  2. Installing a RO Drinking Water Faucet

    WECO RO Drinking Waer Faucet with Pull Down Kitchen Faucet

    Most of our under sink reverse osmosis (RO) water filtration systems come standard with an European style long reach goosneck drinking water faucet. The minimum hole required on the sink or countertop is 7/16"in diameter. However, the included faucet will fit in holes up to 1 ¼" in diameter.

    If the sink has a spare pre-drilled hole you may use it or drill a ½" hole for the faucet in a location convenient for dispensing filtered water and where the faucet stem is accesible from below the sink. Soap dispenser or spray hose holes can be used for the faucet as well.

    Alternatively, you can replace your regular kitchen faucet with a luxury triple faucet that lets you connect hot water, cold water and RO filtered water lines.

    Whole House RO Checklist


    What is whole house reverse osmosis?


    Reverse osmosis or RO, as it is commonly referred to, is the process of purifying water with the use of a permeable membrane to remove unwanted substances from the water.  These substances range from contaminants, chemicals, minerals, and impurities.  This process is used to turn poor quality water into

    Microplastics in Water

    Dan Jackson

    What are Microplastics?

    Microplastics are considered plastic particles 5mm (5000 microns) in size or less.  Plastic particles are in wide use in industries such as cosmetics, ion-exchangers in some water filtration systems, air blasting technology, tires, etc.  Microplastics are divided into two classes:  Primary microplastics are in their original form, and secondary microplastics are smaller pieces derived from breakdown of primary microplastics.  Microplastics have a very long degradation process that contributes to buildup in the environment.


    Are there health concerns with Microplastics?

    Substances Reverse Osmosis Technology Struggles to Remove

    Nidia K Trejo

    What RO Doesen't Remove

    Reverse osmosis (RO) was first commercialized at UCLA in the 1960s. Now it is used throughout the world at the advanced, end stages of water treatment. The quality of water output from these RO systems is high. This makes the water safe enough for people to drink and can be pure enough for use in industrial processes.

    RO effectively removes dissolved salts that can contribute to water hardness as well as metal ions like lead and mercury. The pore size of RO filters enable proper removal of protozoa, bacteria, and viruses from water. The pores are an order of magnitude smaller than nanofilters and three

  10. Guide for "Salt-Free" Water Softening

    Salt-free softening guide

    Water hardness is measured by the amount of calcium and magnesium minerals in water. Within the water quality improvement industry, Grains per gallon (gpg) is the most common method for designating the water hardness. Lab reports may express hardness using parts per million (ppm) or milligrams per liter (mg/L). Multiply the grains per gallon by 17.1 to get the equavalent ppm or milligrams per liter.

    The Water Quality Association breaks down water hardness into the following categories:

    • Soft:   < 1 gpg   (<17.1 mg/L)

    • Slightly hard: 1 to 3.5 gpg (17.1 to 60 mg/L)

    • Moderately hard: 3.5 to 7.0
