  1. Some instructions I have seen for roof vent terminations call for a flashing for PVC pipe. What would be the downside of using a lead plumbing stack flashing?

    Copper and aluminum SEC

    Is there any prohibition of mixing copper and aluminum for the SEC hots?
  3. Is anyone familiar with this type of foundation movement gauge? The foundation to the left of the crack was underpinned.

    Chicago inspection question

    Installing an ejector pit isn't going to protect the basement from sewage back-up/flooding in this situation unless the OP is going to seal the basement floor drains which I don't think is a good idea. Nearly all "newer" (post 1960) construction around here has overhead sewer so an ejector pit is a necessity whether there's a bathroom in the basement or not.

    Chicago inspection question

    If you're building has an all gravity sewer system, I only see disadvantages with installing a sewage ejector for the bathroom. Chicago § 18-29-712.1 Building drains below sewer Building drains that cannot be discharged to the sewer by gravity flow shall be discharged into a tightly covered and vented sump, from which stack the liquid shall be lifted and discharged into the building gravity drainage system by automatic pumping equipment or other approved method.

    3 inspection photos you should take to manage your risk

    I take about 200 pictures per inspection. At a recent 4800 ft.² home I took close to 500 pictures. I take at least one picture of every room and exterior wide shots of every angle of the house or building . The pictures are my notes which I go over one by one when I do the report. I use hand signals if the photo actually means something but is not obvious, and then of course, wide shots and close-ups of problems. It takes no time at all to shoot pictures from the hip while I'm walking or standing still. This is just how I am comfortable doing it. 99% of the pictures mean nothing. Occasionally, I will see something in a photo that I did not pick up live.
  7. The bathroom in an occupied house. Yes. I that is human excrement in the bottom of the bucket.
  8. I have a couple women in the house and was trained a long time ago to lift the seat and try to hit the middle. And, God forbid, don't ever forget to put the seat back down!!!

    Low voltage switches?

    What do you suppose all the switches might be for? This was part of a 2500 ft.² condo in a high-rise. All the wires come out of a gutter that I did not open.
  10. I know very little about mold remediation. Does this look like some kind of mold killer or just paint?

    Did you take a picture? 😄
  14. The insurance company of a recent client – MetLife, I think – is denying homeowners insurance because of galvanized steel pipe which they say can cause cancer. I have not heard of this before and I cannot find anything reliable on the Internet. I called my State Farm agent this morning and she said she has never heard anything about old galvanized steel pipe being a health hazard and State Farm would not deny coverage. Maybe it's a California thing?

    Cat IV Vent Clearance

    Thanks. I found this in my library for a Rheem direct vent. The vents are a little high. Lateral is not an issue.

    Cat IV Vent Clearance

    Does the 8 foot lateral clearance to sidewalls apply to PVC Cat IV vents? I did not see anything in the codebooks to suggest that it does not. However, I don't see anything in the manufacturer's instructions regarding this.
