Best Overall: PUMPSPY Tank Low Level Switch

We are personally inclined towards pumpspy tank low level switch, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. This universal replacement float switch will automatically activate your water pump. It works really well once the float is nearly all the way up or all the way down. This switch has a "pass-through" socket that plugs into the outlet and the pump then plugs into this. It can be short to long, deep or shallow.

This float has about 8 inches of travel between "off" and "on",the down or off position is about 5 inches below horizontal and the up or on position is about 3 inches above horizontal.

It can operate either way and it is easy to wire in, highly recommended. It can be used for an in-let flow of water and out-let flow of water from the tank to control the level of water, and it works in both ways.

This switch can be wired in both configurations. It works well as a dry pump warning system. The float will work with anything that needs a float for normally open or normally closed contacts.

The turn on range is 8+" and the turn off range is. It is automatic, if in about 1/2 inch of water or more it kicks the pump on. The pump must be fully submerged when operating in order to cool itself.
