@@azycray4801 Hey thanks for the info. I'm laying my drain lines out right now for a basement bathroom, and I have a similar pattern in order to get the vent under the wall. It flows to a BWV that connects to my main 4". That 4" line has a cleanout in a good location for "roto-rooting" in the future.
I was looking at the directions of those vent tee's.....and the laundry line needs to be below the utility sink drain on top of the shitz you said .. nice catch plummma
So the only T you people noticed that was backwards was on the drain system at the shower and not notice that all of the T's in the vent system is facing the wrong way of air flow!
Sanitary tees are not to be used on their back and the vent connection for the shower is installed backwards. Also some of the vent fittings are installed backwards
I'm glad someone is paying attention. Glad you picked up on the vent T orientations. Would you mind stating the correct usage when a DWV (Drain Waste Vent) T is used as a venting T, particularly in the horizontal drain line? In my state, the configurations shown for the venting Ts in the drain lines would normally be allowed, though, agreed with you, sloppy. The DWV vent T is used to pass air and allow in line condensate to drain. In my state, a vent T (looks like a squared T, vs one with a lead-in), on its back, is not allowed in the drain line. Must use a DWV fitting., as shown in the clip.
Journeyman plumber here and I saw all those backward Ts right away also, my master would flip his lid if I did this!! Huge mistake. Always keep in mind the direction of flow as to the direction of your fitting. I’ve made this mistake more than once, especially when you are working upside down and figured it standing up.
@@plumbinghelper7993 When venting fixtures below the flood rim drainage fittings must be used. In this example the sanitary tees must be replaced with combination wye/45 fittings for the shower and the toilet.
The santees are not are supposed to be there, you need combos with a long turn and the flow pointing to the direction of the grade downward flow of the main. Plus the toilets supposed to have a three inch vent stack and a clean out, then if the dfu's(drainage fixture units) allow reduce it to two inch above the clean out. The Santee's in the on the vent piping are pointing the wrong direction also. The flow of the sewer gas is supposed to point to the vent pipe end above the roof. This must be a point out what's wrong with this plumbing diagram video.
I wouldn’t use standard 90’s for the toilet flange, just Wye + 45 to the flange. I would typically set up a wet vent to avoid having to vent three separate fixtures.
But how can add a new shower drain to existing toilet drain on concrete slab ?? The cast iron pipe for the toilet come up from below so I need to cut before toilet flange but do I need to make a large hole / diameter??Thank you!
The mistakes are numerous. 1) toilet should wet vent shower and lavatory. (this would correct the other mistakes) 2) shower t-wye incorrect direction and a t-wye or santee is not a drainage fitting should be a wye. 3) toilet incorrect it 180 back on itself. 4) 1/4 bends on turns incorrect 5) 3x2 tee wye on its back incorrect for toilet 6) no cleanouts on 2 inch coming out ground 7) bushings should not be used but coupling reducers for servicing. 8) vent tees wrong direction 9) Washer box p trap too high off ground should be bewteen 6-12" inches 10) P trap too close to santee creates s trap. Should be twice the distance of the pipe being used 2" would be at least 4" pipe not hub to hub. 11) Washer box drain dumping on top of laundry tube drain not good practice for suds relief. 12) You cant wet vent these fixtures unless the drain pipe is 2 pipe sizes larger. The drain should be 3 inch then a 3x2 wye for the washer box, then a 2 inch santee on top of that serving laundry sink. 13) backwater valve should be on the main preferably outside and the access brought to grade.
1:29 Not enough horizontal pipe after P trap? I'm not a plumber but I've learned that there needs to be at least a length of pipe equivalent to double the pipe diameter after a P trap. Otherwise it can act like an S trap and siphon the water out of the trap and leave sewer gases inside.
this whole diagram violates several plumbing codes from both books. it should be deleted from youtube so noone gets taught the wrong way to do plumbing
i see two missing cleanouts and a very important missing vent, props to anyone who knows what im talking about. oh yeah and all those illegal fittings. edit: and on my way out i wondered if this room requires a floor drain, lolllllllllllll

Please don’t use this drawing!!!There are some major mistakes on it. Sanitary tees backwards, wet venting, sizing of pipe.
Agreed, this looks like a homeowner did it. Also the short turn elbows on the w/c horizontal.
@@azycray4801 Would the toilet horizontal drain layout be OK if the short turn 90's were long sweep 90's?

