Gotta love ECN! I post a pic, trying to (pick the example) either show off a nice bend, or underscore the need to go beyond simply selecting a method, and actually consider actual conditions.... and we're back to examining the instal of a plastic LB.

I believe that I had explainde that the distance away from the wall was made necessary by the 90 degree bend on the opposite side of the wall. Cut the pipe sooner, and the LB would be at a funky angle; bend it tighter, and you've violated required bend radius. Put an LB on the inside, and it will be enclosed in the wall, and inaccessible.
In any event, there is less than two inches of air under that LB. Not visible in the pic are either the curb, or the roof overhang, that discourage passing THAT close to the building.
Not a work of art? Never said it was. I make no claims as to my work being perfect. Indeed, that my work is so much better than some is a thought that terrifies me some days....

I had a blank check on thet job, as far as design was concerned. PVC was chosen for reasons that had absolutely nothing to do with either price, or ease of install. While I did everything I could to run the pipe in a manner in which it would not be subject to damage, or tripping over, etc... still, it was exposed- so I chose sched 80.

Now, for those not familiar with sewage at all, it may surprise you to know that the stuff itself can be tough on materials. Not to mention that some of the chemicals used are themselves pretty nasty. This is one application for which PVC is a good first choice- even specialty metals often fall short in these applications.

Now, getting back on topic...

I submit that damage is evidence that the original wiring method failed to meet the code requirements for protecting the wires. I don't care that the stuff was crunchedby a tank; what matters when you find this is that you take steps to prevent this damage from happening again. It's not enough to just replace with more of the same.

Looking at the two pics I submitted... it's not a matter of "might be," it's a case of "was." In both cases, the use of ANY exposed wiring method might be questioned, as the stuff got hit. Since the walls themselves look to be in pretty good condition, perhaps, in this case, Romex fished to cut-in boxes would be a "superior" method to running pipe.

Of course, we only know this with hindsight. Isn't that a large part of a 'service' call- looking at what didn't work, and fixing it?
