All I wanted was a R/O bottle free water cooler (rented) for 1 room, the kitchen for drinking, cooking, other and not spend a fortune. CWS was my saving place. I called so many places. 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. read more

Don't know how to start, 1 year and 6 months ago, we had Phil come to do the entire water filter system for our home, everything was done perfectly, professionally, and with good customer service. Today the water leaked from a screw washer, I called Phil he was in another job and sent his brother over to take care of it. Perfectly done again. Sorry for this review beings overdue. Highly recommend! read more

Called multiple times and finally got Phil on the phone. He told me he will put me on the schedule for a day that he was available. I texted him my address and followed up multiple times without response. He never confirmed and never showed up. Very bad service and apparently doesn't need new customer or business. Horrible. Found another company to do my water system and they were prompt and very responsive. Avoid this company. read more

Phil and his brother did an excellent job on installing a whole home water softener and RO system in our house. I could not recommend him more. The thing that differentiates Phil from others is his mantra that he would never install something in a customers house that he wouldn't in his own. Throughout the entire process he not only answered our questions but also gave tips about completely different items to watch out for in our home, for example a rusty looking pipe and unpainted pipes that he recommended long term to get painted to prevent rust. He set us up with a beautiful system that even matched our matte black fixtures and now our water is amazing and I could literally feel the difference with our hands. Please do not hesitate to reach out to them if you are looking for honest, trustworthy service from professionals who really know their stuff! I have recommended them to all my neighbors. read more

Although they are very busy and you may need to schedule out about 2 weeks+ before they can help install a system for you, it's worth the wait. I had our water softener system installed along with the water conditioner and a reverse osmosis drinking water system that has remineralization(important). The three brothers did an amazing job. A dominant competitor in SGV will use Puronics system which after some research, I would highly discourage. CWS uses Pentair/Fleck which are amongst top tier. Their pricing was actually lower then what the dominant competitor used for a higher quality system and work done! read more

We had our water softener and conditioner system installed by Phil and his team. Phil was very responsive, professional, and knowledgeable. He took his time to explain how the system works and answered all of our questions. He did not try to upswell us on anything and was very honest, which I appreciated. The team wore masks during COVID-19, and were very safe and professional. After having our system for 3 weeks now, I can see a complete difference in our water quality- from the drinking water filtered through our fridge, to our clothes, skin, and hair. I am loving it! I would recommend CWS, Phil and his team to everyone who asks! read more

So....

Phil is THE MAN! I wish more businesses/vendors could be like these guys! As a first-time homeowner i knew i wanted a water softener for my newly renovated home but was frustrated and lost in my search for an installer - especially since I needed one installed on the exterior of my home. I called plumbers, handymen, and "Big Softener" companies like Culligan. But they were all so expensive (marked up) or untrustworthy in their practices. I was at the end of my rope until i found CWS on Yelp. Enter Phil: friendly, informative, no BS, straight-to-the-point, and TRANSPARENT. From the get-go he was extremely upfront about the equipment, prices, and what to expect on the low to high end - and never tried to unnecessarily upsell me. One good byproduct of my endless search before CWS was that I gained a lot of knowledge about equipment and the "softener biz" and it was clear that Phil's quotes were extremely fair and reasonable. I was pleasantly surprised by the fact that his prices were not much more than just buying the equipment on my own (except with CWS I get a professional installation). Installation day was smooth as softened water - Phil's crew was friendly, quick, organized, and always communicative. One last thing: these guys are young and knowledgeable. I mention that because they are not like the "salty" old boomers who see uninformed customers as easy targets. The CWS guys have a "disrupter" vibe (like in the tech industry) who will hopefully take Big Softener down! Forget Culligan, Lifesource, etc. who all try to "hook" you with constant maintenance calls. CWS is who you're looking for if you want savvy, easy to talk to, fair prices, and high quality! read more

I had both water softner and water filtration system installed by Phil about 2 months ago. I waited until now to make sure everything is in working order before I write up. I was really impressed with his workmanship and professionalism. He took time to complete the job, clean up after done. One time I saw too much water in brine tank. I texted him and within 30min he showed at my door to check it out. It turned out there was nothing wrong. I highly recommend him if you ever want to put a new system in your house. read more

Stop looking for other companies. You've found the right one!!! I promise you, Custom Water Systems is the way to go! Phil has been amazing, and has gone above and beyond. I got a water softener and conditioner, plus an alkaline system for the kitchen. I contacted Custom Water Systems. Phil responded and came to my home for an in home consultation. He's knows his stuff, and is more than willing to pass on the knowledge. Felt good vibes with him, and scheduled an install date with him. Phil was on time for the install and completed the work per his time estimation. A couple weeks later, there was a small issue with one of the tanks. I emailed Phil about it and he came the next day to take a look. Turns out a sensor was malfunctioning. He swapped it out, and everything has been working great since. His prices are comparable to other companies. We shopped around with 2-3 other companies. Phil's was #1, hands down. Value + the best customer service of all time.....priceless. read more

