The high-water alarm activates if the effluent level in the pump tank rises too high. This can be a result of the failure of the pump to come on, or because it is on, but is not successfully pumping the effluent out to the disposal field. There are several steps that you can try to remedy the problem. First, make sure that the pump is plugged in. Second, make sure the breaker is “on.” Next, plug the pump directly in to a power outlet (usually, the pump plugs into the float switch, which plugs into the electric outlet). If the alarm goes off, then the problem is with the float switch. DO NOT leave the pump plugged directly in as this can cause the pump to burn up! Call our office for recommendations for a contractor to make repairs. Depending on the type of OSSF, you may be able to alternate the disposal field.
