Installation Steps
NOTE:
•The RO system must be connected to the COLD water supply ONLY.

place where it may be damaged.
•Do not install the system near any heat source.
•Do not install the system outdoors.
How to Drill a Hole on Your Sink or Countertop (Optional)
NOTE: Please confirm if there is an existing hole available to install the RO faucet. If not,
please drill a hole in accordance with the following steps.
It’s highly recommended to watch the YouTube video “How to Drill Faucet Holes” for better
understanding of the process. There is also a sticker for your reference to drill the hole.
Remember to wear safety glasses to protect your eyes while drilling the faucet hole.
1. Choose a diamond core bit for granite, and a carbide drill bit for stainless steel. Do not
use a hammer drill on nature stone, glass or ceramic;
2. Glue the sticker on your sink or countertop, and drill a hole referring to the sticker hole
size (1.38”);
3. Make an indent with a center punch on stainless steel sink before drilling to help guide
the bit;
4. Be careful when drilling on a porcelain sink, as it can be easily chipped. Apply downward
pressure firmly on the bit until breaking through the surface;
5. Starting at lowest speed, hold the drill straight with firm pressure to prevent the bit from
walking on the counter;
6. Once breaking through the surface, swirl the drill a little to apply pressure in a circle
evenly.
Prior to installation, it is highly recommended to watch the video “Waterdrop RO Installation”
on YouTube.
