Septic Tank Pumps....Question About the Float and Float Switch

[Arkapig]

Got a few questions about septic tank effluent pumps...do you run a pump with the built in float and float switch, or do you run a pump without the built in float and float switch?

It seems like most installers put in a separate piggyback float and float switch that turns the pump on/off when the effluent side of the septic tank reaches a certain level instead of putting in an all in one pump with a built in float and float switch.

What are the advantages of running a piggyback float and float switch? TIA.

You don’t want a lot of water at once pumping from the tank to the drain field.

You want the drain field to rest between pump cycles.

Having an off board float will allow more flexibility with setting the pump down level and the cycle volume per pump cycle.

Hardwire floats also allow for control
