MPdesign 0 Posted December 20, 2016 Report Share Posted December 20, 2016 2008 building with a lot of buildup inside CPVC pipe. Mostly near the boiler for the circulating hot water system. Is this lime? Have you guys come across this and what did you do? Merry Christmas! Click to Enlarge 25.89 KB Click to Enlarge 36.28 KB Quote Link to post Share on other sites
mjr6550 5 Posted December 21, 2016 Report Share Posted December 21, 2016 Is it hard? In the photos it looks like it could be fiberglass. No saying it is. Quote Link to post Share on other sites

Chad Fabry 55 Posted December 21, 2016 Report Share Posted December 21, 2016 It looks like an overzealous application of boiler sealer. Were there any obvious past leaks? Vortices are created at the joints and elbows where dissolved air is liberated which then reacts with the sealant. Quote Link to post Share on other sites
