    Been using products from MCS for years and it has always been happy with it. Best place to equip your house with clean drinkable water and other home water needs. Will be a continuing customer.

    Here you go!

    A reputable and trustworthy water softener and filtration company serving the Los Angeles Chinese community. We've installed their system in three different homes, and each experience has been smooth and professional. Great workmanship, clear communication, and reliable results every time. Highly recommended. 洛杉磯華人區非常有信譽、也很靠譜的軟水與淨水公司。 我們已經是第三棟房子請他們安裝與服務,每一次都很順利、專業又安心。施工細心、溝通清楚,效果也一如既往地好。 強力推薦。

    I have one good thing to say about this company, which is once the system is installed correctly it…read moreworks (not so sure yet on the system being advertised to clear up scale on the faucets just yet but I will update my review within 6 months of usage). Problems: 1. Sales person advertised that the system could be installed in the garage with no problem (mind you the actual techs were not present). - This was not the case as when the techs showed up, they indicated would need to dig across the entire property to install in my garage based on where my water main was located, thus my filter was installed outside which is subject to weather issues. They convinced me that they had some weatherproofing methods available and there would be a bypass installed in the event of freezing, etc. 2. The salesman (they will visit you) advertised that the technicians had all necessary tools to see existing structures/cables underneath the ground and if indeed they did hit anything they would repair it (to include sprinklers). - When the technicians arrived, they immediately started digging and asking questions that the sales person had the answer to the day prior. Puragain hit internet cables and sprinkler power cables. It took them 2 days, plus a couple of call backs (explain this in next one) to complete the installation. Installation was advertised to take half a day. Thus I spent New Year's Eve holding a flashlight to assist the team that was unprepared for the job. They arrived at 9:00am and left that night at 9:30pm. 3. Call backs: The technicians came unequipped to perform the work required the 1st time and tore up the yard during the installation. We called them out 3 times to pound back the soil and grass they removed during the installation. Additionally, they forgot to cut the water main back on after they claimed they were finished, thus we had no water flowing after about 5 minutes of trying to get the air out of the pipes as instructed. Thus they came back and cut that back on. Lastly, when I tested the sprinkler system, an immense pressure built up just underneath the filter and water blasted all the way up to the second story of my house (no damage to the house) but they had to come and fix that as well). 4. Sprinkler Issue: They were able to fix the pressure problem underneath the filters, reconnect the internet power cables successfully, but they severed my sprinkler power cables (~ $800), and still 2 zones in my front yard are not working. The ultimate worse thing is that Puragain said they would pay for the Sprinkler technicians required fixes (in writing). They have not paid a penny and it's been just short of two weeks in requesting a status on paying for an invoice to fix my two zones in my front yard and send us a check for the ~$800 when the service tech came out prior. The Heath TX City Manager, who is somewhat of an owner of Puragain, multiple responses to this issue has been that the invoice was sent over to Accounting (no payment) and that he had not heard back from Accounting. Bottom Line: I would never recommend this company to anyone at this time.

One of the companies I called was Diamond Pure Water and I spoke with Mike.

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.

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.
