Here are a bunch of pics. All taken while the tub was running. I didn't turn it on. It was just running cause it seems like it always is.lol. when I turned the Jets off, the green light stayed lit and the red light went out. Also the small black sensor in the heater tube had a drip of cold water coming off it and some staining on the heater tube below it so I assume small leak there. As the weather has gotten cooler, it has been running non stop.
