DX3 Winterization Tee-Valve Backwards
A simple visual of the Tee-Valve, it looked like it should be installed correctly. However, it was functionally backwards as I determined by blowing air thru each of the ports and observing the exit points.
Details: The Tee-Valve has 3 ports to it with a switch at the tubes intersection point.
Port #1- (Open/Closed) Depends on switch position. Connects to water tank.
Port #2*- (Open/Closed) Depends on switch position. Connects to winterization hose.
Port #3- (Always Open) NOT Dependent on Switch. Connects to water pump.
*(Note: Ports #1 & #2 cannot be open/closed at same time.)
My Port #3 was connected to Water Tank and Port #1 connected to Pump. In this configuration, antifreeze dumped into water tank vs going into pump.
Thought I would document this so factory could check to see if product using is labeled/manufactured wrong or something else is occurring during installation. Initially, thought we had a bad switch, but that was not the case.
