Scott , the sales person with McCowin was excellent and provided us the best and awesome service and advise. You're in good hands with these guys. The installer guy (Rudy) was also an excellent plumber. You can't go wrong with any of these folks. I highly recommend these folks to anyone who is in the market for a new water softener system.

Update - Issue has been resolved. The bitter taste was from the mineral filter (Very strong). I was looking for Costco bottle quality water with some minerals, but the mineral filter adds a VERY significant amount. The Salesperson stopped and removed the filter, and tested my water. McCowin water made it right, and offered to credit me for the mineral filter. I have had my reverse osmosis system in place for about a month now and all good. ———— Installation was good, but my review has to do more with Scot the salesperson. I received a text from him following up on the install and responded with several concerns. 1st) Water from the reverse osmosis was not crisp, and I told him it had a metallic taste to it and did not taste like Costco water, which he assured me that it would and was the major selling point for me to purchase this system. When I contacted Scot later that evening to discuss my concerns, he told me that the water would not taste like Costco brand because I chose to add minerals back into the reverse osmosis water and that if I wanted to spend more money to get the water to a Costco taste level I could. He also told me while making the sales pitch that he would come back and do a test of the water to make sure it was to my liking. When I asked about the test, he said that he was not available and had no idea when he would be back in my area. Then he abruptly ended our conversation without really addressing my concerns by saying bye, have a good evening. For peace of mind, I purchased my own water test kit/strips. I found that the water appears to be safe but it still tastes as if the metal is in the water. Be aware and be skeptical, do not just take the salesperson's word for it. If you do decide to purchase, do an independent before and after test to make sure you are getting what you paid for and requested. Once they install the system, they are on to the next.

I called several different companies. Scot the salesperson wasn’t pushy at all. I didn’t feel like I was being lied to like other companies. It’s been 3 days since install and Rudy the installer was great. The company called me to see how I liked my system(sorry I missed the call), the sales person Scot sent me a message making sure I was happy. I am very pleased and would definitely recommend McCowin to my friends and family.

I wanted the best soft water system available. After my research I determined that Hague was it. I reached out to Brian who took the time to come to my house and explain the advantages of the Hague system. There was no pressure or hard sell tactics. He stayed in touch via email and when I was ready to move forward I contacted him. Now, a year after installation, the system has been running flawlessly. The install was clean and fits nicely in my garage performed with attention to detail.

They installed a soft water system that we are very pleased with, and even when our tankless water heater was not working after the water soft install later that day, Brian came out to our home 9:00 at night to see if he could resolve the problem that turned out not to be related to the new water system, Talk about customer service!!
