Here is a picture of the refill switch as it is mounted under our bridge. Note the tab that I left on top to mount the PVC. The wires do not go into the water, as it may seem; they are stapled to the bridge on the other side of the pipe.  Also, note the wing nut.  The sensor, with bracket, was placed inside the PVC pipe with the screw in the slot. With the wing nut loosened, the inside assembly can be slid up or down to set the level of your pond.
