Rinnai's new 107000450 Dedicated Recirculation valve DRV

This is a game changer when your piping in a dedicated circulation line into a Rinnai tankless heater.
By having the tee and check valve built into the cold water inlet will save you time and money.
The union half that is made onto the valve on both sides will be good when and if you have to remove it.
