Worst RO in the market. Upon installation the pump switch was deliberately shorted by the installation guy resulting in pump failure after a few months. I made a complaint and it was not resolved. If you are buying this product, be ready to shell 15000-20000 per year on parts and filters.
Bought Kent grand plus for around 18000 a year ago, spent additional 12000 on filters so far and it has only been a year. The RO is useless now as it needs a pump replacement because the installation guy had shorted the pump switch so that he could come back and get more money out of me.
Finally decided to throw this piece of garbage out of the window and install Aquaguard instead.
