TURBS is correct. I put water in my fresh water tank and switched on the pump, opened kitchen faucet, pump came on and followed the sound to my closet in the kitchen cabinate. Found an access panel held in by 2 screws. The pump was also located on the inside of where the inlet is to fill the freshwater tank from the outside. Hope I didn't just confuse you, as it sounds weird the way I explained it.
