1. There are 3 different level sensors used by HWH. Yours is 11 years old.
2. The older is the silver mercury filled sensor
3. The one between the Silver and the current is a black sealed box about the size of a cigarette pack
4. The current is located in the Plexiglas cover at the HWH pump assbly. I am not positive when they went to the Plexiglass outside control assbly mounted on the pump assbly. But, it is easy to figure out. Go to the HWH pump and if you do NOT see the control mounted to it with a clear plexiglass cover you have the older system. The 2 older systems use 3 spring mounted screws to hold and adjust the sensor. The Plexiglass control has the sensor mounted inside that control box and is adjusted at the Plexiglas area on the side. No screws on this one. Doug
