Plumbing through fire wall
 

Anyone know where I might be able to find a fire barrier collar to cover 1-1/2" plastic pipe that penetrates through a fire wall? Building code states it's needed. Need something locally in Calgary.

Don't know off hand, but check your local EMCO, they should be able to help out.

I've put plumbing through firewalls before and just transitioned to a copper pipe for the pass through.
Is this a drain or vent?

Drain, 1-1/2 ABS pipe.

I would just do a transition to copper and fireproof caulking (the red stuff, I think).

I would have to check to see if that meets code. I am pretty sure that you would need a donut. If I wasn't in the middle of an office move I would look for you.

Do you know what the rating of the wall is (45min, 1hr or more?) it may change what can be used.

I built a dental office where we had to pass abs drain, vent, suction and vacuflo lines through fire rated walls. It all passed.:smile:

Not sure what the rating is, the drywall is just standard fire rated 1/2". Building inspector just said I need a fire ring around the drain. He hummed and hawed about it so I don't think it's a huge deal but I can't just use the fire rated sealant, has to be the metal ring/donut.

Got what I needed from Hilti, thanks all!.

I have to laugh at these building inspectors though. Basically I have to install fire rated drywall on the inside of a basement exterior wall because that side of the house is 2-5 cm too close to the property line, despite the fact that the distance between houses on that side of the house is actually 2-3 feet greater than the other side. Next the drywall has to be installed all the way from the basement floor to the sub-floor on the main level meaning I have to notch the drywall to fit between the joists. OK but the joists are web shaped so filling them completely will be difficult but the inspector says it doesn't have to fill the web and just has to butt up against the top and bottom courts. However the drain from the shower will have to protrude through the drywall section between two of the joists so I have to use this special fire ring and sealant to complete enclose the gap to special fire requirements yet there is a 1.5" open gap on each side where the drywall means the joists. Correct me if I'm wrong but this makes no sense and I'm pretty sure the inspector knows very little about what he's doing.

The inspector is technically wrong, the drywall has to follow the cut of the web of the joists, there is a way around that, but it would go well beyond the discussion here. I spent way too much time figuring these details out for the inspectors.

As for the fire rated exterior wall, it has to do with the property line, not where the other house is, as silly as it sounds, it is a good requirement.
