vent?
In that pic, switched to a Wye for the shower and sink to come off, can the sink vent be good enough for the shower?
There is also big 3" old toilet vent right there in 1.5 ft so I wouldn't think an issue.
The future me thanks you many times over for not having to rip out my shower pan and redo this...the current me is still pissed for the extra work because water doesn't just go down the hole the way my brain thinks it should.
