Wouldn't the toilet vent be the line that is going into the attic right by the toilet?

Currently only one lav exists. We were adding a second lav (no grandfather )because there is a lot of room there (101") and is all vanity today (well a few weeks ago when I ripped it out ). Distance from the first lav to the vent behind the toilet is about 2-3 feet.

I agree on the wye, not sanitary T.

Your post 41 drawing shows toilet draining to the left, then flat back to 3 inch vent with lavs as the wet for a wet vent. As you know your single lav was on it as a wet vent because that's how he plumbed it. Adding an additional lav will make you up size your pipe to the lav that is closer to the 3 inch vent.

It's all a wet vent on that toilet. All piping must be sized per the wet vent section.

It might just be easier to pipe your drain on the tub to where you have now drawn. post 41

Then wet vent the tub with your new lav. 2 inch to the tub 1.5 inch to the lav then vent. as you did in post 26.

No extra vent needed on tub.

That way your only messing with on part nothing elese.

This is what I think you are describing.



Was just in the basement. Depending on which side of the closet I come down it might make more sense for the line to come into the basement and instead of hooking with the 3" line that I show in this image it could be easier to run into the 3" coming from the kitchen and laundry. I don't think that would be an issue but I mention it for transparency.

Doesn't matter which 3 inch line you use. I think that is the easiest way to do what you want. Been a pleasure working with you.

Please get some support on all your plumbing and make sure it has proper pitch.

And I'm back...

I've started to execute the plan but I've had to make a few changes.



The first change was because of clearance issues I couldn't run the lower bathroom vent along the same path as before. It was too tight so I jogged it over a inch and continued up through into the attic where it will join the 2" vent from the new sink and tub and connect into the main 3" vent. I assume this is OK because I'm connecting two dry vents together well above the flood plains of any fixture.

The second change is when I went to run the new drain line down the closet wall I found that both walls were directly above joists. One of them was a doubled up joist as well. Since the closet is already kind of narrow I figured dropping the ceiling about 3" would allow me to drop the pipe below the the 2nd floor ceiling joists and then travel down the back of the closet allowing me to shift where I enter the basement such that I'm no longer on a joist. Is this a problem?

Thanks.

I'm not sure. I haven't had the water tested as I'm on city water. I'm sure it's on the harder side of things. The house was on a well at some point so I'm not sure if this is a product from a long time ago. When I've opened other pipes I have not seen buildup like this so I think the primary cause was the slope.

I was in housing as a apprentice so I was doing full rough in with layout by the second year. I also had a mean boss my brother that taught like a good union plumber.

LOL Will I ain't growing younger. But some good memories never hurt.

I did learn the business end of a shovel and how to use it correctly.

Pull pipe to fly up the building, load pallet baskets with no hub, clean up left over material on one floor and pack it up to the next, bust out concrete because some j-man missed a sleeve...... glad im beyond that
