A timer to shut the ato off after a couple minutes if it gets stuck on.
Yep!
Digital ($15-30)is best, because you can set increments to the precise amount of time your pump would take given a max fill, but analog (often less than $3) is fine for a temporary solution if you are building it out under a budget.
Ato is one of those procedures that i would love to automate, but it insures that i spend at least a minimum amount of time to look at the sump and a number of other things that i might otherwise neglect.
