What is TDS Creep & How To Fix It 

WaterFilterGuru.com

If you’re getting a high TDS reading from your reverse osmosis system, you might be dealing with an issue known as TDS creep.

In this guide, we’ve defined TDS creep, discussed why it happens, and whether you should be concerned about this temporary TDS elevation. We’ve also shared some of our top tips for fixing the issue.

TDS creep is a term that describes what happens when a reverse osmosis system isn’t used for a short period, causing the pressure in the semi-permeable membrane to equalize and balancing the TDS levels.

What Causes TDS Creep?

The most common cause of TDS creep is if your reverse osmosis system has short-duration, frequent cycles of water treatment.

Yes, TDS creep affects the TDS reading of reverse osmosis tap water. In fact, a randomly higher TDS reading, which decreases to a lower reading as you continue to dispense water from your RO unit, is the most obvious sign of TDS creep.

Does TDS Creep Affect Water’s TDS Reading?

No, TDS creep isn’t something to be concerned about. It doesn’t mean that your reverse osmosis membrane needs replacing or that your RO system is about to break down.

Should You Be Concerned About TDS Creep?

Discard Your First 1-2 Glasses Of Water If you use an RO filter system without a tank, fixing TDS creep is easy: just fill 1-2 glasses of water and discard these initial water batches.

How To Fix TDS Creep

Once the RO system kicks in and fresh tap water starts flowing through the filter stages, the TDS creep issue should no longer be present.
