I've visited this shop several times and always had a great experience.

The store also displays a water flow diagram showing the cleaning process (AG and carbon filters, a 5-micron pleated filter, reverse osmosis, ultraviolet disinfection, and an ozone generator.) They also sell various empty water jugs including a heat-resistant 5-gallon jug for $18 and a plastic 5-gallon jug for $13. One of the staff members mentioned that the owner is Taiwanese. [Price] * Purified Water = $0.35 per gallon * Alkaline Water = $1.25 per gallon [Pros] * Very friendly staff and the staff assists customers with carrying water jugs back to their cars * One of the more affordable alkaline water options I've seen [Cons] * The few designated parking spots are sometimes completely occupied and the parking lot is small, so customers may need to wait for a spot to open up Overall I am a big fan of this water shop - friendly service and affordable pricing on alkaline water.

I'm still recoiling in horror as I write this…read more We've been using Phresh for alkaline water delivery for about 3 months and have enjoyed the convenience. But while my husband and I were changing out an empty 5-gallon bottle, we noticed a white, thumb-sized fleck floating at the bottom. At first I assumed it was just a piece of plastic from the cap, so we emptied the bottle to check. To my absolute horror, it was a slug. We had been drinking water from that bottle for the past week with a SLUG floating in it. I gagged immediately. It was absolutely disgusting and alarming. Another reviewer mentioned finding a paintbrush and pencil at the bottom of their bottle, and I wish I found that than this. How sanitary is their bottling and quality control process if a slug can end up inside a sealed bottle unnoticed? I'm still sick over it. I wish I had taken a picture, but I was so disgusted that I immediately dumped it down the sink. Going to refill my own water from now on, at least I can see the cleanliness with my own eyes that way.

They only serviced the entire house or their R/O b/f water cooler standard or deluxe model (if they had water coolers) had to be purchased, they didn't rent. If they rented the monthly and install rate for 1 room was insanely high. Then I called CWS, talked to Phil, friendly helpful guy. Gave me unreal affordable quotes. I had to repeat back to be sure. They had various R/o b/f water cooler models. Standup unit or counter. Set a quick install date, Phil came and answered all my questions, showed me around the R/O b/f water cooler, the filters were inside the cooler. Who knew? Didn't have to go under the sink. The landlord wouldn't allow the R/O faucet install. Everything was great. Phil cleaned up. Made sure his install was fine even though he had another big job in south OC yet to drive to after my job. I was in IE. I highly recommend CWS to those who want filter clean water for just their kitchen fellow Yelpers. My cooler has 3 settings. Hot, cold, regular. If you want a Rental standup unit ask for a 'new' one. They'll know what you're talking about. My roommate will especially use the regular temp setting for her sunroom full of plants. I'm sure they'll (plants) thrive & be happy as I will. Call (CWS) them today. They're very friendly and courteous.

I'm put on hold for an hour after I tell them I'm not a new customer and the system cannot find my account. Now our machine is not working properly, so we can't use the little bit of water left. After 43 minutes of waiting today, I spoke with a very rude Maz of customer service who told me they have gone through a system upgrade and my April 17 delivery would now be May 9 and I would need to request a credit for the previous month. She also told me to use my time while waiting online to multitask and use a different phone for conference calls. This is not ethical. I will be reaching out to Costco Senior Buying Team whom I have the account through to let them know how their members are being treated.

I was then left with three empty 5 gallons that I needed picked up. I'm already on my third time requesting a pick up and they have still not come! I even spoke to an agent who guaranteed someone would come, and nothing. I get a notification every time that someone came to pick up the empty gallons, but they are still here when I get home. Completely disorganized and terrible customer service. Having to reschedule it for a fourth time is ridiculous. Will never do business with them again.
