Hi All, long time reader of these forums (thanks for all of the knowledge shared!) first time poster.
**Update** I contacted the city's chief plubming inspector and he confirmed that code does not require burial and that suspension of the lines was allowed**.
A 12-unit 2-storey building that I own a unit in is having sewer gas issues and there is standing water (and other stuff!) in large sections of the buried horizontal runs of sewer pipe. We are looking at replacing part or all of the cast iron. Trenching to dig out the existing pipes and replace with PVC would be very unpleasant / labour intensive work. My code question is, does code require the horizontal runs of sewer pipe to be buried, or can they be hung from the floor joists and sloped toward the connection to the city line?
If hanging of the PVC sewer lines is permitted, and we can forego massive amounts of digging, I'm hoping that we could replace all of the cast iron for not too much more proportionately that a small run alone. The building manager is saying that he spoke with a licensed plumber who says that code requires the lines to be buried (though the plumber can not provide any reference to the section requiring this.......). Can anyone please confirm what is required by code (burial?) and reference the relevant sections?
Thanks!
