Thread: Icy Stink Pipe

  1. #1

    Default Icy Stink Pipe

    I've noticed that there appears to be excessively moist air coming from my stink pipe, which freezes in the winter. i see ice clinging from the mouth of the pipe, as well as at a spliced (pvc) joint. it will melt in the sun, and drip off the roof into my garden, and generally cause the area to smell- i note a lot of gaseous odor as well in the colder months. I've recenty had my septic tank pumped, to no avail. Is icing like this normal?

    thanks for any suggestions!

    yeah, i haven't noticed any negative side effects other than massive icing- never seen the phenomenon anywhere else.