Horizontal to horizontal joints should always use some sort of long sweep.
Why would you run the toilet with two 90s? Why not just a 45 strait to main drain? Same with shower
You nailed it
If that's a SketchUp model, I'd love a copy of it. How can i get one?
But how can add a new shower drain to existing toilet drain on concrete slab ?? The cast iron pipe for the toilet come up from below so I need to cut before toilet flange but do I need to make a large hole / diameter??Thank you!
You need a jackhammer and a plumbing contractor
name of this animation program can you give us the name sir
Sorry check your horizontal venting fittings ????
what program's is this?
Mistake in shower vent T?Or no?
I though the toilet couldn't flush past other fixtures?
Thanks for sharing with us.
Could I install 2vent lines o 1 is enough. O is not allowed to add 1 extra in 1 circuit?
With a little thought I'm sure there is a way to horizontally wet vent this bathroom using the toilet vent for the shower vent and the lavatory drain
What software did you use to create this video?
It might be a sketchup built in feature
Wet venting, tees are backwards. Another thing, you can’t use a santee on its back. You’re suppose to use a combo
Why is the vent tee backwards?
Almost a great video BUT...it moves too fast to read clearly. Thanx
The mistakes are numerous.
1) toilet should wet vent shower and lavatory. (this would correct the other mistakes)
2) shower t-wye incorrect direction and a t-wye or santee is not a drainage fitting should be a wye.
3) toilet incorrect it 180 back on itself.
4) 1/4 bends on turns incorrect
5) 3x2 tee wye on its back incorrect for toilet
6) no cleanouts on 2 inch coming out ground
7) bushings should not be used but coupling reducers for servicing.
8) vent tees wrong direction
9) Washer box p trap too high off ground should be bewteen 6-12" inches
10) P trap too close to santee creates s trap. Should be twice the distance of the pipe being used 2" would be at least 4" pipe not hub to hub.
11) Washer box drain dumping on top of laundry tube drain not good practice for suds relief.

Does the laundry sink need a p-trap? I didn't see one. Thanks for the video .... this info never gets old !!!
Laundry sink will have a P-trap once you install the actual sink!
It has a bag trap like a kitchen sink or a lavatory sink
What software did you use to mock up?
Sketchup
Can you share this file? This is sketch Up, yes?
The sanitary tee coming off the shower, for the vent, should be flipped around. You should always flow down hill.
yep and a few of the upper ones were backwards as well.
Vent tees backwards, and the shower back vent tee is backward, also the vent leaving the roof has to be 3" not 2. Don't rough in like this plz 🙏
The T which used for shower drain’s vent is not correct
Trap Arm on Laundry trap to short, its an "S" trap basically.

This is the way it should be shown 1 2 3. If you don't understand this. Don't try this because you're a dangerous
This is super excellent....can you do an electrical like this?
plumber spfld il, well done video
This video is more like find the mistakes. Do we get some gift for it? I've found 8 mistakes
The san tee for vent needs to slope towards the waste line not the p trap
Thank you
This plumber needs help. Not me, the guy who drew this. Read the codebook
Great! Thank you
what is the music? so dope
So dope, it's retarded.
cool diagram thank you!
❤
the laundry sink and washing machine need to go through the back water valve
i see two missing cleanouts and a very important missing vent, props to anyone who knows what im talking about. oh yeah and all those illegal fittings.
edit: and on my way out i wondered if this room requires a floor drain, lolllllllllllll
Vent tee’s are backwards
Toalet, vagyis WC 110 mm tehát 4 inch !
45° bro
the vent t's are going the wrong way. look when he shows the top of the vent that is supposed to go out the roof.
The 2 inch vent for the shower is backwards as well.this is a bull shit video
All vent are wrong
San tee is backwards
Also short turn 90s on side is a no no ... who taught you should be slapped
Lol wow I guess 🤦🏼😂🤣
All the venting is wrong just saying
yep
The venting is fine. Some of the fittings are wrong.
Yes all San tee's are in backwards in the venting.
Really? Why the stupid music?
Am new I would I know to fix them
Lots of mistakes
Don't learn from this design.
What a stupid way to run a toilet line
Way wrong on many levels
THis video tells me nothing at all.
