As I'm allways looking for simple way I think that if I connect simple 2 wire level sensor parallel to high pressure switch that 2 contacts exist I will have double safety: if pressure switch is NC normally close contact than system is stopped. If level switch is give top level tank is full of clean RO water will give NC also to stop system. Yes will work like this well.
First I was thinking in serial but will not give proper signal contacts NC when activated that both and level switch and high pressure need to be activated to stop working system. Yes wrong - need to be wires parallel connected and whoever first is activate contact will stop RO unit.
