ZRO-4 Undercounter 4 Stage Zero Waste RO Water Filter

We''ve had this system for over a year now. Water quality and operation is fine, but it is very difficult to install and maintain and comes with poor instructions. Maintenance parts are expensive, and do not include everything you need to carry out the maintenance procedures.

We had to get a handyman to install this system and it took him several hours to put it together. Then we realized that the system requires power and has to be plugged in to operate. Unfortunately, our home, like most homes, did not have electrical outlets under the kitchen sink. So we had to call an electrician to install an electrical outlet for the unit to be plugged in. By the time we were done, we had spent more on the handyman and the electrician than what we paid for the system!

Maintenance is also hard. The system require filters to be changed every six months. The replacements kitts and shipping charges from the Watts'' website are expensive. I would tolerate that if the replacement procedure was easy enough. Unfortunately, it''s quite frustrating. The system has several parts and connections. The instructions in the accompanying manual are difficult to follow. In this day and age, you would think Watts could post a video on their website? The biggest problem is that the filter housings get so tight that you cannot unscrew them with your hands to replace the filter. You need to purchase a special wrench, which Watts does not bother including in the filter change kit. You have to order it separately and pay even more in shipping charges.

I have been using this for several years. It works great. Previously I had a wasteful RO system. It trickled water down the drain 24-7. Big waste of water and noise enough to bother me sleeping. This produces about 2.5 gallons a day, which could be plenty or not enough. This one has a small electric pump, which hums when its making water, quiet when it''s done. The water is perfect.
