Hello,
Been following this site for years, but this is my first post. I do a lot of remodelling work on my house but about a year back we finished fully re'doing the 2 upstairs bathrooms. I hired a plumber to redo all the drains/vents and I pretty much did everything else. Anyway now its really becoming obvious that there may be a problem. Both toilets upstairs and the one on the 1st floor get clogged almost a few times each week. At first I thought it might be my 4 teenage kids using too much TP or who knows what. Both toilets upstairs are brand new also. However now I just drew up this diagram and tried looking at things with new eyes and I don't think this is vented properly at all. I'm calculating about 18 fixture units upstairs and 8 more downstairs. The main stack is 3" cast iron from the street and goes up about halfway to the 2nd floor. At that point it was cut and everything above is all PVC with 1 main exit vent through the roof. What concerns me the most is the long (> 10 ft) horizontal run between the two vertical main stack sections. I know everything is pitched properly but I don't know enough to say is this really a problem and could it be contributing to my toilet issues. Also if it is, how bad is it and what might be the best way to fix it. I also included a graphic with some measurements. Any thoughts/suggestions? Thanks in advance,
John....
