The RS-094-MK6 kit includes the standard RS-094 valve (3/4-inch) and water receiver and sensor, plus a step-down transformer (120, 208 or 240 VAC to 24 VAC) and plenum-rated wires to the sensor and transformer.
Ideal for tanks located in the space between the structural ceiling and the dropped ceiling, where the scale of the damage from an undetected leak can be even greater.
