    I did a lot of research before deciding on Radiant Water to be the company to install my water purifier (Catalytic Carbon to remove chorine and chloramines - which eat away at your pipes if you have the Irvine Ranch Water - I don't want anymore pinhole leaks!) and water softener (I am so excited to have soft water for my hair, skin and also so my faucets don't look awful with all the hard water build up) and I am super happy with my decision! Unlike other companies who have salespeople who can't actually do the work themselves, the owner, Pat came out to teach me about my options and give me the quote. Then on the day of the installation, Pat came back to the job again to make sure everything went smoothly and was what we agreed on. The technicians Ryan and Brandon were outstanding! In all, having all 3 employees at my house I felt my job was very well taken care of and it was also finished in a timely manner while being done to the highest standards! Ryan has incredible attention to detail, and as a perfectionist myself, that is something that I really appreciate. All of Ryan's piping work is perfectly straight and as 'out of sight' as possible. I also appreciated that he made the smallest hole possible into my house to connect to my drain system - it's barely noticeable. All of the work is gorgeous and you can tell the precision and care that Ryan puts into everything he does! I wish all contractors operated at this meticulous, caring, high level, that Ryan does - he is outstanding! I also appreciate all of the time Ryan took to show me all of the work and explain about my system after he completed the job. Never once did I feel rushed and I was able to ask a lot of questions and he was very nice and helpful. Other water companies I interviewed but decided not to go with "mansplained" me (which was annoying!) but Radiant Water dealt solely with me (never my husband) and I was always treated with the utmost courtesy. Brandon was outstanding as well and did a great job installing my Reverse Osmosis system and new sink faucet in my kitchen. I also like how Radiant Water are technicians as well where they can do maintenance and also fix plumbing problems with my water system - unlike some companies who only instal new systems. I appreciate how they will send me postcards in the mail to check in with me to remind me that the filters in my RO need changed and they can come out to service the systems as well which makes things easy for me. I like how all of the parts are made in America and they have both a parts and labor warranty. Overall, I was very impressed with and happy with all 3 men from Radiant Water. They are all experts at what they do and at all times made me feel like a valued customer. They treated my home with care and made sure that they tailored the water system and installation experience to be exactly what I wanted and what was optimal for my home. I highly recommend Radiant Water! I think they are truly the best company out there for your water purifying and water softening needs!

    My broken filter for the softwater unit

    My softwater unit had stopped working probably months ago and I finally looked for help when I started noticing plumbing issues of water pressure getting weak, calcification around faucets and, finally, yellow pellets spraying out of the shower heads. Don't wait on fixing your soft water. Anyways, I called around and most companies either did not service softwater units unless they installed it or charged a diagnostic fee. Radiant water not only took my call after working hours but assured me that they would come out the following morning and there would be no diagnostic fee. Pat looked at my unit as well as the faucets and showers in the house. He advised me on what to do to clear the pellets and provided an affordable solution to my softwater repair. After a new filter replacement as well as some other minor parts, my softwater unit, which was probably beyond a decade old, looked good as new. So grateful to Pat and his team to take care of things so efficiently and, most importantly, honestly.

    Single unit Softener - works really well

    See all

I appreciated how he coordinated water shutoff and testing easily with us and was quick and efficient with his installation. All the plumbing was done cleanly and professionally and he took the time to explain maintenance and operating information for the softener system. Water quality is noticeably improved and we are very happy with the result!

Chuck has always been friendly and professional. He personally visited my home before the installation to test the water quality and review the plumbing layout with me to make sure everything would be installed the way I wanted. Martin G and Robert did an excellent job with the installation. They installed the water softener neatly in my garage, and I especially appreciated that they took the time to install a separate unfiltered water line to my backyard exactly as I requested. The workmanship was clean, professional, and exceeded my expectations. I highly recommend West Coast Water Filtration to anyone looking for a reliable and professional water softener installation.

He took the time to explain everything clearly, gave me all the information I needed, and answered every question I had without making the process feel rushed or pressured. I spent a good amount of time researching different water softener systems because I wanted to make sure I was getting the best system for my money. After comparing several options, I decided to go with Diamond Pure, and I'm really glad I did. The installation process was smooth, quick, and very professional. The technician showed up on time, worked efficiently, and made sure everything was installed correctly. He also walked me through how the system works and answered all my questions so I would know what to do if anything ever came up. What I really like is how simple and easy the system is to understand and maintain. Overall, the entire experience from getting information, to purchasing, to installation was excellent. I highly recommend Diamond Pure to anyone looking for a reliable water softener system and great customer service.

Water seems soft but it doeant seem to remove any other toxic elements no more or does less This was especially disappointing because they advertise that these tanks should last 5 to 10 years. Based on my experience, the performance declined much sooner than expected, and I did not feel like the issue was taken seriously or properly evaluated.
