Warranty Of 100 Years!
“My supplier gives me a 100-year warranty for the lining process we sell. I work inside buildings lining plumbing stacks and your representative is telling me your company doesn’t offer a 100-year warranty. Why should I use your Quik-Coating machine when the product I’m using now has a much better warranty to stand behind?”
A couple of things come to mind when I hear claims like this. First of all, a claim offering a 100-year warranty is something anyone can make. To perfect a warranty claim like this, you would need to provide a bonded warranty document backed by an independent party that’s been paid for by the supplier. Do you report each installation with documentation to your supplier? Do they provide you with this warranty with a bond for the job? If you have documentation, does it cover all costs to fix or replace the pipe or liner? If the answers to any of these questions are no, you don’t have a 100-year warranty.
All building projects including water and sewer lines are designed for 50-year service life. The tests for determining this are standards cited in ASTM F-1216 and ASTM F-1743 for CIPP products. Two of those tests utilize ASTM D-790 and ASTM D-638 to test plastics for this purpose. One of the tests to determine the life expectancy of a product is a 10,000-hour test.
Samples are placed under a load for 10,000 hours, then tested to failure to determine whether a product or process will last for 50 years. If the product still meets the minimum standards prescribed in the test then the product is expected to survive with certainty for the 50-year life span. To my knowledge, there is no material test to test for a 100-year life.
A final thought regarding applying CIPP to interior plumbing pipe is the consideration of opening a tie-in lateral to the stack. Many companies are applying the CIPP product by cutting gaps in the lining material where each tie-in is located. Others line over the tie-in and reinstate by cutting open the tie-in. Unless this gap or cut in reinstatement is sealed, there is a possibility of effluent sewage running between the host pipe and the liner at the tie-in if the pipe is leaking downstream from the tie-in. This has been evident in many projects causing IAPMO to ban coating cast iron pipe in the UPC.
While the liner may indeed survive for 100 years, if the leaks still appear in the walls and ceilings you haven’t solved the problem and your warranty may be worthless. We have many customers using our Quik-Coating process to seal these gaps and mechanical reinstatements as well as coat the entire pipe. The resin we employ expands slightly when applied in place and the expansion seals the pipe from leakage.
