Flowlok Leak Detection

FREE BONUS: Flowlok Leak Protector

The FLOWLOK Leak Detector is an innovative device that installs right below your water filtration system in minutes. No special tools are required and it does not need electricity to operate. FLOWLOK Leak Detectors utilize a highly compressed safety disc that expands when it absorbs water. Once the safety disc has detected water it expands and trips the FLOWLOK safety lever to shut off the water entering the water filtration device. Safety discs are replaceable and are economical.

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.
