One of the most ambitious at-home water filtration systems on the market, the Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System eliminates a laundry list of impurities from drinking water, including sediment, chlorine, cysts, lead, and a number of total dissolved solids, or TDS’es, which are greater in some municipalities than others (including nitrates, chrome, arsenic, turbidity, perchlorate, and more). However, it is important to note that unlike some smaller units, this particular filtering system does not remove bacteria and viruses. As such, it is less effective for those concerned with disease, but works very well in all other areas of taste, purity, and chemical balance (including gardeners).
As a reverse osmosis system, the Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System is one of few on the market that can eliminate pharmaceutical remnants from the water. In addition to the reverse osmosis process, this system runs three different filters before RO and one after RO to ensure purity.
Users report being very pleased with the high quality of water that is produced by this product, with no taste, odor, or visual impurity. In addition, the installation is straightforward and the manual is sufficiently detailed. Most owners report installation taking no more than an hour or two for the unit to be fully functional.
One consistent complaint is that the unit is noisy, emitting a loud hissing sound that is distracting to homeowners who install this product in their kitchen. Because the 5-stage filtering process takes a bit of time, he Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System contains a 3-gallon storage tank of readily available water. Whenever water is drawn from that tank, the purifier will kick on to replace it, and this is when the hissing sound is present.
The other complaint is that of high water usage. All reverse osmosis water purifiers require several times more water than they actually produce; some users have reported up to 12 gallons of waste water per 1 gallon of pure water during certain seasons in areas known for very low water quality. To address this issue, the manufacturer does provide additional equipment that can improve efficiency and reduce waste water. This equipment is sold separately.
Bottom line: The Watts WP5-50 Premier Five-Stage Manifold Reverse Osmosis Water Treatment System is a thorough at-home filtration system. It serves its intended purpose very well: in terms of water quality (including taste, odor, and appearance) this product is one of the best. However, home users complain of a loud hissing noise, and the unit does create quite a bit of waste water for the amount of purified water it produces.
