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.

Replace every 2,500 gallons or 6 months
- Reduces chlorine, organochlorine compounds, chlorination disinfection byproducts (THMs and HAs), many VOCs and more.

Self-Cleaning: This system uses a process of crossflow to constantly clean the membrane to prevent pre-mature fouling and clogging.
Storage Tank Capacity: 3.2 gallons (12 litres)
Made in: South Korea

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.

* Note: While the system membrane has a manufacturer's capacity rating of 75 gallons per day, this level of production can only be achieved under what would normally be considered to be ideal (and unrealistic) conditions. In real world conditions, actual membrane production will be much lower, generally in the range of 25% to 40% of the manufacturer's membrane rating. However, the manufacturer rating is generally a good method of comparing relative membrane capacity between different RO systems.

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 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.

Nelsen Quick Change Twist & Loc RO System Model #: TWIST-LOC-RO-75 Reviews

Works perfect4 Stars
This RO system works just as expected. It does fill slow. I don't think the listed flow rate is anywhere near accurate. It is not certified which I found out after I ordered it. It installed easily. I would order again if they get it certified. If the fill rate was faster and it was certified I would give this 5 stars. - Dan C
