kind of a free bump for more opinions and with some info too
okay lots of reading. i thought the float switch i had just had a metal ball that hit 2 contacts shorting them out to get the pump to run. i found out it uses a ball to close a physical switch which can stick, and i guess mine has. the west marine one i have is rebranded, but what dont they rebrand.
i found 6 reviews on the water witch, one said it worked fine for 6 months then died, the other 5 all said it works great. i did find one review where the only failure was a guy had his RO pump line failed and could not sense ultra pure water but it worked fine on normal water. i guess i will give it a try.
i also found out some complaints about the sensor type some say oil will foul them but less in the inductive type like the water witch. it is more for the other electronic type. now i know how the induction type works, and even if it gets oil on it, it only needs a very small surface clean to work
normal disclaimer no connection to anything etc etc
