Test Water to Evaluate the Need for RO Membrane Replacement

It is very difficult to guess when the membrane on a reverse osmosis drinking water unit needs to be replaced. In most cases the membrane has a much longer life span than the other reverse osmosis units filters. Since the membrane is the most expensive replacement component on the unit it makes little sense to replace it before it is necessary.

So to evaluate the performance of your reverse osmosis membrane, Environmental Safety Products (ESP) offers free water sample testing. The process is easy. Simply contact us by email or phone to request a membrane performance test kit. The kit will be mailed postage pre-paid. It will include two small (labeled) sample bottles, sampling instructions and a return address envelope.

Here is the sampling process:

Bottle #1

1. Allow the reverse osmosis faucet to run for approximately 30 seconds.
2. Fill the plastic water sample bottle Labeled #1, making sure to leave approximately ½” of space between the water level and the top of the bottle or cap.
3. Tighten lid to ensure the water sample bottle is well sealed.
4. Fill out the information card sheet that is provided.
5. Place the water sample AND the information sheet into the return package.

Bottle #2

1. Allow the water faucet at your kitchen sink (the unfiltered water) to run for approximately thirty seconds.
2. Fill the plastic water sample bottle marked #2, making sure to leave approximately ½” of space between the water level and the top of the bottle or cap.
3. Tighten the lid to ensure the water sample bottle is well sealed.
4. Place the water sample in the package with the bottle marked #1 (reverse osmosis water sample).
   

Using the return address label provided place the correct amount of postage on the package, and mail it back to ESP. Make sure you include your name, email address, and/or phone number in the package.

Upon receipt ESP will test both samples with a Conductivity Meter. Used to measure product water quality in de-ionization & reverse osmosis system, this electronic instrument measures the electrical conductance of a stream of water. Comparing the conductivity of your treated water to the conductivity of your untreated water tells us the percentage of contaminate rejection being performed by your reverse osmosis system. This percentage tells us how well the membrane is working. Once we have the test results, we will contact you by email phone, or mail with the results. You can typically expect to hear from us 5-7 days after you mail the samples until.
