PROBLEM TO BE SOLVED: To provide a water supply control device capable of detecting a liquid level in a pipe more correctly. SOLUTION: The water supply control device includes a first liquid level detection electrode 7 mounted to a first liquid pipe 21a stored in combustion equipment 1, a second liquid level detection electrode 6 mounted to a second liquid pipe 21b arranged in the combustion equipment 1, a burner 24 for heating the inside of the combustion equipment 1, a water supply pump 8 for supplying water to the combustion equipment 1, and a control part 9 for controlling the start/stop of the water supply pump 8. The first liquid pipe 21a is arranged in a high heat receiving area in the combustion equipment 1. An outer peripheral surface of the second liquid pipe 21b has an external outer peripheral surface 21b1 arranged outside the combustion equipment 1 and an internal outer peripheral surface 21b2 arranged inside the combustion equipment 1. The internal outer peripheral surface 21b2 is arranged in a low heat receiving area where an amount of received heat is smaller than in the high heat receiving area. The control part 9 controls the water supply pump 8 based on a liquid level of the first liquid pipe 21a detected by the first liquid level detection electrode 7 and a liquid level of the second liquid pipe 21b detected by the second liquid level detection electrode 6.
