I have completed a rough from a 100 year old mud job that I completely ripped out, have replace all the old cast with new 4 inch pvc. Problem with inspector. I ran the 4 inch pvc up to the bathroom then put a 4x4 ty followed by a 4x2 ty too hook up shower and sink then a 90 elbow that would be for the flange on the toilet. Inspector tells me that's no good but won't teel me why or how to fix the problem. The old 4 inch cast ty also had a side sadle to accommodate the shower and sink but I couldn't locate one in pvc so I used the 2 ty's. Live in New Jersey

We had a few excellent plumbers here, it might be awhile though -- it would help if you could post a pic most likely though. -- Savage

thanks for the interest will try to explain in more detail as I am not a computor guy with pics and all that. Removed all old cast down to the cellar floor. 4 inch hub there I placed the donut and ran 4 inch pvc up to the bathroom then placed my 4 inch ty to run horizontal off that I placed a 4x2 inch ty to hook up shower and sink then the elbow for a toilet flange. Inspector claims that the 4x2 inch ty is not code but won't help any further. The cast I ripped out ran up to the bathroom were it hooked up to a ty that also had a side sadle so the ty had 3 openings 4 inch like any other ty and also included off to side a extra ty for the sink and shower

Do you know which code your community follows? Is it the IBC?

I'm sorry, but I'm not getting the "ty" reference.

Are you talking about a 'tee' or a 'wye'?

Tee

You used drainage tees instead of wyes or combos? Bet that made the inspector happy. Try removing the tees and use wyes or combination wye and eighth bends and see how that grabs the inspector. Good luck, Tom

Not having seen the work, but following along on your description of the lay out, it sounds like you have tee's on their back, which is probably why the inspector refused to sign off on the rough-in.

When used as a drainage fitting, a sanitary tee must be vertical -- Horizontal applications require a wye or combo.

Now I Understand. Yes The First 4 Inch Was Vertical And That Was Ok, Coming Off That Was A Horizontal 4 X 2. You Say That One Has To Be A Wye Or Combo. Can You Supply A Pic So I Do This Correctly As Inspector Claims He Will Only Come To Inspect Twice And After That I'll Have To Hire Someone And Spend $$ I Just Don't Have So It Must Be Correct Next Time He Shows Up.
A Wye Is That Like A Y In Appearance And I Never Heard Of A Combo?speedball1 Also Suggested A Eighth Bends But Don't Know That One Either And He Really Seems To Be Tops Around Here Can Anyone Supply A Pic For Me?

Okay, these are some common uses of a Wye, Combo and Wye branch from a groundwork about a year or so ago.

#1) is a 'Combo', which is a preassembled Wye branch and eighth bend. You can make your own combo by putting an eighth bend (a 45) into a wye.

#2) is a 'Reverse Combo', where the eighth bend is transitioned from vertical to horizontal.

#3) is an acceptable transition from horizontal to horizontal.

#4) is an example of the vent taking off vertically above the centerline of the waste line.

#5) is another example of an acceptable transition from horizontal to horizontal.

Believe if we ever meet diner and drinks are on me so rahway New Jersey is where I live look me up if ever in area. Speedball1 you live in Florida? My nephew lives in Daytona and owns and runs a bike shop. If you ever need something you got it! THANKS

I thank you Tom , both for your prayers and for your concern. You wish me a speedy recovery. I beat throat and tongue cancer, but as every cancer survivor knows there's a heavy price you pay when you beat it. I lost, my beard and whiskers on th left side of my face, my taste buds,( everything tastes like wet cardboard\) my salvia glands, The inside of my cheeks are like a bad sunburn,Nothing too hot or cold to eat or drink, 20 pounds and 4 inches off my waist line, I'm down to 124.6 pounds stripped, BUT, At 80 years oif age I'm begaininbg to bounce back. I can taste sweet and salty, I''m not losing weight so that's a plus. I post this in thanks for all the people who have supported me in my treatment and recovery. THANK YOU! Tom aka "The Speedster"

It should be noted that it was run in this circuitous way because it was well below the nearest manhole cover, which meant everything in the basement had to be routed through a back water valve before tying into the main waste line.
