You mention two power supplies and an 8 pin relay. What is the part# of the relay, and what are the power supply voltages? I assume the solenoid valves are 120 volts AC.

110v to 12v. JQX-13F. Solenoid is 12v. Im using a step down to make it 5v. User reviews were stating it got too hot under 12v and 5v works fine.

I still have yet to get this working.

The 2-wire floats, are they Normally Open?

they can be either/or. by default they are NC.

PM sent with labeled drawing and terminals to wire.

When the Low Float rises, CR1 turns on to indicate Not Low. On the 5V section, the circuit is activated if the NC contact of CR1 is true (Not-Not Low, which means Low) and the High Float is Not High (needs to be NC) then the solenoid is powered along with CR2. The Low is sealed in by the CR2 contact so that when the tank starts to fill and the Low Float causes CR1 to change state, the valve stays open. Once the High Float activates, it opens the circuit, closing the valve and removing the CR2 latch.
