Need help identifying this cast iron fitting

[grumpydad]

Hello guys,

First of all thank you for all the combined expertise here in plumbing. I have learned a lot from here while hanging around without registering.

I have this cast iron fitting sticking out of the floor in my basement that I have exhausted my Google-fu trying to identify what it is and how it connects to the 1-1/2" PVC pipe above.

The PVC pipe serves as a drain for the kitchen sink upstairs and also a laundry sink and a standpipe downstairs. There appears to be no separate vents for the laundry sink or standpipe. Not sure if this is ok.

I am in Minnesota so MN plumbing code before 2015, UPC now.

The fitting is a tapped HUB 45 deg and the PVC appears to have been installed using GOD KNOWS WHAT


Possibly a rag / oakum and lots of caulking

Thanks! At least I know what the fitting is called now!

Do you also think if there is a bushing between the PVC and the tapped hub? What would be the size of the hub then?

 

[Sylvan]

Years ago when we had to caulk a galvanized pipe into a hub we would cut a galvanized coupling in half so it would not pass through the hub and allow for a proper caulk joint

In your case I have no idea what they did other then saying is is sloppy and improperly installed

What would be the size of the hub then?

What is the OD of the hub? I suspect that is a 2 inch, but check dimensions.

Why are you asking? Got an action in mind?

I would get two stainless steel digital calipers: a long-reach one https://www.harborfreight.com/6-in-long-reach-digital-caliper-63714.html, and one that has inside and outside measuring. https://www.harborfreight.com/6-in-digital-caliper-63711.html

I am putting in a laundry room and bathroom in the general area this pipe is in and wonder if it is worth the effort to upsize the PVC to 2" or just install a saniflo system and call it a day.

There is already 1.5" piping for a laundry sink and a standpipe but they are not vented at all. They are using the kitchen sink drain, which is the PVC pipe, as vent.

Plus, they don't work with the layout I have in mind

If you're installing a bathroom and you have the option of connecting to a gravity drain, that is hands down the better option. It requires a minimum 3" drain. I would carefully read the requirements for a Saniflo connection as well. I thought that they wanted to be connected to 3" as well due to the pump volume.

Cut the floor and install 3" pipe for a toilet.

Saniflo is only if they're is no realistic way. Thats my opinion. Id rather do the work and not fix gunked up junk later.

When I say gunked up I mean gunked up with poop.

I am not a plumber or a pro.

If you are going to rip up that floor, you should get the tile tested for Asbestos.
