Existing float
switches on the market mostly use micro switches to actuate a
diaphragm valve which can be problematic depending on the air
quality. MA micro switch has small metal components with very
tight tolerances which are highly susceptible to dirt in the
system. Another major disadvantage is that the metal components
stick or don’t work when there are long intervals (i.e. days)
between operation due to slow water accumulation.
The water
monitor on the other hand has no metal moving components, only
Acetal moving parts with loose tolerances. Some water monitors
are in use in factory sumps which may not need emptying for
months and they still work when called upon. The best
installation is to fix the float switch where the water is and
place the pump out of harm’s way. The float switch is much less
expensive than a pump. The mounting holes on the float switch
have been designed for 2” flat bar to go between the webs using
¼” bolts.
