I'm with Craig on this pre-action issue. Why at all, but if the owner insists what advantage do you get from double interlock? Double interlocks are primarily useful for warehouse size freezers where an accidental filling of the pipes is unwanted because the water will freeze. Are we mistakingly calling single interlock with supervisory air a double interlock?
