Andiamo Plumbing

Andiamo Plumbing runs a plumbing operation out of Walnut Creek with a showroom that stocks hardware and supplies. Staff handle sales of plumbing parts including PVC fittings and other materials that customers seek for jobs. Griselda works with shoppers at the main spot and sometimes at the Brentwood location while Josh Vargas deals directly with hardware purchases. The business carries an extensive range of items that fill gaps left by big box stores.

Customers come in for bathroom remodel supplies and general plumbing parts. They describe finding specific PVC fittings after initial calls miss them in stock and buying thousands of dollars in hardware for projects. Some note that staff point out the right pieces when standard retailers fall short while others run into mismatches on sizes that lead to return headaches. Communication around those returns and confirmations can stretch out with delays of days before responses come back.

Work happens through the showroom counter where shoppers call ahead or stop by for stock checks. Staff answer questions on products and sometimes push to locate items even when first told they are unavailable. Service reaches into nearby spots like Brentwood for certain team members though hours and exact coverage follow what customers arrange on site. Pricing and returns follow the terms set on individual hardware pieces such as living finishes that complicate exchanges.

The outfit shows a Google rating of 4.4 from 186 reviews with feedback that circles around solid inventory depth and staff knowledge on one side and slow replies plus uneven welcome on the other. Positive notes repeat on the range of supplies while complaints focus on follow through during sales. DIRT Score 4.1 from reviews on Finds.

“Beautiful showroom. Knowledgeable staff. Griselda is amazing. She goes above and beyond. She’s normally at the Brentwood location, but if you can score an appointment with her, you are set.”

“This review is specifically for Josh Vargas. I purchased tens of thousands of $ of plumbing hardware from him and the entire experience has been an absolute nightmare. He is wildly uncommunicative, especially when I need his response quickly to confirm things, I'd call and call and he wouldn't pick up, and wouldn't bother to call me back for days. He also recommended a piece of hardware that ended up being the wrong size, but then wouldn't let me return it because it's a living finish, without taking any accountability for specifically recommending that size. Then my contractor went to bat for me and got him to agree to take it back, only for him to back out later when I took it back to them. After many many useless trips back and forth to deal with this, I'm done giving general plumbing supply my business. If you go to the showroom, my recommendation is to work with anyone but Josh.”

“I was told to come here to remodel my bathroom. I guess I didn't look the part as noone said hello or even acknowledged me. If you want snooty service maybe this your place otherwise I'll take my 75k elsewhere.”

“General Plumbing Supply in Walnut Creek has an unbeatable selection of PVC products—easily the best in the area. If you can’t find what you need at Lowe’s or Home Depot, chances are they have it here. I originally called ahead to ask about a specific PVC fitting, and they told me they didn’t have it. But when I stopped by to pick up some other supplies, I ended up finding exactly what I had been looking for. Their inventory is so extensive that even they might not realize everything they have in stock. Beyond the great selection, the customer service here is top-notch. The staff is knowledgeable, friendly, and always willing to go the extra mile to help you find what you need. Whether you’re a professional plumber or just tackling a DIY project, they treat you with the same level of respect and attentiveness. This will definitely be my first stop for any future plumbing supplies. Highly recommend!”

“The best place for the plumbing supplies! They sell everything for plumbing. Great customer service and support. I buy everything from them. Keep up a great work guys.”
