I’m helping with parents' kitchen remodeling and will take down my vent hood cabinet and do away with it. I just want vent hood straight up to ceiling for a clean modern look. But when I look inside current cab, I see a pipe coming in and out of the wall about 10 inches in length and 1.5 inches circumference. It looks metallic like chrome. Can someone tell me what it is and is it possible to hire a plumber to hide it in the wall?

    Be aware that a range hood that far from the range won't be nearly as effective at collecting moisture and odor.

    BX galvanized steel armored electric cable. Typically used where conduit is required and the situation makes conduit difficult to use. Commented May 31, 2022 at 14:55
  • You would hire an electrician not a plumber. Seeing that there is an outlet in the cabinet an electrician may be able to utilize that for the vent hood wiring. Commented May 31, 2022 at 15:01
  • If there's already power there, it makes you wonder why someone would bring more down the wall like that… unless it's actually gas.

That's flexible conduit, which protects the wiring for the range hood. It was apparently added after initial construction of the home.

The first thing you do is switch off the breaker. Then disconnect the range hood and push the wire and conduit into the attic while you do your remodel, then pull it back into the range hood and reconnect. Keep the wire nuts on the wires in the meantime in case the breaker gets turned back on prematurely.

  • I have some of this exact conduit in my kitchen cabinets from the original build where outlets are mounted away from the wall. I think it may be a precaution against damage to the wires from shoving junk around in cabinets. Commented Jun 1, 2022 at 23:17
