Polybutylene residential fire sprinkler repair
Polybutylene residential fire sprinkler repair
(OP)
I have a contractor customer who cut through the side of a 1 1/4 inch polybutylene fire sprinkler pipe with a sawzall. We have used PEX adapters in the past but they only go up to one inch. This is an apartment building under renovation so the clock is running on this. They can't get a new CO until the sprinkler system is back in service.

Or call a fire sprinkler company that works on that type of piping.
Is the pipe orange in color??

I found this that says it was once approved for 13D systems but..... bottom left of page 311
But I remember venders trying to peddle this stuff for 13R systems but I never bought it.
That aside something like this would scare me to death from a liability issue.

Cross linked polybutylene has always been recognized in NFPA 13D. However, this person was asking about an apartment building. I may be getting slower and I don't always process information as fast as did when I was younger - BUT - I'm pretty damn sure it has never been allowed by NFPA 13R.

You touch that pipe for other than removal, you buy the system...

We never jumped on the butyl band wagon after a factory rep, demoing the product at our shop, screwed it up twice before doing a successful join. I told my boss that if he couldn't get it right on a table how are our guys going to do in some attic? Still I hate to tell the guy that he needs a whole new system due to one cut pipe. He mentioned shark bite couplings and I told him we couldn't stand behind them but he may have his plumber do it all the same.
