Customer Reviews


At Pipe Guard USA, we care about plumbers more than anyone in the world. Our motto “Created by Plumbers, for Plumbers” says it all. Pipe Guard USA started as a father and son duo (Stepan and Peter Zamkochyan) in 2014. Upon completion of a sewer liner. They wanted to do more to protect themselves from anyone sticking a snake in their CIPP liner, instead of writing a note on a paper invoice stating “MUST USE HIGH PRESSURE WATER TO CLEAN SEWER LINER”. The duo went to their workshop to come up with a better way to mark their sewer liners and created the perfect solution for the industry. Today, we are proud to say that Pipe Guard USA is certified by IAPMO (IAPMO IGC 341), is made in Los Angeles, California with all American ingredients (HDPE). Pipe Guard is the most effective way to mark your sewer liners, backflow values or grease traps. We appreciate you taking the time to get to know us, please email us at with any questions or suggestions.
