I couldn’t figure out what I found attached to this water heater yesterday. The pictures aren’t very good, but the drain valve on the water heater was connected to a pipe that has a pressure valve and an Intermatic timer (like you find on a pool pump motor). The pipe then disappeared into the wall. Any ideas on what that would be?
I also added a last pic of the pex line that was attached on top and the water line for the icemaker to the garage fridge.
