    • Q:

      For kitchen sink water filter instalations, can you cut an access hole in a granite countertop if required?

      A:

      They did it for me in quartz so I assume the answer is yes.

    • Q:

      A C-55 license is required by California to perform water conditioner installation, do you have the C-55?

      A:

      We are licensed for all plumbing and water filtration with a C-36. Since we possess a C-36 full plumbing license, our installation services do not require a C-55 water conditioner license . California State License Board is an excellent resource… more

      A1 service and very cooperative and very knowledgeable staff. Forrest came to our home and did an amazing job at installation of water softener and also fixed our broken main water valve at no extra cost!! He also explained all the stuff of how the water softener works etc. He paid another visit to carefully brace the water softener tank to the wall for safety . Highly recommend their service!!

      This is my third year with their whole-house filtering system. Every year, they come to replace my filters. They reminded filter timing in a very polite way (not pushy way) and responded quickly when I asked them to schedule my filter replacement.

      Today, it was Devon who came for the service. Devon was very polite, nice, and quick to work. This is no-shoe house but he removed his shoes without me nudging him and communicate really well about what needs to be done to make sure my system keeps running. Great services.

      Devan Edmonds was very professional and nice. He was prompt and courteous.

      He explained the process of what needs to be done after the filters are changed.

      We are very happy with his service and highly recommend him.

      Thank you Devan.

      I will never use this business and would share the same with neighbors, friends and coworkers.

      City Water Filter replaced my filters on Monday (2/5/24), and caused a water leak, which I reported the same day. After much back and forth, they scheduled a fix for Saturday evening (2/10/24). As one would normally experience, I expected them to take full responsibility and make things right. However, to my surprise, on Saturday they came in expecting me to pay for the full system replacement. This didn't seem right to me and therefore I rejected the proposal. They left without making any fix.

      I have honestly never had this kind of experience with a small business. I wouldn't have worked with them in the first place given there are 10s of other businesses rated much higher on Yelp. I kind of inherited them from the previous home owner and forgot to do my due diligence.

      I've paid them $640 for the filter replacements, and am left with a leaky water filtration system.

      [Edit]
      I found another Water Filtration Business, who fixed the leak! It was the automatic shutoff valve, which they replaced for under 200! This goes to show that the 5 year warranty is a farce. Just find yourself a trustworthy business and try and maximize the use of resources.

      Updated review

      Scam Alert!

      City Water Filter (CWF) installed our water filter 2 years ago. We chose CWF because Chris came to our house, talked intelligently about the product, did a hardness test and told us we didn't need the full-fledged water softener as our water was not hard. The price CWF quoted us for their system was the same as the full water softener from a competing vendor. We decided to go with CWF

      Later we found out from San Jose Water that our water in Almaden is as hard as it gets. We even verified it with a water hardness kit and sent the results to CWF. However instead of acknowledging their mistake they wanted to charge full price to upgrade our system to a full water softener. And this after their own technician admitted to us their partial softener system doesn't work in our area

      Totally unprofessional behavior and not something you expect from a company dealing with something as important and basic as water quality

      PS we had chosen clear glass for one of our showers. The entire thing is ruined and has water stains now!!

      Beyond infuriating. Since installing two years ago, they sent people who didn't know how to do the work. Last week, Fernando showed up 20 mins late and told me he's not moving anything in the garage and not moving anything back and asked me where the water shut off valve is. How am I suppose to know? No one told me to move anything. He said we'll need to reschedule. The lady who rescheduled me, I asked if I need to do anything to prep for the reschedule or move anything around. She said no, they'll do everything because the owner will come himself.

      Day came, owner had to cancel and they rescheduled me for today. Fernando shows up. 45 mins late. Moves around everything in my garage, tossing the filter plastic wrapper on the ground, everything wet. I didn't check the garage since I wrote him a check inside the house by my kitchen. Everything was left a mess. I paid $633 "with a discount" clay said, for a membrane and filter change. I called clay, the owner, who said he already gave me a 10% discount for not paying cc and "at least it got done". He also said he doesn't know what my garage looked like beforehand. I said well, I saw Fernando taking pictures in on the camera beforehand.

      They didn't tell me Fernando was coming today. Clay said this is his only guy right now to service things. I'm so furious at how this all turned out.

      Worst decision ever to go with city water filter.

      Don't do it. Seems like fake reviews on Yelp. Apparently he incentivizes good reviews on Yelp for employee bonuses.

      Thank you Devan for a fast, efficient reverse osmosis water filter change. Really appreciated how he kept our place clean during the install and explained each of the new filters added, plus sharing how much our old filters had filtered out. Thanks Devan!

      we were recommended to Clay (owner). He came out and walked us through the system and we decided on the spot to proceed.

      We scheduled the installation, Larry and his son (Larry) showed up. They were amazing and did an incredible job and kept things clean and tidy. Larry walked us through the installation, and afterwards explained what ne to be done.

      High recommend City Water Filter.

      I would give 0 stars if possible. The receptionist quoted $150 on phone for changing four filters on my reverse osmosis filter. I wasn't home when they showed up on a time not agreed upon. My husband was home but he didn't know what was being serviced. They ended up charging him $420 for changing 4 filters which are $20 each at the most and which took all of 15 minutes. When I called the owner, he was rude and not ready to send us the break up of parts and labor and asked to not call him again. Avoid this business if you can.

      This is the type of customer service this company provides.
