Which is the best float switch?
Horizontal float switches are perfect when the access to the top and bottom of a tank is limited. They are used when applications are mounted through the side of a tank with a hinged float attached to a fixed housing unit, where the horizontal float switch rises and falls with the level of the liquid.

How long do septic float switches last?
In relatively clean water and with infrequent cycling, float switches can last many years (5–10 years is not uncommon for a good float). In harsh industrial wastewater, their life might be shorter – you might get a couple of years if lucky, especially if maintenance is overlooked.Sep 9, 2025
