    Mechanical Room wall rating - 2018 IMC

    I think you'd find such requirements in the IBC, not the IMC. For example the requirements of the shaft are in 713. I don't think there's a simple answer to your question, because it begs questions involving rated corridors and the like. I don't think there is a requirement on the mechanical...

    Urban Code Enforcement Other Related Topics group

    I'm wondering if others see value in a Related Topics group specifically oriented towards urban code enforcement, including code development. In a dense urban environment, there are particular features, like lot-line-to-lot-line development, that change considerations sometimes. I'm not on here...

    C900 PVC as Water Service Pipe

    Not for a house: that's why I said "larger water services": i.e. a commercial building, or a multifamily building. They can be quite a bit bigger than that. For an IRC house, typical sizes are more like 1".

    C900 PVC as Water Service Pipe

    I think you might be right, but that's fine for larger water services: it's often 4" or bigger. It may be that it's not that fun to transfer to/from C900, that is, joining it with the rest of the pipes in the building.

    C900 PVC as Water Service Pipe

    Well, I'm pretty sure the C900 industry would like it to be used for that, but they are not ever going to meet the standards that are in the International construction codes for water service pipe right now, because it appears to be mentioned right in the quoted standards that it has to be...

    C900 PVC as Water Service Pipe

    I am curious if anyone has done a deep-dive into C900 as Water Service Pipe? If I look at the 2012, 15, and 18 IPC, as per table 605.3, the only allowable PVC must meet the following standards: Polyvinyl chloride (PVC) plastic pipe ASTM D 1785; ASTM D 2241; ASTM D 2672; CSA B137.3 Now, C900 by...

    Sump pumps in Elevator Pits

    THANK YOU! Super helpful! And thanks so much for the specific A17 reference. I'll bone up on Firefighters emergency operation. Since this is an old, existing elevator (traction), I suspect it doesn't apply. K

    Yeah, I read that thread before I posted. It was what gave me hope there might be some elevator guys here...

    Sump pumps in Elevator Pits

    Hi, I am pretty green with respect to Elevator code. I'd appreciate some more experienced perspectives. The issue has to do with a sump pump in an existing pit. The elevators are being replaced. The pit was built without a sump pit. Is there anything requiring a sump pit? Can a surface-mounted...
