4:20 hehe

Thanks for a great video. Are you planning to do a video on how to size water lines for fixtures in a house?

Mine looks way different than that! Probably why mine shuts off after about 6min of running. Thank you for explaining in a way I understand, I realize now to add check valves to mine and put a low flow. Thanks again!

Another great video from you! Thank you for describing this so thoroughly at a quick pace that lets me share your vids and use them to plan my plumbing fixes. Just wanted you to know that I appreciate what you're doing here and that your videos let me put ideas into action

I agree you say more in 4 minutes than others say in an hour! I understand exactly what you mean! Your videos changed my life (good plumbing is life changing!), I've replaced iron with PVC on 2 of my sinks so far--thank you!

Thank you - AAV knowledge increased!!

Love this! Appreciate it

That was incredible

That’s a terrible topology if those are the actual fixture locations. The toilet should be on a tee, and tub/shower and sink should join upstream of the toilet.

Great video, very informative for us DIYers.

Well I have a drain problem I can't figure out. I have a hundred year old house, balloon framed, and plumbing was added after it was built. Old plumbing. I have a bathtub upstairs that drains slowly unless I put a drinking straw in the drain as it is draining, then the draining speeds up, flowing much more freely, so I believe I have a venting problem. There is a 4" soil / vent stack nearby that goes through the roof. Where is my blockage? I've tried snaking the tub drain but I don't get very far. I believe the plumbing must make some sharp turns or something, so no luck there. If I put a garden hose into the vent / soil stack from on top of the roof, all that water flows find, out to the street. So where is my vent blockage or lack of adequate venting? If my vent begins where the tub drain meets the soil / vent stack and goes up, well that should never get blocked but if it did, the vent / soil stack wouldn't be able to handle all a water hose could give it, but it does. I don't get it. I don't know what to try next. To access the plumbing, I would have to cut an access hole through the wall and maybe do some more cutting in the floor once I look inside, as there is a build out around the old cast iron tub which has tile on it. I don't know what to try next.

I'm wondering about this "pressure" test. The test sample is completely filled with water, no air pockets. Pressure is applied and then the valve is closed. Supposedly you cannot compress a liquid (at least at typical water pressures). So when the valve is closed, is there really any pressure in the test sample? Just wondering...

Mines coming out the wall and it needs to rotate 90° and I cant do it because it will "S" the pipes and not drain properly

Made it clear to a complete novice why the necessity of a vent, the simple straw was a perfect answer as to the mechanics of the air-water function. Than you

What about ventilation for the toilet and sink and tub drain

That explanation is about as good as it gets. Thanks

That's undersized for wet venting

Thank you so much. Amazing explanation with ZERO wasted time.

Great job. Now use a pencil instead so you look less like a hack

Great explanation

I'm in Europe trying to fix a botched plumbing job by a Portuguese plumber. Not only was this video extremely helpful but it let me know there's options here in Europe. Thanks so much! Can you include the name of the company in your video description?

How do you know exactly where to put everything in these situations? Maybe a video in the future measuring/laying it out?

Looks like you and I will be plumbing my house together. 4min at a time, PERFECT!!!!!!!!

No dont need both drains,knockout is for choice of drain

Love it 🎸🎶🥁🔊

Thanks for the information.

That's atrocious

Fittings under slab is no good man, might be acceptable to manufacturer, but not good practice.

That's atrocious

He can't plumb He can't fit But the porta potty man sure knows his chit

I don't know what code book your using. You can't flat wet vent . It look like a combination system . But your sizing would be wrong . We must do stuff differnt in Los Angeles .

I'd rather see you finish that drywall first. 😂

Great video, straight to the point. Thank you!

Pretty sure the code states each fixture needs to tie into the wet vent individually, i don't believe how you have that set up is legal. You'd need a separate wye to go to the lav after the first wye where you pick up the tub for that to be a proper set up.

❤😮❤ Jeffery ? Question it appears my vent pipe is clogged up? Running 2 gallon water of water down drain down My lavatory drain causes my toilet to bubble then siphoned till sucks empty. The toilet wont flush normally I have to pour water down lavatory drain to get the toilet to siphon empty? ❤😮❤ Is it ok to put a clean out with a screw cap Wye pipe on the toilet 3 inch vent black PVC pipe .lowes has It in the white PVC. ? What is the code?

Very informative. Thanks

In Toronto Ontario we have the same requirement by code but ours says its a minimum of 1.5m which is about 5' (We use both metric and imperial.) Interesting how the values differ from one place to another yet are done for the same reason.

Great video. When are you finishing your garage?

you failed . Rule number 1 is never have a commode at the end of your gut line, it is to branch off of the gut line so that a sewer snake cant go up stream and into the toilet to and cause it to break and flood the structure

👍👊

I like this video

@ 0:20 the code says : The waste from an automatic clothes washer shall connect to a vertical drain of not less than 2 inches in diameter, or a horizontal drain of not less than 3 inches in diameter. IMO since you have a vertical drain (2 in diam.) that 3 in diam horizontal section does not apply.

You have to check local codes because I have plumbed in 5 states and this would not be code in any of them

what do you mean by the center outlet of the drain line is within 12 inches of the floor plane? I am installing a toilet and have only 2x8 to deal with and am about 4 ft from the vertical drain line going down from the second floor.

Been searching for videos on the operating mechanics of the actual systems, this was very helpful. Especially compared to other videos.

"Some plumbers think that other plumbers who use them shouldn't even have air to breathe". HILARIOUS!!!

But that 2” vent is also venting the 2” drain. Plus where is the tub and/or shower?

Does that 90⁰ 2" elbow directly below the vanity that drains from vertical to horizontal need to be long sweep, or can regular be used?

I'm still new to this, is that a sweeping 90 or street?

This was beauty man. I appreciate how clean and condensed you video was.
