Dead Legs - Legionnaire's Disease

Dead Legs - Legionnaire's Disease

New postby Gary_Smith on Mon Aug 02, 2021 3:53 pm

I've searched high and low and don't see anything "definitive" about dead legs. I know I read somewhere that abandoned or unused water supply pipe (if not being used) should be limited in length to twice the pipe diameter to help prevent Legionnaire's Disease. Does the plumbing code address dead legs?

I think it may have been in the 2003 IPC, then was dropped.

I found this: https://cdn-web.iccsafe.org/wp-content/ ... -IPSDC.pdf sscroll down to page 141/334 604.4 (new) ... I couldn't find that it had been voted on and accepted, and I don't find it in the code.

Love to know the background on why they dropped it. I think PEX (some of it, anyway) is sort-a prone to holding bad bio. You are awesome!
