There are many different methods of connecting a Reverse Osmosis system to a water source, and one of the most popular ways it’s the Faucet Diverter Valve. It can be installed into the most bathroom and kitchen faucets in minutes without making any permanent modifications and still gives you access to use the tap. In most cases, the threads on faucets are pretty standard, but in some cases they do vary. We do carry an adapter kit, but you can usually adapter fittings at your local hardware store too. Once the Faucet Diverter Valve is installed you can then turn the valve handle to either have water feed your RO system or feed out of the faucet as it would normally.
