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.