We can't be more happy with our new softener and conditioner system from CWS. We also got the reverse osmosis/alkaline drinking water and wow! So worth it. Phil and Mike couldn't have been more helpful with questions we had as well as their work is top notch! I'm not sure how we've lived this long without soft conditioned water. Thanks CWS! read more

Phil and his brother Mike are great! They're not trying to upsell you... They're honest, straightforward and provide quality components. I did a lot of research on parts, suppliers and systems and Phil came in quoting me exactly (without prompting) the solution I came to and at a very competitive price. His installs are straight forward and sensible, making it a pretty streamlined process. Be aware, Phil uses legit "name brand" components in his systems, not cheap buy it off Amazon parts; especially with the RO system. Overall, it's been a year since I've had it installed, no problems and super happy with my choice of going with Custom Water Systems read more

Excellent service from these guys -- impeccable performance and competitively priced. I would highly recommend them for install, pricing and service! read more

I CAN'T RECOMMEND CWS ENOUGH!! I just moved into my condo and I was sick of using a Brita water filter so I decided to look into getting a filtered drinking system installed. Phil was responsive, courteous and informative and I was sold right away. The price he quoted on the phone for a filtration system + alkaline was the best that I've found in the local area by far and the choices for the hardware were elegant and tasteful. Phil was able to fit me for installation the NEXT DAY. Mike (Phil's brother. CWS is a family business!) who came to install the system was punctual and followed all Covid protocols. He was also very respectful of my house by wearing booties while inside. Mike promptly installed the system and thoroughly explained how the system works and the maintenance requirement. Working with CWS was one of the most stress free experience out of my recent move and it was awesome receiving the highest level of service at the lowest cost. Would recommend to anyone. read more

Found CWS, randomly, after having called a couple places for a new install quote. I called and spoke to Phil. He came out and provided a great quote and I could tell he was a good person, and immediately knew I'd use his company for the install. Phil was always on time and great at keeping in touch. Not a pushy salesman or anything and answered all my questions and addressed my concerns. I can't say enough about CWS and have already referred several people to them. You won't regret using them for your water system needs. read more

If you are investing in quality, Phil and his team are who you want to install your water softener. They are honest people and family-operated. Phil took the time to explain and walk me through the details. He gave me options on where to place the tanks and unfiltered faucet. Beautiful piping with precision! My dad does not compliment people often but he was amazed with their work. Thank you, Phil! read more

Phil and his team are great! My water softener stopped working and the company that installed it has since gone out of business. Most of the companies I called for repairs were only interested in selling me a new system. When called Custom Water Systems and Phil listened to the issues I was having and the type of system I had. He agreed that it was well worth repairing and in many ways thought the system I had was a bit of over-kill for a residence. At the end of it all, they were able to repair my system and bring it back to new condition for approximately 50% of the cost of replacement. Additionally, due to scheduling issues they had to come out on Christmas Eve. I would highly recommend them! read more

I had an emergency problem at my home in Buena Park with an old system installed by someone else. Phil was able to come the same day to fix it. He was efficient, friendly, did what he said he would for a reasonable price, and didn't try to sell me anything extra. I would have no hesitation to call him for repairs, or for an entirely upgraded system when it's time. He knows what he's doing. He wore a mask and followed Covid-19 protocols the whole time. Highly recommend. read more

Wow. Phil and his team did such an amazing job and at a very fair and reasonable price. Right off the bat, you can tell Phil was an expert in his field and that he was going to get the job done right without any headaches. Needless to say I'm glad I decided to go with CWS. I can't recommend these guys enough. read more

I saw the good reviews on yelp for Phil at Custom Water Systems (CSW) and decided to give him a chance. Phil was very friendly and informative when he came out to look over my old water softener system. I informed him during his visit that my old system had malfunctioned spewing resin throughout all my home's plumbing and that I wanted a new system that would prevent this from ever happening again. Phil came up with a plan to redo my system so this would never be a problem ever again. Everything Phil installed was professionally done. You can see from the photo that his work is top shelf and very clean. His pricing was fair and the filter and water softener equipment he installed was top notch. Thanks Phil for putting my system back in proper working order. read more

If you need a water softener and/or conditioner installed, look no further. These guys are not only extremely knowledgeable in their field of work, but they're also honest. After hours of research, I decided to "shop" around and luckily came across this company. Phil took the time to answer all my questions (I'm a research queen when it comes to any product). We decided to get both the water softener and conditioner. Couldn't be more satisfied with it. No more worrying about chemicals and hardness in our water. Customer service was exceptional and their prices literally can not be beat anywhere. This company far exceeded all expectations. Super clean work. Definitely recommend! read more

Phil responded to our Yelp inquiry very quickly and spent some time with us on the phone to assess our needs. We were able to agree to a time for him to come out for a full quote after the initial conversation very quickly, and we were also able to agree to an install date within a very reasonable timeframe. He has been super thorough and lightning fast to answer any questions we have had since the install, and we are very much looking forward to working with him and CWS on servicing our new system in the future.
