- Locate a flexible rubber coupling. They can be found at hardware stores or online. Many types are available for your specific needs. There are even types made that have eccentric diameters to fit with different size pipes, as well as some that are corrugated and made specifically for PVC applications.
- Attach a correct sized flexible coupling to the PVC side first. Push the pipe approximately halfway inside, then use a screwdriver to tighten the hose clamp attached to the coupling, which will provide a leak-proof seal.
- Push the flexible pipe into the other side of the flexible coupling until it meets the PVC pipe in the middle. Tighten down the clamp firmly onto the flexible side for a leak-proof seal.
How to Connect 1 1/2 PVC to Flexible Pipe
Rigid PVC pipe and any flexible type of pipe are made of dissimilar plastics, and therefore cannot be glued together. The most common form of flexible pipe is made of a plastic called Pex. Connections for Pex are made of brass or bronze, which are again totally unsuitable for joining together with PVC pipe. Unless you want to change the entire plumbing system to copper or PVC, there is only one way to connect a 1 1/2 inch PVC pipe to flexible pipe.
