A liquid dispenser (10) is provided for dispensing a desired amount of liquid from a bottle (12), without leakage or dripping. The bottle (12) is mounted in a fixture (14) attached to a wall. The bottle includes an inlet (28) and an outlet (30), with one-way valves (36, 60) operatively sealed in the inlet (28) and outlet ports (30). A foam-filled foot pump (40) is operatively connected to the inlet valve (60) for the inlet port (28), such that air may be pumped into the bottle (12) to pressurize the contents thereof. Upon pressurization, the liquid is forced through the outlet valve (36) in the outlet port (30). An air filter (54) is provided for the pump (40), so as to preclude contamination of liquid in the bottle (12). Excess pressure is released through a relief valve (56) to preclude over-dosing of liquid from the bottle (12).
