A-1 Plumbing Supply San Francisco

Great shop with great customer service. The owner spent a good amount of time hunting down an obscure tool to help me remove an obscure faucet cartridge, then helped me remove the cartridge, as it was frozen. They even had a new cartridge in stock. Will definitely be returning. Cute shop cat, too.

Had a kitchen faucet hose break and after trying a few different plumbing supply stores with no luck ended up at A 1, was warmly greeted by a very helpful and knowledgeable employee who was able to find the replacement for us. Thank you

This place is great! Very friendly and helpful staff. They even had a hard to find part that I had gone to several places looking for it.

I came here while doing a small DIY bathroom plumbing repair. I didn't have any experience with plumbing and was learning as I went. The guy who helped me was incredibly helpful, knowledgeable, kind, and patient with my basic questions. He helped me find the part I needed, taught me some things, and the woman who worked here even sold me a new part for half off after I broke the first one accidentally once I got home. Another big plus is that they actually had the part I needed in the first place. I'd gone to a hardware store and another plumbing store, neither of which had it. I will 100% come back here for any plumbing projects in the future.

these guys are the absolute best.. the nicest, friendliest and most helpful folks I've encountered with my remodeling adventure..they had everything on hand and in stock from several small copper fittings to large cast iron pipes with associated angles and brackets for everything.. They even had vent pipes and brackets and overflows and tons of 4 band couplers in 3 sizes...A1-Plumbing is a slam dunk when I need anything plumbing!
