Incredibly helpful and knowledgeable staff. I saved a few hundred dollars by fixing a small leak myself.

These guys were great. When it came to helping me find the parts I needed they came through. I needed a brass pipe and I showed them some pictures of a Keurig coffee machine and the 1/4 inch pipe that needed. They ran to the back and grabbed me tubing and the connecting piece that I needed.

Outstanding customer service and professional advice.
Go to place for quality plumbing supplies.
If you are trying to avoid ending up with a poor, way overpriced plumbing ""contractor"" job by doing it yourself - this is the place for sure.
They'll point you in the right direction for connection and fitting solutions.
Consult youtube first so you'll have an understanding of your job. How to do everything is on there.
Take a bunch of good photos of what you're working on so they'll understand what you're trying to accomplish.

After reading this review, go immediately to your hot water heater, drain it and change the anode. It's on youtube. Or else - you'll get to learn all about installing a new water heater - and they're freakin' expensive these days.

Awesome mom and pop store. Peter and Angela are awesome, friendly and they're very knowledgeable. We go to them first to buy everything plumbing before going to the big box store.

Angela is so helpful and kind. I stopped in for a sink part and even though I couldn't find what I needed, she spent the time to help me troubleshoot. She even recommended a great service provider, James & James Plumbing, who was the perfect fit for the job. I trust this business and appreciate their customer centric approach and expertise.

Thank you! Great team and availability of parts for a broken shower mixer cartridge. I checked online and no luck. Your store had the Grohe part and even a generic one.

Looks like I found a new supply place for plumbing!!!

Needed a cartridge for an American Standard shower faucet. Called three plumbing supply places with no luck. A-1 came through. Very helpful, friendly staff. Everyone wore a mask.

Our sink and shower faucets were broken so we went to three hardware stores to ask if they had the part. A1 plumbing supply went above and beyond, out of all three hardware stores and tried to help us find the a similar part. Ultimately, they didn't have the part but really appreciate how the manager went above and beyond!

Peter and Uriah are GREAT. Plumbing company I work for has a account here so we get all of our stuff from A1. Customer service is exceptional and they always have the plumbing parts we need, and if they don't they always can get. Thank you Angela, Peter, and Uriah.
