Your asking for trouble, sooner or later something is going to fail on you and your either going to loose l/s or have one big mess on your hands. Its happen to all of us, some more than once!! Im going to be buying Reeferrobs top off next week. Water goes down an inch and it fills it backup an inch, pump shuts off. Im going to program my R/K to only power the pump 1-2 minutes, just incase there is some sort of problem when Im not around. Just an extra safety precaution.
where am i asking for trouble? What part is wrong to you?
my plan hopefully soon is going to be.
Use DA's Float switch kit that attatches to RKL.
Also the built in timmer function to control ATO pump to only have power for a certain amount of time.
Get a sprinkler solenoid ( i saw someone use one) inline with my ATO to control open and close of the drain into the ATO tank.
Use float switch to control solenoid.
Put Solenoid on a timer to control when the solenoid has power.
