PSI started as Richardson Representative Corp. in 1978 by Bobby Richardson. The company grew its roots in plumbing wholesale and customer service in Orange County. Bobby's son Scott joined the PSI team and has seen the company through various stages of development, from wholesale to pump system design.

With over 30 years of experience in the world of pumps, Scott made PSI what it is today. We are proud to be family owned and operated and shine that tradition over to our clientele. Offering prompt customer service and custom lift station designs, PSI has made its mark in the pump market throughout the whole United States. ​
