Horrible horrible service I came to simply buy some pvc pipe and the bald hut was just plain rude . I asked no more than 3 questions and was rude and unpleasant , never coming here again recommend going else where

Worst ever. So much for supporting local businesses, off to Home Depot I go. I thought I'd give them a Second chance since the first time I tried to purchase a an adapter for a toilet valve, the bald guy said I had to purchase this specific valve he had and needed to buy his tool to remove it off the old valve but there was no guarantee it would work and if it didn't I could return the opened valve or tool. This moron thought I was born last night. I had previously replaced a valve (from H.D) in my other bathroom, but came here to again, support local business plus I didn't want to drive all the way to Vallejo. Talk about selling you BS. So this time I thought I'd go in again looking for a pvc female adapter. Bald guy again, anything else? I said nope. Well there's a $10 cash minimum on sales and you're at .46. So I said, Home Depot it is. I guess I didn't learn the first time.

Awful customer service. Came in to inquire if they had pex piping for a project that my wife and I are doing, but the gentleman at the counter seemed like he didn't want to give me the time of day. He said that they do ""professional plumbing"" and kept deflecting me to Home Depot, so I guess he doesn't want the business. I'm all for supporting local businesses, but if this is the kind of customer service that I'm going to receive for not being a ""professional"", then I'll take my business elsewhere.

I needed a flapper for an old toilet. It's a rare item and though they didn't have one in the store the lady said the owner had one at his house and I was welcome to pick it up! They even took time to send pictures! Who else does that anymore? It's not very often these days that any kind of company is really concerned about the customer and I was thankful to get that kind of service.

Called General Plumbing Monday morning and explained my situation. I had a stem extension that had broken on my hot water shower handle and I pulled the knob which had markings for a manufacturer who makes parts for several companies. The person on the phone said to bring in what I had and they had some catalogs to look through to see if they could ID the part. So I hop in my car and drive from Benicia to American Canyon parts in hand (including an unbroken extender from the cold water side) hoping I could get some help. However I walked in the door and one of the guys at the front counter takes a look at my bag if parts and abruptly tells me he can't help me if I don't have the brand and part numbers. I told him I had just called and explained my situation and drove in all the way from Benicia on the advice that they could at least try and help me and he just repeats himself. I asked if he was familiar with the manufacturer and he just says 'nope'! At this point I'm annoyed and just tell him that I wouldn't have made the trip if the person on the phone had just told me they wouldn't be able to help. What a waste if 45 minutes!
Oh by the way I stopped by another plumbing store in Concord who really tried to help me and guess what??? Found it, ordered it, installed it today and it fits like a glove!
I'll avoid General Plumbing from now on

Ellen is a star! She works in sales and helped us solve a warranty issue, even calling the manufacturers rep. She is very knowledgeable and professional. Very happy we sought her advice. We highly recommend General Plumbing Supply. They have a very nice showroom with lots of choices and obviously back the products they sell. Superb customer service!

Great plumbing supply store. Worked with Kenny on a high end master shower. Helped me with Philyrich Thermostat Cartridge. He is very helpful. No need to go anywhere else for your plumbing supply needs

Had to do some kitchen sink plumbing not only under the sink but behind the walls. Went to General plumbing and everyone was extremely helpful and sold us exactly what we needed....also explained some things to us. They were so helpful and didnt sell us anything we didnt need. Got the job done for approximately $50 and all is perfect!!

Ellen is great!
We were referred here by our contractor to select fixtures for a bathroom remodel. Ellen was our goto person and we set a meeting. In the course of an hour she helped us pick out everything we needed. She included all the items that were needed for the install, beyond the obvious fixtures. Very thorough and knowledgeable.
Good size showroom. We were able to see examples and do side by side comparisons. We quickly narrowed down the options and had it all set for our remodel.
Positive experience.
