    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 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

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. I'm happy with the purchase and experience.

I also called a number of other companies & it was clear they weren't interested in spending the time texting & on the phone with me that Mike did. He set me up with a great dual catalytic carbon filter (to completely remove chloramines) & a soft water filter ( to treat hard water & remove calcium & magnesium).

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.

When I told Tim, he asked how long ago it was bought, what the warranty was and specifically said "well we should keep it there, you should absolutely get your money's worth on it" and he installed in series after the filter. I spoke with multiple other dealers and two of them tried to get me to remove a perfectly functional water filter to sell me a new one in addition to the softener. So basically, he was honest, did the job, gave me a fair price, answered his phone when I had questions, followed up and was a legit good person to chat with and have in my home. And his assistant Andrew was great as well. 5 stars.
