I bought a water softener and reverse osmosis system at the Newmarket water depot four years ago, which they installed. Only one year later, when I went back to buy a new filter, the woman behind the counter not only told me they no longer carried the filters, and that I would have to come back and speak to a manager. Instead, I called Aqua Bon in Aurora, who came out and replaced the filters. The Aqua Bon tech also pointed out the under-sized plastic hosing installed by the Water Depot people. I've called Aqua Bon every year ever since. Just today, when re-organizing my basement, I noticed the same Water Depot plastic hose connected from my laundry tub tap running directly into a drain -- with hot water running from the tap to a drain, constantly. It had been installed by the Water Depot people. Apparently, I've been heating and draining hot water for four years, and didn't even know it. I would not recommend anybody go to Water Depot for softeners / RO systems.
