MPdesign 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 Link to comment Share on other sites More sharing options...
mjr6550 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. Link to comment Share on other sites More sharing options...

Chad Fabry 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. Link to comment Share on other sites More sharing options...
