elgato Posted February 18, 2009 Report Share Posted February 18, 2009 Is this PEX ? It has clamps like polybutylene, but is colored similar to pex. The markings on the tubing were, 8137.5 NES PP 101 UPC. This was in a manufactured home built in 2000. Click to Enlarge 39.9 KB Quote Link to comment Share on other sites More sharing options...
msteger Posted February 18, 2009 Report Share Posted February 18, 2009 Sure looks like it. Was there an ASTM number printed on it? Are you sure it didn't say "B137.5" instead of 8137.5? Quote Link to comment Share on other sites More sharing options...
elgato Posted February 18, 2009 Author Report Share Posted February 18, 2009 Well, it may have been a B in stead of an 8. Would that be significant? Quote Link to comment Share on other sites More sharing options...
hausdok Posted February 18, 2009 Report Share Posted February 18, 2009 Hi, It looks like a manufactured home where the hot water polybutylene lines were replaced. If memory serves, it was the hot water side where all the problems were with the PB fittings, No? ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
msteger Posted February 24, 2009 Report Share Posted February 24, 2009 Yep, hot chlorinated water seemed to be the biggest of PB's problems. And yes, if its a "B", then its a code number for PEX. Quote Link to comment Share on other sites More sharing options...
