    Re: Venting for a basement utility sink

    So where exactly did the vent tie in?

        Boy I really need to open up a new code book.

        I thought ejector vents had to terminate separately from the rest of the plumbing system. Has THAT changed too?

            It use to be that ejector crock vents had to run through the roof seperately because they were considered seperate systems..Then they starting allowing us to tie back into the house vents..Now it's IPC and I guess anything goes..

              So you're allowed to go horizontal with the vent below the flood level rim of the drains above it?

                  You use to be allowed as long as there was an accessible cleanout within 24" of where you broke the vent flat or something like that

                    Strange, I don't think that installation would pass inspection where I come from.

                      In Mn, which uses the Minnesota Plumbing Code, the vent would have to be 6" above the flood level rim of the highest fixture in that branch interval. (Assuming the laundry tub is the tallest fixture in the basement, the vent would have to be 6" above that before it could be run flat.

                      No mechanical vents are allowed. Period. Vents must terminate in open air.

                      Perhaps the code is different where you are.

                        I just thought the 3 1/4 bends right out the top of the basin was pretty convoluted, and definitely not high enough to go horizontal yet...

                          Did you look for a future vent?

                            The tank vent vents the tank not the fixture. The elbows are fine.

                              Here in Mn if the sewage ejector pump is pneumatically operated the vent must run separately through the roof, if the ejector is electrically powered the vent may be joined to the rest of the waste and vent system. Mn has it's own State plumbing code but it's similar to the rest of them.

                              I've never seen a pneumatically operated sewage ejector.

                                When was the last time you ran across a pneumatic ejector?
