To Costco, my review was for Eco Water System Company. I had business with it through your advertising. Therefore, I need you to know about it. Please, work with them to solve this issue. This company installed Eco Water system to our house twice. The first system was good. The second system was "very bad." The materials made the containers are not strong enough to hole the salt. When my siter pours the salt in the containers expanded. The lid cannot cover the top completely. Therefor, it make the salt become hard, and it cannot absolve. Right after they install the system, the lid did not fit the top of the container so I called the office. They sent to me the lid having the same problem, did not fit it. My sister had to use a plastic to cover the top of the container and put the lid on the top to prevent rain or dust get inside. A few weeks ago, the man from the company came to do maintenance, he had to use the water hose to melt down the salt so he can clean it. The salt was from the date they installed the system; it went down, and my sister just add a small bag of salt about 6 months before the man came for maintenance. After the man clean up, he put the new salt in. After he finished it, my sister use marker the mark the level of salt. After 3 or 4 weeks, my sister check the salt container to see how much salt inside. It was the same level when the man pour the salt in. Yesterday, I called the office and ask them if the man can come and fix it because it seems to me that the salt was not use for either clean up the machine or purify the water, and it just stuck together and very hard to break it. The lady told me because we put a lot of salt in. For this new system, my sister pour only one small pack of salt; that all she did. The lady also blamed on the hot weather in Florida. If they have a business in Florida installing water system, then they must know the hot, rain, and humid weather as well. She did not accept the worse material making the containers, but blame somebody and something else. It is nonsense. She told me the manager will call and talk to me, but after a day, no phone call at all. The salt was not use, so the water is not clean and safe to use. I need to buy "Drinking Water Testing Kit to check the water. If the water we use is not safe, the next step will be follow up. I want everyone know about this issue of Eco Water Company . I will give Costco the review as well because I know this company through Costco advertising its in stores and magazine. i don't have any problems with Costco, and I am its members about 15 years with no complain! However, the company of its partnership is very bad. I tried to upload the picture, but it did not work.
