Hi
I was underneath yesterday and all I could find was what appears to be two screws through the side of the tank one near the top and one about six inches down from that, they have wires going to the outside under the head of the screws! Seems pretty basic to me hence my post in case I was missing something else, I’ve removed the tank end cap and cleaned the threaded bit inside but the alarm still sounded. Is there anything else I need or can do !
