Understanding Plumbers Putty and PVC Pipes

The Compatibility Factor plumbers putty on PVC

Plumbers putty has traditionally been used on porcelain, ceramic, and metal surfaces. Because of its pliability and sealing abilities, it is an ideal choice for sinks, drains, and faucets. When it comes to PVC pipes, however, compatibility is an issue.

Because PVC is non-porous, it does not absorb water or allow things to penetrate its surface. While a plumber’s putty creates a watertight seal, it may not stick well to the smooth, non-absorbent surface of PVC pipes. Because of the absence of a connection between the two materials, the putty’s effectiveness may deteriorate with time.

Another factor to consider when using plumber’s putty on PVC is the potential for discoloration. Because plumber’s putty is oil-based, it can leave ugly stains on PVC surfaces. These stains can be difficult to remove and can have a detrimental influence on the appearance of your plumbing fittings.
