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'm very impressed with West Coast Water Filtration. They were quick to respond to my inquiry and…read morethen were willing to come by on a holiday to review our job. 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.

When the water purifier in my shop suddenly broke down, I contacted the original company that…read moresupplied it for repairs. At first, they proposed: $210 to replace the filter, plus $180 to install a new machine (the machine itself not included). I explained that I already had an unused backup unit of the same brand and model, also purchased from them. I only needed the old unit removed and the spare one installed, without replacing the filter. Based on their original logic, it should have just been the $180 installation fee. However, they changed their story and said that removing and reinstalling would cost $360 -- then added, "We can charge you $280." After that, they strongly pushed me to buy a brand-new machine for $700-800, with installation charged separately. The technician even claimed that removing the machine would cause continuous leaking because he "couldn't find the water valve," and that many parts would be needed for replacement. But the valve was right next to the machine, clearly visible. As a professional, saying he couldn't find the valve was hard to understand. If they had been transparent from the beginning -- for example, clearly stating $180 service fee plus $100 additional part -- I might have accepted it. But constantly changing the quote, exaggerating the difficulty, and steering me toward buying a new machine only made me feel like they saw me as an easy target. In the end, I handled it myself. The whole process took less than 10 minutes. No extra parts were needed -- just turning off the water valve, disconnecting the tubing, and reconnecting it to complete the swap. Sigh... I understand that every business wants to make money, but the way you do it really matters.

I just had to text him some photos of my plumbing system for a quote. And, they had the best price. The new system has been in use for almost a month now and so far so good. After booking an installation appointment, the technicians arrived on time and two technicians installed the system in like 2 hours (which is fast in my opinion). One of my neighbors bought a softener system and hired a plumber to install the system as a weekend side hustle and that guy needed like half a day. They take Zelle or check payments.

I have considered cutting ties with this company many instances ago but hesitant because it's…read moresimply easier to put up with them than start with a new company on the maintenance of our drinking water filter and soft water system, both installed by them. However, today was the last straw. They were very thorough and polite in the very beginning when they wanted the jobs. Once they got the gig the level of service declined and with each year it declined further. Communication is short and borderline rude, mainly Tony. They said they could come to do maintenance today at 3pm. It is now 10pm, no one showed up, no one called or texted. I was very respectful when reaching out to Tony too, in which every text was responded with a very blunt few words answer from Tony. It's very unlike his presence here on yelp where he spend much time responding at length to each reviews. Overall, very exhausting and disappointing company. I'm no longer putting up with this level of treatment.

Out of all the companies that gave us quotes during this process, Jason's was definitely the best priced, as well as not trying to upsell extra things we didn't need.
