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.
Matthew A.2 years agoQ:
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

Larry and Larry installed a sediment filter, carbon filter, water softener, and reverse osmosis system for us this week. Our new construction had a dedicated closet for the water purification system. They were professional, thorough, and capable. Larry talked me through the installation as he worked. The install was very clean and went smoothly. Larry did an excellent job cutting a hole in our kitchen countertop and installing the RO faucet. We are very happy with City Water Filter.

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.Helpful 0Thanks 0Love this 0Oh no 0 - Soheil M.San Jose, CA25131Mar 22, 2024
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.

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.Helpful 4Thanks 0Love this 1Oh no 0Business owner information

Vishal didn't have a warranty with us ever since you weren't original customer of the equipment and it was over 5 years old outside of warranty. He inherited our equipment when he bought his house. The prior owner was an original customer of ours. Many times, when we get customers that don't share our common priority for high water quality like Vishal, the customer can make demands on us that our outside of normal business requests. Even though we try to satisfy his frustration with reasonable response, he plays games and doesn't have integrity for his actions.
Let me explain:
Vishal's negative review lacks some important information that give's context though he knowingly left it out. We warned him BEFORE the filter service that his warranty was over and advised him that he needed replace his system. He signed a waiver of liability before we serviced the equipment meaning that he was aware that his equipment was out of warranty though we would service it anyway. CWF provides a 5-year warranty on our reverse osmosis systems. After we changed the filters on the 6-Stage Reverse Osmosis, we couldn't get the system to stop leaking where the housings came together. We advised him that he should have replaced the system when we warned him before servicing. He agreed that he had made a mistake. We gave him the option to replace his system at a discount because he just changed the filters on the reverse osmosis. The discount was equal to the filter service cost on the reverse osmosis only. Once again in his review he is dishonest in representing the the filter replacement was approx. $600 when it doesn't take into account the filters on the whole house that were replaced. To add insult to injury, he scheduled for us to come to his house to replace the reverse osmosis and some other housings in the garage that were out of warranty and he refused to let us do the service to replace the items that were out of warranty. He acted very childishly like he was getting revenge on us or something like that. I simply told him to never call me again. - Man M.San Jose, CA17105Jul 17, 2024Updated 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!!Helpful 0Thanks 0Love this 0Oh no 0Business owner information

That is awesome to hear that you had a great experience with City Water Filter Corporation! Our team is always hard at work making sure our customers have all of their questions answered and receive the best possible service. Thank you for the feedback and have a great day!
Feb 2, 2021Previous reviewRecently used City Water Filter to install a water softening system and RO system. Both Clay (owner) and Forest (our installer) were very knowledgeable and helpful. They selected the right system for us and made sure everything was installed correctly. Special kudos to Forest who went out of his way to install the RO connection to the refrigerator properly (our crawl space under the house is not easy to navigate!)
Great experience over all ... - Sep 5, 2023
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.Helpful 15Thanks 1Love this 0Oh no 0 - Tiffany K.San Francisco, CA11086258Feb 13, 2024

Shot out to Technician Devan. Polite and arrived on time. And the filter change service is done fast.

The owner Clay is also very responsive to calls and questions. I will like to give 4.5 in total, 0.5 star off since the team can do better if they can have a better inside communication about the scheduling.

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.

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.

How would you even remember that a receptionist told you the filter service was $150 when you had your filter installed 2 years ago? We sent you a quote to change your filters two years ago for a filter system that you hadn't changed the filters for years. I gave you a discount to install a new system. Nobody ever told you the cost was $150. Never ever. All 6 filters were changed which included the membrane and remineralization filter. We already sent you the invoice to your email. We installed your reverse osmosis 2 years ago and you never bothered to change your filters. The filters should be changed yearly. Obviously water quality is not your priority and spending money on keeping your filters changed is not your priority since you seem to think my services don't have value. Considering you live in Burlingame I can hardly believe you cannot afford a filter service. All you have done here is lost a service provider as I will never come to your property again under any circumstances.
