20 March 2024 I temporarily installed my pump yesterday. The pump, to the best of my knowledge worked continuously for three hours and twenty minutes (3 hrs 20 mins). At the end of that continuous period the pump was hot but still pumping water normally. Since I propose to use the pump one hour on and two hours off during daylight hours the performance yesterday is satisfactory to me. The pump seems to be pumping just over 4 GPM. On Friday/Saturday I propose to use a five gallon container and conduct an exact measurement. Will update thereafter. I will provide periodic updates when the pump is installed permanently. I will update my Star Rating after some permanent use.
