So, you’ve done the right thing in your crawl space and insulated water supply pipes. All is good, right?
Not so fast.
During a recent visit to a home on Lopez Island, I came across this unfortunate issue: copper water pipes showing substantial corrosion—such as calcification deposits—despite the fact they were tucked into insulation.
However, insulation is useless and even harmful when it displays signs of moisture intrusion. In this case, that’s the precise scenario I encountered.
The prognosis wasn’t good because the majority of the water supply piping was concealed behind pipe insulation. Therefore, much to my dismay, I had to recommend that all the water supply piping underneath the home be further evaluated by a qualified plumbing contractor to make repairs as deemed necessary. The only way to do that is to remove the insulation and take a look.
