Agreed. 100%



If there is a malfunction the difference is a wet floor vs a potential crash from sudden salinity drop. I know of at least 2 or 3 tanks that have had complete crashes this way. Redundancy is insurance, laziness is risk.

Malfunction is highly unlikely if even posible. The solenoids fail in off position and even if one fails the second one will prevent failure. Max on time is set with profilux or timer so even if float fails sump will only fill slightly over float. Profilux also has alarm for this case.

How would such a system fail? More likely one would forget to fill reservoir, pump runs dry and fails, tank crash.

Don't mistake laziness with convenience or progress for that matter.
