emalernee Posted June 23, 2014 Report Share Posted June 23, 2014 Click to Enlarge 32.84 KB Click to Enlarge 42.6 KB Cannot find a picture on the internet that looks like the fittings above. Looks like Brass fittings with a black steel compression ring. House was built in 1978. Recalls mention Zern with stainless steel rings and IPex with a zinc rich fitting. Can someone direct me to a website that I can add to the report. Link to comment Share on other sites More sharing options...
Chad Fabry Posted June 23, 2014 Report Share Posted June 23, 2014 The rings are copper. Are you sure they're leaking? It looks like condensation is the issue. A faulty crimp wouldn't affect the ring above the leak. All of the issues in your photos are on cold water lines. Link to comment Share on other sites More sharing options...
Mark P Posted June 23, 2014 Report Share Posted June 23, 2014 It they stored certain chemicals or fertizler in the same area it may have caused the corrision. Link to comment Share on other sites More sharing options...
Nolan Kienitz Posted June 23, 2014 Report Share Posted June 23, 2014 If it is condensation ... why not also be evident on the fitting at the lower right connection? I'm referring to the upper photo. Those locations not that far apart. CF - Good observation about condensation. EM - Any more similar deterioration noted at the cold water output of the PEX Manifold for the cold water lines? How about other cold water locations away from the manifold in other rooms/walls, etc.? Link to comment Share on other sites More sharing options...
emalernee Posted June 24, 2014 Author Report Share Posted June 24, 2014 Talked to owner today as I was picking up Radon CRM (22.3 pCi/L, maybe that is causing it, said with tongue-in-cheek). PEX is 10 years old. Took another closeup picture of a fitting behind the well pressure tank.. Owner runs dehumidifier, setting two feet away, all summer. Could someone not have put as much pressure on the rings as is required? Can the clamping tool get out of calibration?

Good thought but I'm thinking there will be much more condensation building up and running on a vertical line than horizontal, especially if there are multiple metal fittings on the vertical.

kurt Posted June 24, 2014 Report Share Posted June 24, 2014 It they stored certain chemicals or fertizler in the same area it may have caused the corrision. Drift..... I put a small bag of Scott's Turf Builder in my (large) boiler room. The 8" cast iron fittings on the steam risers all developed a thin patina of rust in about 3 days. No condensation, very dry...had to be the turf builder. Link to comment Share on other sites More sharing options...
Tom Raymond Posted June 24, 2014 Report Share Posted June 24, 2014 If the space has to be dehumidified for months at a time it's a pretty hostile environment. I'd say condensation too. I did a house that had the service mounted above the well chlorinator. There was a lot of black copper in that panel. Link to comment Share on other sites More sharing options...

Click to Enlarge 31.27 KB ..........yes, the tools are adjustable. There is a "go, no-go" template piece that is supposed to be used on every fitting crimp to check tolerance. How often do you suppose that's done?[:-paperba. I've adjusted my 3/4" crimper once in the past 20 years........Greg Link to comment Share on other sites More sharing options...

Also, each manufacturer will have their own tool and test method, not interchangeable. Link to comment Share on other sites More sharing options...

I'd say condensation too. In our area of Ohio if you don't run a dehumidifier during the summer you will have a damp basement. Thanks for all the comments. The plumber that installed the system is coming out to check it out. If I hear of a resolution, I will inform all. Link to comment Share on other sites More sharing options...

Also, each manufacturer will have their own tool and test method, not interchangeable. ........you're right about the tools not necessarily being interchangeable - but in practice (on the job site) materials are frequently a mixed bag - so unless you are talking about radically different styles of crimp, such as s/s cinch rings or expanding pex rings, one tool will be used on various mfg. rings. As far as how often to check tolerance, I've yet to see frequency spelled out by any manufacturer. Daily may be just right for a 50 crimp-day, not so much for a 500-crimp day[].....Greg Link to comment Share on other sites More sharing options...
jjeffzehnder Posted June 25, 2014 Report Share Posted June 25, 2014 I'm thinking if you are a setter the John will be OK but if you are not it could hurt! Seriously...how do these thing happen, which came first the service panel of the sink and the toilet? Link to comment Share on other sites More sharing options...
