4 Way Wet Diverter for Aquaponics or Hydroponics

This is a Diverter or Indexing head for Hydroponics or Aquaponics. This is a wet and low pressure diverter designed for 1" PVC pipe fixtures.

I'll be using a 1" high flow pump for my setup, so I'll have two overflows which feed beds along with an emergency overflow in case the system backs up.
