Really great service. JAVI and Eric are really helpful and professional

Seriously? Needed something small & they charged 2x Home Depot & then tried to shortchange me when I paid cash! Beware of those who arent honest in small things...Shame on you Eric!

I have been getting plumbing supplies from standard/MWI supply for 15 years and they have always been willing to go the extra mile if they dont have something I need they will get it !!! Very satisfied with them

Called asked a question, he (Eric) immediately answered and then offered to find the part and measure it for me, that NEVER happens anymore, thank you!!! Then said it was on the counter waiting for me. On my way:)

Our experience with MWI Plumbers Supply in Oceanside, California couldn’t have been better. April Brennan, in particular, made our shopping experience exceptionally pleasant. We liked her immediately upon our initial encounter, and we were impressed by her knowledge, energy, personality, professionalism, and can-do attitude. MWI’s prices for name-brand faucets and accessories easily beat out the competition, delivery was swift, and their customer-service orientation is the best. We are 100% satisfied and happy to recommend MWI with no reservations. Thank you again, April!

Great place to find most everything for your plumbing

We were referred here by our plumber for a new construction granny flat and had the best experience. The showroom had plenty of product to choose from and our salesperson (April) was beyond knowledgeable and so helpful and easy to work with! Highly recommend taking your business here.

Talk to April Brennan at Standard Plumbing. Shes very knowledgeable & helpful.

I am so grateful I found April B at Standard, Oceanside. I had tried Ferguson’s and a few other plumbing supply showrooms and was a little frustrated with the lack of assistance I got. I was remodeling my home for the first time and I had a lot of questions so was probably annoying, but the moment I walked into Standard Plumbing, April explained and walked me through everything I needed. There was one mistake made, April recognized it immediately and corrected it within a day. Seriously, such a good experience. I bought all Koehler products for two bathrooms & a kitchen remodel.

Great staff every body there knows me. great prices and they have all the stuff i need im there 3 to 4 times a week to get the parts i need for clients. you guys are great. Victors Drain Cleaning And Plumbing Repair thank you 👍👍highly recommended

Great customer service! They are always happy to help anyone that may need some direction. Wonderful showroom!

My plumber sent me there with a list of items to pick up. April was awesome and helped me get exactly what I needed (I know NOTHING about plumbing)! While I was there, other contractors came and went quickly with what they needed.

The guys at the back counter are great. Great customer service. They saved me a lot of $$$ by listening to what I needed and showing me a more cost effective product that suited my needs.

This place should stick to wholesale instead of partly retail. Customer service is truly ignorant when it comes to customer needs. Parts are way over priced. Bad experience all around.

I have not tried to return stuff or get warranty service, but they cater to plumbers and building owners with $10 or free delivery. If you do will-call, they have Good free coffee. The home stores dont have commercial quality ABS (mostly PVC) traps, swept 90s etc while MWI does.

Not recommended for honest contractors!Lets SeeCall location - confirm itemAsk to hold and receive amount for checkDrive three hours to location - find out check amount is incorrectFind out - NO CC payments either via phone or formNo hold check for overnight of correct checkNo refund for difference of incorrect checkDrive three hours back with NOTHING in hand.Keep up the great customer service.Please treat contractors as customers and not credit card scammers looking to purchase a sampling well. ( I am sure theses scammers would resale a plastic well for huge profits) And just in case here is the part number if any one else would be stupid enough to scam a plumbing supply for plastic well. (SV24-L)I would also recommend informing accounting dept to understand that certain parts are harder to come by because of stock not the value.

Great staff and great service.Best professional supplier in the county.

April is awesome! Great ideas and customer service.

Very knowledgeable and service oriented, top-notch professionals.

Great staff VERY helpful even to non-professionals

HORRIBLE !!! These Guys are Lazy and Incompetent and unnaccountable . They dont want to honor any warranty service. My water heater was authorized by Rheem for replacement under warranty. They would not call Rheem to confirm the warranty authorization . Some guy named Larry said he called Rheem and then another guy took the phone and said they didnt call Rheem and said he would not honor the warranty because their system wont let them When I asked them what their full names were they started to lie about their names and all of a sudden everyones name changed, I spoke to two other plumbers afterwards who said MWI is terrible !!AVOID LIKE THE PLAGUE.. Im going to file a complaint with BBB !!!

Excellent Service from April in sales

Helpful
