This company came to change our reverse osmosis filters as they took over from our previous company. The guy arrived on time and was very nice. He was very fast at changing the filters. We gave him a tip. Our water tasted fine for about a week. Now it tastes like someone came in during the night and removed our new filters replacing them with 5 year old filters. I don’t drink sodas or juice. Filtered water is my beverage of choice. This water now tastes so bad that I will probably buy the reverse osmosis system from Costco when my budget permits. I would have bought their system already, but I didn’t want to impose on my brother-in-law to show me how to install it. Live and learn. They might be good for your solar needs, but I won’t use them again for my water.
