Flexible vent pipes?

Rob H

I'm in the process of installing 'can'/recessed lights in my kitchen. I cut a hole for one of the csans and found a vent pipe directly above the hole.

Can I cut the vent pipe and add a flexible pipe/hose to get around the can?

If it is a sewer vent you will need to reroute it with pvc. No flex pipe.

It appears to be a kitchen sink drain vent - it this considered a 'sewer' vent?

TazinCR

Yes and you should be able to reroute it with pvc.

It would have to be re-routed with PVC. There are no flexible options unfortunately.

Although there is 1-1/2", 2" and even 3" flexible PVC out there, it isnt approved for drain, waste and venting. Some 45s, a little bit of pipe and time though and you'll be home free.

Before you tear down the ceiling to re route, if you're lucky you may be able to offset up diagonally or sideways a few inches by using a couple of 45 degree elbows with a 2-6" stub between them. Don't try to swivel or push your pipe sideways since you may crack a hidden joint down line and cause more work for yourself. Also remember to keep your pvc away from the future heat of your light pots.

There is no clearance requirement between DWV pipe and can lights, but it would be a good idea to maintain a little space for good measure.

Also, when you re-plumb, don't accidentally create a point to prevent water from passing or a point of accumulation. Any new plumbing should be level with the pipe's flow.
