To come straight to the point, TDS value isn’t directly related to water quality.
No. TDS stands for total dissolved solids. The higher the TDS is, the more impurities water contains. But what are impurities on earth? No matter beneficial natural minerals or harmful substances, they are all regarded as impurities in water.
As a result, water quality can’t be determined only by TDS value. It is just one of standards that reflect water condition and you can’t conclude that water with low TDS is definitely of good quality.
TDS has more influence on water taste, not overall water quality.
Waterdrop under counter water filter reduces harmful pollutants while retains natural minerals, thus ensuring purity and good taste of water at the same time.
What is the difference between the WD-TSA system and the WD-TSB system?
The WD-TSA system does not come with a faucet. It will connect to your existing faucet. Meanwhile, the WD-TSB system comes with an additional water faucet.
Can the product filter well water?
No. This system is designed for Municipal Tap Water. If using well water as the source, please make sure the feed water has been through a pre-filtration system, otherwise, large particles in well water will clog the filter easily and shorten filter life. For the solution with a pre-filtration system, please search for WD-PFK.

Questions and Anwsers

What is the distinction between WD-TSA and WD-TSB

WD-TSA directly connects to your original faucet and has different connecting options for your under-sink or an RV. While WD-TSB comes with an extra lead-free brushed stainless-steel faucet. Therefore, compared with WD-TSB, the installation process of WD-TSA is simpler without drilling a hole for the faucet. However, it is the extra faucet that the combination of the dedicated faucet and your original faucet will separate the filtered water from unfiltered water, thereby secures a prime water quality. You can make your choice based on your household needs.

How do I know when to replace my water filter?

The recommended service life of the filter is as follows:
The PP filter has a 6-month lifetime; the GC filter has an 8–12-month lifetime; the CT filter has a 12–18-month lifetime.
Note: The filter's service life is related to the water quality and water usage. If the flow rate is significantly reduced or if the water has a peculiar smell, we suggest that you replace the filter.

How to use the quick-connect of this under-sink Water Filter System?

Please refer to the following ways. Besides, you can get more detailed instructions from the manual on the product page.
To connect: There is an existing mark at the end of the tubing for you to confirm if the tubing is fully inserted into the fitting.
To disconnect: Use your thumb and index finger to press down on the lock sleeve. Use your other hand to pull out the hose from the fitting.
Note: Please do not pull out the tubing directly, or else it will damage the fitting and cause leakage

What to do if water leaks after installation?

Water may leak at the connection position or thread due to the incomplete connection. ​When water leakage occurs, turn off the water supply. If the water leakage is at a thread, please wrap Teflon tape on the external thread. If the water leakage is at the inlet and outlet, please insert the quick-connect fitting to the end.
