Ray May Plumbing has been serving Los Angeles County and the Inland Empire since 1961.

Based in Upland, CA, Ray May Plumbing is a family-owned and operated plumbing company that has served the local community since 1961. 

By offering unsurpassed professionalism, Ray May has built a solid reputation throughout the Inland Empire and into Los Angeles and Orange Counties. Customer testimonials about our work will show you for yourself.

We are blessed to have a territory that extends from as far north as Mt. Baldy to the southernmost part of Chino Hills and from the Covina / Glendora area in the west to Fontana in the east and all points in between. 

It’s funny how, with such a broad territory, we can actually be in different climates and weather at any given time. 

On the same day, we will fix a frozen and burst water line in Padua Hills and install a new water supply line for an icemaker in Ontario.
