What our plumbers say
Frequently asked questions
Do you deliver directly to jobsites?
Yes, we offer reliable delivery to jobsites within a 20-mile radius of our San Diego location to keep your project moving.
Can I set up a commercial trade account?
Absolutely. We work directly with contractors and offer trade accounts to streamline quoting, ordering, and billing for your business.
Are you open on weekends?
Our standard hours of operation are Monday through Friday, 6:00 a.m. to 5:00 p.m., catering specifically to the weekday needs of professional plumbing contractors. For after-hours emergency parts, call (619) 954-1259. Additional fees apply.
Do you only sell to contractors, or can homeowners buy from you too?
While we operate primarily as a wholesale distributor for local tradesmen, our doors are always open to homeowners who want to purchase professional-grade materials.
Why should I choose a regional specialist over a large chain?
The plumbing supply market includes massive national distributors as well as independent regional specialists like us. Choosing a local supply house means you get genuine, personalized service, including expert advice to guide you through complex repairs.
Do you carry fixtures that meet local water regulations?
Yes. Because California efficiency standards drive a strong demand for low-flow plumbing products, we stock a wide, readily available range of water-saving, code-compliant fixtures for any San Diego project.
