QMP520MM-3/8 is a 3/8” & 1/4” Compression Diverter Valve Return that connects to your kitchen faucet.

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. The two unique features of this unit are the
return feature which prevents the filtered water from getting mixed with
tap water and it is specially designed to be anti-drip.
