Frequently Asked Questions

Q. "What is a PVC expansion coupling?"
A. A PVC expansion coupling is a repair coupling for PVC pipe. If there is a leak in the pipe, the section of pipe with the leak can be cut out of the line. The expansion coupling is glued onto one exposed end of the pipe, and then expanded by pulling on the telescoping end; then, it's attached to the other exposed end of the PVC pipe with a standard PVC coupling.

Q. "How do I glue PVC fittings and valves to the pipe?"
A. Most PVC manufacturers recommend that the installer follow the instructions for the cement and primer that is being used. Their instructions are usually found on the label of the container.

Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.
