    Re: Sovent drainage systems

    WE have some of the fittings that we actually cut in half so my guys could see how they work. I will see if I can find them and take a couple of pics.

    The cross connect fittings have a baffle in them so nothing shoots straight across and a "diverter" in the vertical for the stack above to pass by without interfering with teh cross connnections.

    Kind of hard to explain until you have seen one.

    REgards,

      If installed per mfr. specifications, the system seems to work quite well. IMO

      I agree

        When I first popped into here, I was kinda dissapointed.
        Seemed more like a social chat type forum.
        I joined in hopes of seeing new breakthroughs, different approaches.
        This is good stuff, despite my initial disdain...I'm perked.

            I don't have a scanner but maybe these pics will help. Turn your head to the right for the first one to look right.

                  For what it's worth, ya really caught me with my pants down on this one, I thought it was some kinda scatter brained idea being pushed by a startup.

                    Ok,

                    I could not find the cut-away we made, but i did take a couple pics of a stack fitting.

                    In pic 1 you can see the baffles for cross-flow
                    in pic 2 its just a close up fo the baffles
                    pic 3 is a view from teh discharge end of the fitting.
                    pic 4 is just a isometric kind of view for craps and giggles

                    Pic 5, is a gloat, its a pic of a $700 dual bevel compound sliding mitre saw. Dewalt DW718 that I picked up new for $50.00 cash.

                    Yes, I did call the sheriff's dept and local P.D. to tell them I had it. I even gave the license plate number from the truck I bought it from. I know it was stolen.

                    I waited a couple months and never heard from them, so I called back. They said no one had reported one stolen, and just told me to enjoy it.

                    Later guys,

                      THE CDA has a book about Soil /venting (Sovent) from the early 1970's and the fittings were quite expensive in in those days


                      I am sure if you contact the CDA they will send you a booklet including the tables how to size and design them

                        I had no Idea that the sovent system had been in use that long. We just dont ever see it around here in "redneckville".

                            Re: Sovent drainage systems

                            Have worked in one building with the sovent system in Hawaii. Doesn't have any real problems with the system itself however after years of service some of the solder joints have failed. This may be due to the use of 50/50 solder. Fixing the branch lines is easy enough, but when the solder joint on the main stack fails it is a problem. Even with a water shutdown it is impossible to stop the water due to leaking toilet flappers.

                              Those who have installed two-stack systems may remember the separate vent stack with connections to the sewer stack, and battery fixtures using closet hanger combination fittings with built-in vents and so on - the vent stack had multiple connections from floor to floor to relieve the pressure buildup. The sovent system does the same thing, but all in one stack. I like the old way better.

                              Here's a two-stack system, and here's a better view of sovent specs in pdf format. The "two-stack" refers to the soil and vent stacks, while the gray water is separate.

                                Here's a blast from the past: first, a system from 1925 - 1950 Audel's Plumbers and Steamfitters guide:



                                And second, a three-tenement layout from the 1911 - 1923 Standard American Plumbing book. Note the refrigerator drains:
