Plumbing through fire wall

[sphelps]

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.
