About US    

Di Napoli Plumbing Parts was founded in the basement of Leonard Di Napoli's home in 1954.  Leonard  had been in the plumbing industry for 50 years as a plumber and a plumbing salesman. He believed that people would need a supplier of  replacement plumbing and faucet parts. He was right.  People do need parts.  While working as a salesman he began collecting parts and storing them in his basement.  Word spread of his small inventory and soon  he had plumbers and his neighbors knocking on his door at all hours looking for parts!   He rented a small store to inventory his parts. In 1959  Di Napoli Plumbing Parts became incorporated, and officially began selling just plumbing parts. Leonard set up a mail order department, where he shipped parts to local supply houses. He bought a lathe so he could make stems if he didn't have them. He would never let someone leave until he solved their problem.  He believed strongly in quality and customer service. 

We are now in our 48th year.  Our goal today is the same as it was in 1959. "Provide to our customers quality parts with the best quality service". We now stock parts for over 300 manufacturers.  Plumbing Parts are our business, not a sideline!!  Whether it's a lavatory, shower, or kitchen faucet parts, we're your parts specialists.
