Recommended Customer Reviews

I'm disappointed with the counter person he was short and curt as I tried to get info about my plumbing issues seemed like I wasn't important enough to take the time to resolve my problem.
The last time I was in there a couple of years ago he wasn't much different seemed like it was a hassle to help me hopefully this review will motivate them to review there customer service because the employees are the business it's all about service.
General plumbing Walnut Creek was just the opposite great service I will be doing business with them.

Needed some supplies and definitely needed some advice on my bathroom remodel. Bob went above and beyond helping me get everything I needed. His one on one advice and guidance was crucial. He saved me from making some very expensive mistakes.
This kind of service is why shopping small and avoiding the big box chains is always the right choice.
Thanks again sir!

Poor service from Luis Alanis Showroom Sales.
Luis may need to work on leaving his baggage at home or at least know when to give himself time off to get his attitude right for customers. Displayed very poor attitude towards me when I was just trying to get the right product needed. This was not necessary and will make me hesitate in ever going back.
Showroom was pretty cool with lots of variety and choices.
Once my product was ordered Luis said he would reach out to let me know it was there. That never happened. I ended up having to follow up with my order after the expected time frame passed.
I only say this to management/ownership. This high degree of showroom variety only does any good if you have the right people in place for the customer. It may be time to reevaluate Luis's role at your shop to maximize your investment and ensure he is in the best suited role.
We're talking basic customer service, without the nasty, unnecessary attitude and letting the customer know when there product has arrived as promised. We're expecting the basics at the very least. Thank you.

I do flooring. Was recommended this place from an Ace hardware person as they didn't have my part. I go in tell the guy I know nothing about plumbing. Show him the bathroom sink valves I have and need. He says ""what brand?"" I say I haven't a clue I just bought the house. I figure with all his knowledge, as he said it is probably one of these two types of water faucets. But I as a flooring guy need to know. He doesn't ask me any questions or anything to help try to figure this out. I say UCK THEM for the regular guy. I WILL NEVER ECOMMEND OR GO THERE.

Went to General Plumbing Supply for help/advice with an outside water faucet that is leaking. I was willing to purchase whatever they recommend but they could care less and were not interested in even getting up from their chairs. Will never return.

Nice store, plenty on display and I had a great experience working with Luis. I got a very nice Grohe kitchen faucet at a competitive price.

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.
