Kind notice:
Please refer to this diagram and be informed that you need to drill a hole on your countertop to place the smart faucet (No need for this step if your countertop already has a hole). Besides, an adapter will be installed on your household water tubing to connect to RO system’s wastewater tubing and input water tubing.
Electricity is required to run the RO system.
We do not recommend using well water as source for our RO systems. We do not recommend connecting tankless RO to a refrigerator or ice maker.
Installing the system with any parts or accessories that are not provided by Waterdrop may cause the system to malfunction or shorten the lifetime of the system/filters.
