Basement bathroom rough-in plumbing, drain and vent layout - virtual. Also some basic plumbing rules.
The T which used for shower drain’s vent is not correct
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 🙏
name of this animation program can you give us the name sir
what program's is this?
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.
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
This plumber needs help. Not me, the guy who drew this. Read the codebook
Trap Arm on Laundry trap to short, its an "S" trap basically.
Lol wow I guess 🤦🏼😂🤣
What a stupid way to run a toilet line
loos looks shitty
Sorry check your horizontal venting fittings ????
Also short turn 90s on side is a no no ... who taught you should be slapped
You got san tees on back and san tee on vent for shower on back and backwards do us a favor and dont fucking plumb
I though the toilet couldn't flush past other fixtures?
If that's a SketchUp model, I'd love a copy of it. How can i get one?
Is that a sketchUp model? Can I get a copy?
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.
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
Lots of mistakes Don't learn from this design.
This video is more like find the mistakes. Do we get some gift for it? I've found 8 mistakes
Almost a great video BUT...it moves too fast to read clearly. Thanx
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.
Summary of rules in video: 1. Max distance from trap to vent: 2x pipe diameter in feet. 2. One horizontal drain 90 allowed before the trap. 3. Horizontal to vertical drop: Use a tee footing. 4. Horizontal to horizontal: Use a Y footing. 5. Vertical to horizontal drain: Use a Y footing, or a long turn 90, or a combo tee fitting. 6. ½ Inch water lines can supply three fixtures (e.g. single faucet vanity + water close + single valve tub) 7. ½ inch water lines tap off of ¾ or 1-inch lines with ½ inch pipe, to fixtures. 8. IF more than three fixtures, tap ¾ or 1-inch lines with ¾ inch. Then tap off ¾ to ½ to fixtures. 9. Full body showers require ¾ in supply to valves. 10. 3 or more toilets require a 4-inch drain pipe from the lowest toilet. 11. Shower drains can use 1 ½ drains pipes (convenient for tub to shower conversions). 12. Horizontal drains: Never go larger to smaller in downstream direction. 13. Never install drain or supply lines where they can free. 14. Sharkbite fittings will require planned access 15. Any trap that doesn’t have easy access needs to be a glue trap. 15.1. I think a glue trap is the one-piece PVC type trap (typically under floors and other inaccessible places) , as opposed to “union traps” (typically accessible under sinks).
All vent are wrong
Can you share this file? This is sketch Up, yes?
Vent tee’s are backwards
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
San tee is backwards

Wet venting, tees are backwards. Another thing, you can’t use a santee on its back. You’re suppose to use a combo
All the venting is wrong just saying
The venting is fine. Some of the fittings are wrong.
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
Why is the vent tee backwards?
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!
Really? Why the stupid music?
Am new I would I know to fix them
Done subscribe - sir/maam plz subscribe and support my channel - AutoCAD contents th-cam.com/channels/RgdELUzvBQmFfmF0djLufA.html
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?
@@alang8243 Yes, however I would always try and minimize changes in direction. So those 2 elbows equal 180 degrees of turn before joining the shower drain. Depending on where the walls were gong to go this may have been the best they could do but normally a little thought can limit the change in direction to less than 180. If a main sewer snake ever has to be run from this W/C location, it will make the job much easier, especially if it has to be run a long distance or cutting roots out front. Of course a clean out installation is always preferable but not always available.
@@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
Why would you run the toilet with two 90s? Why not just a 45 strait to main drain? Same with shower
You nailed it
the laundry sink and washing machine need to go through the back water valve
Mistake in shower vent T?Or no?
What software did you use to create this video?
It might be a sketchup built in feature
The san tee for vent needs to slope towards the waste line not the p trap
Thank you
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
Love the example. Nice job. Hate the music.
what is the music? so dope
45° bro
Toalet, vagyis WC 110 mm tehát 4 inch !
