Any comments, does this look good

Toilet does not look like it has a legal vent if vented at all. Depending what is on stack with clean out it could be considered a wet vent but in my code area horizontal branch with toilet on it must be vented. Check with someone that knows code in your area. Waste from stack with cleanout could pull water from trap on toilet.

Dennm69 · Dec 19, 2011, 05:58 PM

The pipe running into the clean out is from the kitchen above, what do you Recommend, should I run it straight into the 3" or run it between the lav and the shower

Hi Dennm

Yeah, as Puffmugs suggested, you can't wet vent a toilet using a kitchen sink drain from above, for sure.

I have even more bad news, too... *UGH*. You CANNOT use sanitary tee fittings on the horizontal as you have for the toilet and the base of the stack. Here, you must have a wye fitting for the toilet (and a new 2" vent), and a long sweep elbow or combination wye/45 at the base of the stack. If you review your other thread I kinda mentioned that, but it must not have been crystal clear or you would not have done it, right?

The 2" elbow coming out of the ground that picks up the washing machine drain also needs to be changed to a LONG SWEEP ELBOW, and if possible, add a 2" cleanout here, too. Technically speaking, your washing machine ptrap needs to be closer to the vent (no more than 5-6 ft max.).

Anyway, your work looks real good and all will work fine, but in asking a licensed plumber I have to say that you have a few "illegal" things going on here... ;)

Glad to discuss more if you want, OK?

Can I bring that kitchen drain straight down to the 3" right after the checkvalve,The other changes Im on it

puffmugs · Dec 19, 2011, 10:20 PM

What I would recommend put a 3x2 wye on it's back before toilet branch wye and run that up for kitchen sink waste, elimate 3" vertical pipe going up to kitchen sink waste, Put a 3" wye on horizontal main run and off the 3" branch to the toilet put a 3x2 wye between main and toilet and run 2" over to lav sink to wet vent toilet. As Tom says your washing machine stand pipe is too far from vent. As Tom says your system may work, but there are things that are not legal.

massplumber2008 · Dec 20, 2011, 05:49 AM

If this was me and I was trying to keep as much of the work you did, I would cap the 2" wye feeding the sink and use that pipe as the vent for the toilet....means the 3" sanitary tee at the base of the stack can stay now! This 3" reduced to 2" will now act as the toilet vent... ;)

Then, simply connect into the 3" drain AFTER the check valve for the kitchen sink (via wye fitting) and connect the toilet via a wye fitting and you are all up to code.

You CANNOT wet vent the toilet using the bath sink drain/vent as that would require you to rip out all your work as a wet vent connection into a toilet drain needs to roll above the centerline of the drain...not at centerline, but above center line...and since we can avoid that and still end up with a satisfactory job I'd stay simple and go as I suggest, OK?

If you can add 2" cleanouts to the bath sink drain, the washer drain and the new kitchen sink drain you will be all up to code (don't forget the long sweep elbow at the washing machine drain).

Sorry Mark as referring to you as Tom, and not to confuse Dennm69 as your recommendations on how to make his job legal are very good, but as a point, code is different in different areas and in this area you CAN wet vent a toilet with a lav waste by placing a 3x2 wye between main and toilet opening laying the wye turned up with only 1/4" pitch until it turns to the vertical. This is the only legal way to wet venting a toilet without running a individual vent here. At the point Dennm69 is, your recommendation seems to make good sense for him.

massplumber2008 · Dec 20, 2011, 05:38 PM

There goes that darn "codes differ by state" thing again... ;)

I was almost sure that all states required the rolling of the fitting above centerline, but good to know that some still allow a "1/4"pitched fitting" so I can present the best answers possible! Thank you for pointing it out! Always appreciate your input!

Dennm69 · Dec 27, 2011, 12:44 PM

Is this OK

puffmugs · Dec 27, 2011, 01:59 PM

In my code area the toilet is not vented and it is possible that the kitchen sink waste might pull the trap seal on the toilet, that being said it does not mean it will not work or the trap seal will get pulled. I think Mark would be better qualified to answer your question since I think he is in your code area.

massplumber2008 · Dec 27, 2011, 03:06 PM

Hi DennM

Hey, I see you have been working real hard and me and Puffmugs have been trying to help you, but somehow we just aren't clear on the issues.

If you want, I will draw up a diagram showing you the code violations... not too many by the way, but you have 3-4 issues that need fixing. Let me know if you want me too, OK?

Also, reread post #7... see if you can catch a couple of the issues... let me know more, OK?

Mark

Dennm69 · Dec 27, 2011, 03:41 PM

That would be great

Dennm69 · Dec 27, 2011, 08:42 PM

Thank You, so I should change the san tee, I one of your previous correspondent you said it can stay. "means the 3" sanitary tee at the base of the stack can stay now! This 3" reduced to 2" will now act as the toilet vent...

Milo Dolezal · Dec 27, 2011, 08:54 PM

Looking at your photos, I would like to add my 2 cents based on UPC Plumbing Code.
I am sorry to say, but under UPC the following would NOT pass your rough-in plumbing inspection:

1. Toilet is not vented
2. Shower is not vented
3. 3" Comby fitting cannot be used in horizontal position ( use Y or Y+45 to make the turn )
4. 3" San-T cannot be used as transition from vertical to horizontal ( use comby or Y+45 to make the turn )
5. 3" clean out with 3" San T: 3/4" snake with knife will not make the bend in 3" Sant T ( use comby fitting or Y+45 to make the turn )
6. 3" main pipe has to end either with toilet or clean out. You cannot taper it off to 2" and continue with it to another fixture.
7. Dirt-Arm (2" horizontal washing machine drain) should be no more than 5' long
8. You cannot reduce your vent from 2" to 1 1/2"

Back to you. Milo

Actually I was trying to help you keep some of your work without having to rip it out, but Milo and Puffmugs are really right in that the toilet and the shower drain (thought that might be a floor drain? ) need to be vented differently here!

As much as I wanted to reduce your work load this got messy after you missed (or misunderstood) my very first post on this stuff where I said, "You CANNOT use sanitary tee fittings on the horizontal as you have for the toilet and the base of the stack. Here, you must have a wye fitting for the toilet (and a new 2" vent), and a long sweep elbow or combination wye/45 at the base of the stack.

In the first thread I said, "Here, code wants you to install a WYE fitting after the long sweep elbow at the base of the stack."..again, thinking that alot got lost between threads and just all the darn typing!

Here is what all these guys and I really wanted you to do to start with... see image. Again, long sweep elbow out of the ground to the cleanout (ends run)... branch off wye behind the long sweep elbow for the rest of the stuff. Vents off each branch (seen in green) are supposed to be run above the centerline of the drain so this was almost doomed from the start ya know?. see what you think about all this. I'm sure we can get this up and running pretty good overall!~

Finally, as Milo also pointed out, you have reduced the 2" vent to 1.5"... can't do that! Also, don't forget to add cleanouts at the kitchen drain, the 3" and the washing machine drain!

Sorry for all the back and forth here...
