Wet Well Housing	Dry Well Housing

Temperature sensors slide into either a "dry" well or "wet" well housing. As explained below the "wet" well housing is no longer available. But we have sourced a "dry" well housing that a "wet" well sensor will insert to.

How to tell if you have "wetwell" or "drywell" Temp Sensor

WetDrywellCompare

Drywell sensors are 5/16" in diameter. This is the most common sensor used by Gatsby. Wetwell sensors are 3/8" in diameter and is less common.

On the LEFT see an older "wet well" sensor and housing. You can see the tip end of the sensor and usually can touch it. Water actually touches the sensor so its always stainless steel. This housing is no longer available. The replacement is a drywell housing that will accommodate the larger diameter sensor. (black)

On the RIGHT is a "dry well" sensor and housing. You might be able to see the sensor but its in the housing. So the water flows around the sensor but never touches. The sensor can be black plastic or stainless steel. Replacement housing is White.
