Diamond Pure Water

Great water you honestly after trying it for a month and drinking only this water you notice a big difference when you drink other/​tap or other filtered water/​bottled water.

I buy water here every 3 weeks to refill 9 gallons of water jugs. This water is the purest you will find; only H2O comes out of the faucet after this company filters the water, and it cost me less than $ 5 each time I go in to refill. Also, they sell water containers and jugs that are BPA-​free for a very fair price. The owner and employees here are also very caring and respectful. The guys always take your water out to your car for you, and will talk to you about the water filtering process if you are thirsty for knowledge about your drinking water. Doctors recommend this water to their patients and I recommend this water to all of my family and friends.

Excellent product at great price, good and friendly customer service. Knowledgable too.

The water is filtered through reverse osmosis and it tastes great! Price is reasonable. Highly recommend getting your drinking water from this place!

Simply awesome! The best water ever and awesome customer service! My only warning is that you will not be satisfied with drinking ANY other water after you have had theirs. As others have said — it is SO refreshing!

Thank you every one for your input. I will try this place tomorrow!

When we run out our entire family misses it and urges us to return for a refill — typically 5 bottles at a time. Best water it town. Taste it for yourself, you will be back.

Love this place. The employees are very friendly and helpful, and their water is clean and tastes great.

Finally went in the other day to fill up some bottles for water. I had the pleasure of meeting and speaking with the owner and he gave me information on their process and who some of their customers are. I can definitely taste the different between tap and bottle waters and the water from here is the cleanest and most refreshing.

I use their RO h2o for our 200+ freshwater aquarium. I find the conversations from the owner quite animated and mostly entertaining. I recommend this place all the time.

As good as it gets. Best water on the planet

Delicious… and I wish they would expand their locations. Hint: Berkeley!

This place is the real-​deal!!!
If you want really great water that is as good as it gets, this place has it. Not only does it taste good, but it really is as good as it tastes. They use an eight-​step filtration process to kill and filter nearly everything in the water to get it down to a 98−99% water purity. They’ll tell you that no one else in the Bay Area does this and they say that they’re the only water company monitored by the Food and Drug Administration.
I’ve worked in water quality before and the main ingredient to their process really is their reverse-​osmosis. The other stuff is great, but the R-​O is the key here.
On the other side, the customer service is excellent and the water is extremely reasonable, about $ 3 to fill a 5 gallon Alhambra bottle. You have to fill it yourself, but they have carts to wheel it to your car.
Well worth it!

Customer service has always been great and the best purified water I’ve tasted. I grew up in Philadelphia and there was a natural spring 3 blocks from me. Spring water for free! Little did I know what kind of commodity it would turn into. Diamond Pure is the next best!

Outstanding customer service. Great prices and really good water. I was skeptical at first but now it is the only water I drink. When I travel I even take a bottle with me.
How’s that for conversion.

We have been getting water here for probably 12 years and I am spoiled. Absolutely the BEST water around. Doesn’t need to be refrigerated. Zero after taste and I completely trust the purity. It is a 15 minute drive from our home, but worth it. We just fill several 3 gal. dispensers with each visit. John and Jim offer the best service (and conversation) and always help me filling my containers and bringing them out to my car. After all these years I consider them to be friends.

I am very impressed with the customer service at this place! They are always genuinely friendly and insist on carrying/​loading the jugs for me.
The water is much cheaper than bottled water and tastes fine.

I LOVE this place! It’s self-​serve. The water tastes amazing! I would compare it to ‘Fiji’ water. You can’t beat the price. I have been going here for over 15 years and will continue to do so. I highly encourage anyone I know to go. I’m super picky about water, this place is great!

The water is great. I’ve talked to a few neighbors who also go here and they agree. It seems like a silly rave, but their reverse osmosis water tastes better than other places I’ve been. I definately like their «RO» water better than most «Spring» water you’ll get at the store.
By and large, I’ve found the staff helpful and friendly. Unless they were busy with several other people in the store, they always offer to help me load water into my car.
Typically conversations are on vanilla subjects (weather, local events, etc…) like you might expect in a retail enviornment. Occasionally though, they’ll get off onto some political rant or another. Even though I am usually sympathetic to their standpoint, I’m often surprised at how strongly they feel on a given subject. This seems to be the case with both the owner and the other guy who usually works there. Nice guys, but not what I am used to — perhaps I’m just too used to everyone walking on egg shells and trying to be politically correct.
They used to stay open until 7pm some nights, but I gather they didn’t have a lot of business for the last hour those days. Now they’re open till 6pm M-​F (shorter hours on Saturday and closed Sunday). That can make it tough to get in on weeknights if you don’t work locally.
Even when it’s tough to fill my water bottles because of scheduling, I usually make the effort to bring them here.

This place has THE BEST WATER around!!! I’m VERY particular about my water and have tried everything on the market from Dasani to Arrowheard to Crystal Geyser. The water here is very clean tasting.
I’ve known a few people who were undergoing kidney dialysis and a few other medical conditions who were referred specifically to this place by their doctors. After months of drinking the water, their kidneys were in good shape.
I was also suffering from a lot of kidney problems and drinking the water here has definitely helped! Since I’ve been drinking the water, I haven’t had any problems and haven’t had to go to the doctors.
One of the owners who works there is a hardworking, serious guy. He’s a good guy once you get to know him.
