Ron, I think you have raised some good points here. I must admit that I may not have thoroughly thought through (whew, say that three time real fast) all the consequenses of my actions in this situation. However, I may have lucked out in this case because the tap water that comes into my shop in the PVC pipe that goes through the wall which is epoxied (yes, the subject epoxy application) in place in the wall sounds just fine to me. There seems to be no adverse effects from my cavaleir use of this material.
