How to Protect PVC Pipe

Taking steps to protect your PVC pipe can prevent damage later.

The invention of PVC pipe has been a godsend for both professional and do-it-yourself plumbers. It has a reputation for being easy to cut, join and equip with fittings. Even though it's a plastic, PVC--polyvinyl chloride--has proved its durability. By taking some steps to protect it, you can prolong the trouble-free life of this pipe even more.

Instructions

1. Bury PVC pipe beneath the frost line in your area to protect it from freezing and bursting when cold temperatures arrive. Look up your local building codes for the required depth to which you must bury PVC pipe.

2. Back fill the excavated area properly for buried PVC pipe, making sure to add soil beneath the repaired pipe section before piling dirt on top. This will prevent stress on the pipe. Compact the soil well over the top of the pipe.

3. Slip foam insulating sleeves over long runs of exposed PVC pipe to prevent freezing. These foam sleeves are split for easy installation, and you can add some duct tape to secure them. Do not compress the foam, however, as this will reduce its effectiveness.

4. Paint PVC pipe that will be exposed to the sun with a light color of water-based paint. This will protect it from the ultraviolet rays that can eventually break down the material.
