Frequently Asked Questions

Q: Why does the filtered water taste weird?A: The filter is not installed appropriately, or it should be replaced. Please re-install it in a correct way. If there is still bad taste, please replace the filter.

Q: Why does the TDS value not lower after filtration?A: TDS stands for total dissolved solids. It is composed of inorganic salts and asmall amount of organic matter. This system cannot lower the TDS value because it removes harmful substances while keeping beneficial trace elements, which can increase the TDS value.

Q: Why does water leak between the mounting base and the faucet?A: Remove the filtration system from the faucet and check on whether the O ring at the connection is placed correctly. Ensure that the thread between the faucet and the filtration system is screwed in firmly so that the O-ring can work.

Q: Why is the water leaking or dripping?A: Check on whether the selected adapter is correct, or weather the adapter sealing ring and the base sealing ring are installed firmly. Check on whether the spout (D) and the stainless-steel base (C) are installed in place. Flush the filter for 3-5 minutes to activate it, and then there will not be water leaking or dripping.
