Answer
Thank you for your interest in Water Pumps Direct. Per Wayne, the TSC130 will handle a 50/50 duty cycle. For most jobs it can complete the task. If there is a large amount of water, run for an hour and rest the unit for 20 minutes and re-start if needed. Extension cords should not be used. If you absolutely need an extension cord, use the shortest length possible with 12 or 10 gage rating to insure that the pump will not overheat.
