Thread: Sovent single stack DWV system

I was looking at a building with the Sovent single stack DWV system. Does anyone have any experience or know issues with these systems? I've only seen this system once before about 10 years ago.

I inspected a mid-rise (7 stories) which was being constructed and had that system in it, about all I remember is that the installation and location of the components and the routing of the lines was critical - maybe 'critical' is the wrong word, more like 'important', and there was not as much room for installation error as with a regular two pipe system.

Not sure of any problems with it, only inspected it as it was being installed.

There were cracks and leakage problems, but all modern (cheap) cast iron has those problems due to storage, handling, and installation.

I've been doing this for a while and have only seen that system one before. The chief engineer said everything was good, but I've been lied to before. Thanks for the response.
