The apparatus and related method employ fluid pressure to first separate the water accumulation chamber from the filtration chamber of a filter assembly by closing fluid flow pathways that allow water to flow into the accumulation chamber. With the chambers separated, fluid pressure is applied to the accumulation chamber to open a drain valve and push water out of the accumulation chamber. The period for which pressure is applied to the accumulation chamber can be regulated by sensors detecting a low water level, or can be timed, or both. When the water removal is completed, the fluid pressure is removed and fluid communication between the filtration chamber and the water accumulation chamber is restored.

Automated water drain system

Lift pump guard for a pump operable by an electrical motor. The lift pump guard monitors variable parameters and actuates a relay to electrically terminate operation of the pump motor when the pump is dry running. Also a method of protecting a pump from dry running compares a measured parameter to a predetermined value and terminates operation based on the comparison.
