A liquid chemical delivery system (20) has a pump (27) driven by an electric motor (28) to draw a liquid from a bottle (21) and dispenses the liquid into a septic system (12). Separate independent controls (36,37) connect the electric motor (28) with a source of electric power (34). One of the controls (253) has a wireless remote switch (273) operable to trigger an electronic control unit (268) to activate the electric motor (228) that drives the pump (227) to deliver liquid to the septic system (212). |
