I am installing a sump pump in my basement and was shopping around for
a sump pump at Lowes when the Watchdog combo pump caught my eye. Seems

I see if one goes bad ,you have to change out the whole unit .Am I
better off putting a seperate primary and backup in the pit?

if your home is above the surrounding grade, a overflow to daylight is
best.

If youur basement has high value I would go seperate pums and seperate
drain lines!
