Great product

This was just what was needed to add the extra comfort level when out on the water. The installation was easy and the only thing I would change would be to have longer wires.

I have a rule 800 non automatic pump..can I add this switch to my existing pump to make it automatic?...will I still be able to hit the switch on the panel to run it manually?...thanks?
Yes, you can add a float switch to this pump to make it automatic. We offer 3 different float switches, P/N 35A, 37A and 40A Yes, but the wiring will need to be changed. The wiring diagram is at:
