My biggest confusion is the 3" vent/stack. it comes vertical from roof, connected nothing on the way, then down to basement and made a 90 turn to horizontal. Does this vent count? Where it started not be regarded as a vent? From the replies, I learn that the sink connected to this horizontal...

I took out the old cast iron pipes this weekend, and put together another dry fit. I have both first floor bathroom and the on-going basement bathroom. The basement shower-tub need a vent, but I don't know I should vent through a new revent to roof or anywhere in the existing waste-vent in...

I took down all the cast iron pipes today, besides, climbed into attic to have a Tee inserted into the vent pipe for any revents when needed. Tomorrow, Sunday, I am going to fit the pipes in then post a new thread with my venting questions. Thanks for many helps from this forum!

I am going to have the toilet line vented by connecting it to the old vent to roof. I couldn't show this in photo because it was blocked by the old cast iron pipe. I was told to need a re-vent for the sink too, so I am going to bore holes and make a re-vent connected in attic. I will cut the...

It seems my previous questions were "cleaned-out", but it escalated to vent questions. I should oringinate a new post on my questions on vents soon, so people having respiration difficulties can learn from my problems.

It's much clearer now. I am going to make the changes and show you the photo asap. Thank you so much!

It will be good if I can raise the toilet line, a local plumber told me to connect toilet line to the stack first(is it because waste from sink is good to flush toilet waste , or if save heavy pipes the same time, or both?), so I followed his instruction. Now it seems not so critical. There is...

David: I loweredd the toilet waste by 45 degree to the horizontal Wye. How does it looks this time? I used the fittings on hands, but I can lower the toilet waste before it goes horizontal too when got the long turn elbow. I don't know how it is going to affect the restriction of standpipe...

BA, hj and Grumpy: Don't worry about the back pitch, it's a dry fit, so "something" is not there yet:), but I will make sure this will not really happen. I have a cleanout at the base of the stack, so I guess I will change the Y with a long radius elbow. How if a Wye instead of Tee on the...

Hi, Geniescience, there is no vent for the toilet branch; it is 4 feet from the flange to stack. Is it still good to replace the Tee with Wye? An existing cleanout is on the stack just above ground. The horizontal 90 vent bend connects to a 1 1/2 vent for a basement sink(the little white thing...

I am replacing cast ion pipes with schedule 40. To route the toilet branch from vertical to horizontal, I used a Y. Can I replace the Y with 45 elbow, or a 90 long sweep, saving the cleanout? http://picasaweb.google.com/abrahuang/HouseBasementPlumbing/photo#5116227117896496402 Another cleanout...

I am installing a new bathroom in basement. A new section of capped pipe was slid in through under foundation by a pro, connecting the sewer main to street. Unfortunately, after uncapped it, I found out a pond of water wanted to stay at a level about 1 inch above the pipe bottom. To connect...

Breaking the cement is not so easy. It took me whole Saturday to cut the cement with circular saw and then sledgehammer 10' . I am to tired to dig the trench today.

Thanks for the many helps from here, I put together the newest version: Pls click to enlarge. Does this look good? Do I need a cleanout at the 1 1/2" 90 elbow for accessing from back of the wetwall? Or change the 90 elbow to 45? I ordered the 27x54x16 tub, it was said to be for above floor...
