QMP502-3/8 is a 3/8” Compression Diverter Valve that connects to your kitchen faucet.
This diverter valve allows you to switch between the tap water from
your faucet and filtered water from the unit. The tubing attaches
snuggly to the compression connection and diverts the water to the
filtration unit when you pull the pin out. Simply push the pin back in
to return to regular tap water.
