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.

They need to move to paperless billing…read more We have a few business accounts with SGVWC. They do not offer paperless billing. I've confirmed that they mail the invoices LATE so that by the time they arrive in the mail they are past due. The available auto pay option is useless for companies that require invoice approval prior to payment. When I told customer service about the late billing issue they instructed me to send a request via email each month for a copy of our bill so we can get it on time. I did so, and unsurprisingly, they don't respond. We use several utility suppliers, all of which offer paperless billing and convenient online access to our accounts. SGVWC is the only exception.

I had done some research ahead of time and knew basically what I needed. Chuck came by and didn't try to sell us anything more than we needed. He was quick with testing the water, reviewing the space, and providing a quote. The quote was competitive and he answered all my questions with everything I was looking to understand. During the install day, the team showed a bit late but still made it. They got to work and did a very clean job. No mess and everything is neatly installed. All piping works for my space and doesn't require me to sacrifice my garage. The crew was professional and even made a wiring change when I requested. I couldn't believe they managed to get the equipment in the small space beside my existing shelves. I previously had an under the skin RO but decided to upgrade since mine was 10 years old. The new filtered water is great, not much better than the previous RO though. It does take significantly less space under the sink. The softened water is great too. I wouldn't drink it, it has a briny taste, but I've noticed significant improvements to my fixtures I'm trying to protect plus my hair feels so much nicer.
