    Re: Sand interceptor

    In this neck of the cold woods the sand interceptor is a small trench 6" deep12-24" long that precedes a flammable waste interceptor to keep from it having to be pumped as often.So small trench with cover to catch sand needs no vent.Flam waste tank needs a vent.

      It is a trap. It needs a vent.

        In this neck of the cold woods the sand interceptor is "some stupid square hole in the floor with a metal cover that we decided to build this kick a$$ work bench over"

            Around here, they are in every parking garage. Basically a big pit, usually 4' in diameter, 4-8' deep, sometimes smaller, often bigger, that all the floor drains drop into a couple feet below the lid. An outlet line, with a tee if you are lucky, or a 90 down if you are not, ala a septic tank, takes water out on a level a few inches below the bottom of the inlet pipe. Sandy drip water from off of cars makes its way into the pit, the sand falls to the bottom, floaties stay on top, the outlet takes relatively clear water up thru the t or 90 from a foot or so below the surface and out, sometimes to san sewer, sometimes to storm sewer, sometimes to a drywell.
            This is my reminder to myself that no good will ever come from discussing politics or religion with anyone, ever.

              Actually it is not a trap. It is an interceptor. A trap needs to be vented in order not to lose its prime and prevent sewer gas from escaping. An interceptor has a totally different purpose.

                Take a look at the #8817 a very large sand interceptor (push the button near the top of the sheet). It has built in vent tappings.

                The 8811 does not have them built in, but notice they all have a trap seal.

                Look at the solid intercepters. All are actually drum traps and all need venting to work properly.

                The answer to the original question really depends on what the installation is for and the design of the interceptor.

                Keep in mind that a grease intercepter has always required an air inlet, in addition to the normal venting.
                If I was doing the job I would ask the inspector what he wants and plan on doing it that way, before quoting a price!

                What we decide here doesn't make any difference if the inspector won't approve it.
