The ProOne Water Level Indicator Tap (also known as Sight Glass Spigot) replaces the original tap supplied with Berkey and Propur ProOne systems. It is a stainless steel tap with a glass water indicator that is encased in protective stainless steel which allows you to see how full the lower chamber of your water filter system is. If you are concerned about overflow of the lower chamber this makes it quick and easy to see the water level. The 2 position tap handle is plastic but the tap body itself is made of food grade stainless steel.


  • Quickly view the reservoir water level of your Berkey or Propur system without removing the upper chamber
  • Replaces the standard tap (spigot)
  • Non-drip
  • Durable glass tube in a stainless steel protective housing
  • Genuine ProOne Accessory
