Great value in a brand-name, performance-validated RO system!

Reverse osmosis, also known as nano or ultra-filtration, is the finest home water treatment system available, capable or removing particles as small as 1/1000 of a micron. The Pentek RO-2550 is manufactured by U.S. based Pentair Water, the largest manufacturer of water treatment products in the world. It has been third-party tested and certified by NSF International against NSF/ANSI Standard 58 for the reduction of Barium, Cadmium, Chromium (Hexavalent and Trivalent), Copper, Cysts, Fluoride, Lead, Radium 226/228, Selenium, Turbidity, and Total Dissolved Solids (TDS). Like most reverse osmosis systems, it can also be expected to significantly reduce a wide range of other contaminants as well.

The Pentek RO-2550 reverse osmosis system offers high quality drinking water at a fraction of the cost of bottled water and without the hassle of re-filling bottles. Bottled-water quality drinking water will be right at your fingertips anytime you need it, for drinking, cooking, and more. Its compact size makes it a great choice for use in homes, cottages, recreational properties, and even RVs! The RO-2440 can be easily connected to your fridge ice-maker and water dispenser.

Size: 13 1/2" wide x 5 1/2" deep x 17 1/4" high; 17.3 lbs
Storage Tank: 2.8 gallon max. capacity depending on water pressure
Approx. Size: (diameter: 9 inches; height: 13.5 inches)
Output / Production: Testing by NSF International according to NSF/ANSI Standard 58 yielded 15.04 gallons per day with source water test parameters of 50 PSI pressure input, water temperature of 77F, pH of 7.5 +/- 0.5, and 750 ppm total dissolved solids (TDS). Higher production rates are expected with lower TDS levels. Lower production rates can be expected at colder incoming water temperatures.
Self-Cleaning: The RO-2550 system uses a process of crossflow to constantly clean the membrane to prevent pre-mature fouling and clogging.

This system is designed for use on all chlorinated and non-chlorinated potable water supplies. It is an excellent choice for most homes. If you do not receive your water from a municipal water system (you get your water from a well, lake or other non-treated source), you should have your water tested to ensure it is biologically safe (free of bacteria, viruses, and other harmful microorganisms) before using a reverse osmosis filter as your only water treatment. If your water is biologically contaminated, you should consider a point-of-use or whole-house ultraviolet purifier in addition to your reverse osmosis unit to kill any remaining microorganisms.

Pentek RO-2550 Reverse Osmosis System Installation

The filtration unit and storage tank mount under your sink, out of sight. Water supply is gained by attaching a simple adapter to your cold water supply pipe (copper or plastic). You will have to drill a hole in your countertop or sink frame to attach the attractive long-reach faucet. It is a relatively easy do-it-yourself project, or if you prefer, you can have it installed by a handyman or plumber. The unit includes all installation hardware and a complete installation guide.
