I have a levelor automatic water fill (see picture). The sensor is installed in the skimmer (as shown in picture). The problem is that the sensor only lasts about 2 years; I've replaced it two times in 4 years! Now it's gone bad again. It's a real pain to replace because it has to be fished entirely through the conduit (which has a lot of twists and turns). I'm told the sensor can't be spliced in... it has to be completely rewired. Has anyone else had a problem with these sensors? Is there another sensor unit worth replacing to get more years out of this sensor... The Levelor unit itself and the solenoid turn-on/off have worked fine, though. Any advice is greatly appreciated.
