We frequently get questions about increasing the GPD capacity of the reverse osmosis membrane on RO systems.  This will not only increase the daily production capacity, but more importantly, it will increase the speed at which the RO water is produced.  This allows for better assurance that there is adequate water available when desired, even during heavy use times of the day.  It is also important to have adequate flow available for the ice maker when it calls for water.  A starved ice maker can burn out.  Be sure to read more about Flow Restrictors.
 

This is the same basic procedure for updating a "proprietary" RO membrane to a standard size and style of membrane.  Many owners of "proprietary" style RO systems  convert their systems to use the standard size and configuration that will be less expensive and easier to find.

The membrane upgrade is very simple on most reverse osmosis systems.   Simply replace the membrane with the desired capacity and the correctly sized matching flow restrictor.  These must be matched to keep the proper balance between waste water and pure water.  Mis-matching can either cause excessive waste to the drain or premature membrane fouling. 

This is also a great conversion if your reverse osmosis system has a non-standard size membrane and housing.  In this case, simply replace your housing with the standard size one shown below.  This works on all systems other than those that use a "manifold' system.  A manifold system is one that makes the connections in the plastic head without using tubing  to connect the separate components.   Manifold systems must use the original size membrane.

TDS Meter - Test For Total Dissolved Solids In Water - Reverse Osmosis Membrane Tester - TDS Meter

TDS Meter - Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS - Total Dissolved Solids. A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water - Replace Membrane If Less Than 80% of TDS Is Being Removed - Total dissolved solids (TDS) are the total weight of all solids (minerals, salts or metals) that are dissolved in a given volume of water expressed in milligrams per liter (mg/L), or in parts per million (PPM). The lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. 17 PPM of TDS = 1 grain of hardness. Highly efficient and accurate due to its advanced microprocessor technology. Hold Function: saves measurements for convenient reading and recording. Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries. Measurement Range: 0-9990ppm. From 0-999ppm, the resolution is in increments of 1ppm. From 1,000 to 9,990ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image. Display: large and easy-to-read LCD screen. Factory Calibrated: recalibration is not necessary, but can be done easily with a watch screwdriver. There's no need for messy solutions to initially calibrate the meter. Range: 0 - 9990ppm (mg/L) Accuracy: +/- 2% ATC: Built-in sensor for Automatic Temperature Compensation of 1 to 50 degrees Celsius (33 to 122 degrees Fahrenheit) Power source: 2 x 1.5V button cell batteries (included) Battery life: over 1,000 hours of continuous use Dimensions: 14 x 2.3 x 1.5cm (5.5 x .9 x .55 inches) Weight: 32g (1.13 oz) Simple to use for Reverse Osmosis membrane monitoring. Measure the incoming water and the RO water. Divide the larger number into the smaller number and subtract that decimal from 1. The resulting decimal is the percent of TDS that the membrane is removing. We really like this tester and think that anyone who wants to know about the quality of their water should have one of these TDS Meter Testers.

TDS Meter Inline Tester- Dual Mode Reading - Easily Installs Inline - Very Simple To Use

TDS Meter - Dual Mode - Installs Inline - Check the TDS level with the push of a button. Now you can easily check to make sure the water from your reverse osmosis system is top quality. Measure the tap water coming in vs. the purified water going out of your system at any time. Very easy installation. Simply cut the line out from the RO membrane housing and install the inline probe between the membrane housing and the shutoff valve, when possible. The closer to the membrane housing the better. Insert the ends of the tube into the John Guest quick connectors on the TDS meter probe. Then cut the inlet feed water line to the system and install the other T/probe. FEATURES Displays TDS levels of the feed water and product water with in & out electrode probes. Highly efficient and accurate due to its advanced microprocessor technology. Auto-Off function conserves battery power. The unit shuts off automatically after 10 minutes of non-use. Dual Range 0-9990 ppm (From 0 - 999 ppm the resolution is 1 ppm. From 1000 to 9990 ppm, the resolution is 10 ppm, indicated by a blinking 'x10' image.) Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver. Comes equipped with John Guest Quick-Connect T-fittings as shown. Installs quickly and easily. SPECIFICATIONS Range: 0-9990 ppm Accuracy: ±2% Cable Length: 24.5" (including sensor) Power source: 2 x 1.5V button cell batteries (included) Battery life: over 1000 hours of continuous use Size: 7.6 x 2 x 4.7 cm (3 x .8 x 1.9 in.) Weight: 79.4 g (2.8 oz.) Always know if your RO membrane is performing correctly!

Leak Controller for Reverse Osmosis Systems, Water Coolers, Refrigerators, Ice Makers and Coffee Machines.

Save a flood inside the house. Prevent costly water damage. Automatically shut off the water to leaking Reverse Osmosis Systems, Water Coolers, Refrigerators, Ice Makers and Coffee Machines. Alarm flashes and beeps to notify you to the system shut down. Very simple to install and use. Brilliant design. Simply place the sensor (Similar in size to a small computer mouse) where water will collect below the system. Cut the incoming 1/4" water tube and insert each end into the easy to use John Guest quick connectors on the controller. When the sensor gets wet it shuts off the incoming water at the controller. Reset the sensor by wiping it dry. It even comes with a built in filter change reminder. Set it to beep and flash after 6, 12 or 18 months, when it is time for a filter change or scheduled maintenance. # LCS14 with 4 1/2' cord that connects the sensor. The Leak Controller is a great way to control costly leaks.
