* Position "Open" to allow the water flow in/out the water tank

* Ball Valve For RO Water Storage Pressure Tank

* Note: Standard RO system connection is 1/4" throughout, including all connectors and valves. If you ever made modifications to system to make it 3/8" or 1/2", then you will need the 3/8" or 1/2" ball valve. Hope this clarifies some confusion.

 

 

* We carry different fittings in variation of sizes: 1/4", 3/8", or 1/2" adapters, connectors, fittings, or valves.  Most are not listed online, to avoid confusion to majority of RO system customers.  

* Send us a message with specification, intended application, and image of your setup or old fitting  to check if we have what you need.
