I mentioned this job a couple weeks ago and I post these pictures to serve as a classic example of what you get when:
A. the person doing the job has no clue (he was btw a licensed contractor believe it or not)
B. no plan is in place before beginning to solder pipes
Note the yellow tubing. It is pex after a fashion in that it is polyethylene tubing. The problem is that it was made for underground gas service and had no O2 barrier. (just a neighborly heads up to all you proponents of non barrier tube) The Trianco Heatmaker boiler lasted about 3 years before corrosion and sludge caused by the absence of a barrier took their toll.
Drew and I removed everything you see here, abandoned all the loops of non barrier tube and started from scratch with the installation of her Garn. Pics of that to follow.
