Use a small amount of plumber’s tape to secure the gasket if needed, but be careful not to place too much of it, as this can cause your faucet filter to not function correctly.

Rotate the connector to tap: Rotating the connector to tap is one of the most critical steps in installing a faucet water filter. To do this, locate the nut that connects the filter to the faucet and remove it by unscrewing it with a wrench.

This prevents water from splashing out of the faucet while installing other parts. Once everything else is installed and ready for use, carefully remove your hands from the faucet.
