I've reached out to several companies but none of them was as straight forward and reasonably priced as these guys! I spoke with Raymond first then Joseph after when I was ready to proceed. They explained everything easily and to the point. We had our water softener and RO water filtration (under sink) installed last Thursday and what a difference these it has made! I love how soft the water feels and you honestly can feel the difference when washing your hands and showering. I wish we got one sooner. Btw, I had some questions afterwards and they answered everything patiently and friendly! I hope this company continues to grow and expand because their service and quality is great and I hope this review helps more people make their decision with going with these guys for their water softener and drinking system needs!

Rene and his installation team arrived on time and completed the install efficiently and professionally.

I'd highly recommend Supreme Water to anyone looking to install a salt-free water treatment system.

Quick update since I've received a couple private messages from a few folks…read more I had another Hague authorized dealer come out to take a look. The issue was caused due to the prior service from McCowin. The technician had completely opened the blend dial so the soft water wasn't making its way to the inside of my home. If you're looking for a local Hague alternative to McCowin, I highly recommend L.A. Purification Products https://www.socalpurification.com.

I called 3 whole house water companies, and Diamond Pure was very responsive. Oscar gave me quotes…read morevia text within minutes of our verbal call. He came out to our home to determine if the house had separate lines for the house and the yard, (in which case it does). He also determined the house used to have a system and told me it would be a reletvely easy install as the regeneration waste drain was right on the other side of the wall of the garage where the soft water and chlorine filter tanks will sit. I also got a Reverse Osmosis system under the kitchen sink. A tech came out to install that. That took 30 minutes. Another tech was scheduled to install the garage tanks, but could not make it. Oscar kept the schedule promise and came out himself for the scheduled time and happily installed the system. What a fantastic team to keep the scheduled install and have the Sales Person, Oscar, come out to do the install, even though he has "retired" from installs and moved into sales. Everything was installed with professionalism and cleanly done. I had a lot of question for Oscar during the install, and he took the time to answer them.

This was honestly one of the easiest and best purchases I've made. From the beginning, Mike was…read moreextremely helpful and professional. 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.

I had a reverse osmosis system installed under our kitchen sink a month ago. Scheduling was easy,…read morebut the technician arrived late and seemed to be in a rush. Later that evening, we discovered the kitchen sink pull-down sprayer was blocked and unusable. We had to contact the technician to return and fix the issue. A couple of weeks later, I noticed that a screw from the installation had penetrated through the back of our kitchen island. This is sloppy workmanship and now requires another repair. We have young children in our home, making this a safety concern that should never have occurred. These issues could likely have been avoided if the installation had not been rushed. While the initial problem was eventually corrected, the damage to our kitchen island raises serious concerns about the quality of the work.

Their flat fee price was very reasonable. Erick came to my house and did a beautiful job on my kitchen faucet. He went above and beyond the call of duty and ran to the Home Depot to obtain two extra 3/8" to 1/2" adapters (which were unexpected but required to finish the job that day) as I was hosting a party at my house the next day. Dedication and service like that are hard to find these days and I certainly appreciated his efforts! I would highly recommend him and Olson superior plumbing will be my first call should I need plumbing help in the future!
