Hello, I have two questions about our basement bathroom sink plumbing. I’ve attached three pictures to show the plumbing. The first picture shows that the sink drains vertically into a cast iron pipe in the floor. [This is how the builder’s plumber did the rough in.] The second picture...

Hello, Is it OK code wise, and functioning wise, to vent a drainpipe off of another drainpipe that is well vented? I have a 3″ toilet pipe vented with a 3-inch through the roof pipe and another 3-inch toilet drainpipe, nearby as they both get closer to the main stack (within about 8 inches)...

This is a response to my initial question about moving the shower drain: dj2 said: ↑ 1. You can move this drain to meet the new tub drain location, but you will need to break up and remove more concrete. 2. Once you remove the gravel and rocks around the drain hat you have, you will see the...

Thank you. I've attached 3 more pictures and my ultimate question is: What is the correct way to connect the 2 inch cast iron pipe together? Please see pictures and info below. So, I'm going to break up more concrete and cut off a section of the old CI drain with p-trap included. This is an...

Hi, We have a 2 inch cast iron drain pipe rough-in in our concrete basement floor. Picture included. It was installed by the builder's plumber when the house was built. This drain was used for many years with a shower installed over it. No issues. We're upgrading to a tub/shower combo. (1)...

Thank you.

Hello, I want to disconnect 2 inch PVC from cast iron so I can install a new bathroom vanity in the basement. The photo below shows the 2 inch sink drain PVC installed in a cast iron pipe which then goes under the concrete floor. How do I get this apart? Thanks.

Thanks!

Thank you.

Hello, I have three questions and a picture for each of them. (1) Is it safe and effective to "seal" off septic tank gases by using a Fernco rubber cap? Or, should you glue on a cap? (2) Is the way I did the plumbing coming directly out of the toilet flange OK or will it cause you to often...

Thank you. And, that first fitting is exactly what I'm talking about. FYI, I have limited height because the floor joists are 2x8. I don't know if it matters that I need to use an offset flange because a floor joist is in the way? I would think not. If I used the 4x3 closet elbow, could you...

Hi, Brand new member here. Looking forward to “meeting” you all and learning a lot more about plumbing. I did search on this first. Anyway, my question is: can a 3 in. “PVC DWV 90 Degree Spigot x Hub Street Elbow” be directly connected to the toilet flange?
