Hijacking an old thread here... did placing the mechanical float valve separate from the optical sensor for the Tunze 3155 do the trick for you?If that’s the case then it comes with an extra mount . I’ll turn the alarm back on and move that safety switch up higher then my water level will be when return pump is off! Thanks guys and gals
I just installed and the alarm keeps triggering. Watched a BRS video that said to raise the optical sensor to its highest position, but this no longer seems logical as it would mean the float switch is more likely to trigger the alarm.
Thanks
