Review: Worked fine through hurricane Milton. Here it is about 9 months later had a big rain and it did not automatically start up. I tilted it and it started right up. The float was not rising to the top to activate the switch. There was an air pocket in the front float area so I removed the float area cover and drilled 4 small holes in it to release any air that may get trapped in the chamber around the float. Started filling the pit with water and the pump came on automatically. Tested 4 times, looks like the issue has been resolved. The cover that is around the float was set in there so tightly that no air could escape. Just in time for the next hurricane season.
Review: Extremely satisfied with the Pump. My question is it sturdy enough to spend the winter underneath my deck ? THX

## Features

- Kindly Tip 1: When you start using the pump, it must be fully submerged in water at a slight angle and hold it underwater for 20 to 30 seconds to ensure all trapped air is thoroughly expelled before operation
- Kindly Tip 2: The device is not suitable for continuous operation (e.g.as recirculation pump for ponds).This type of use will substantially shorten the pump's life expectancy
- 1HP High Power: Prostormer Sump Pump uses 1HP power, which is more efficient than ordinary 3/4HP sump pump; Max 3500GPH rating tackles any draining job at a fraction of the time
- Multi Outlet Sizes: 3 different diameters outlets (1 inch ,1-1/4 inch, 1-1/2 inch) to adapte for different size hoses as needed according to the flow rate. The bigger the flow is, the wider the outlet should be
- Manual Mode: Set the switch to the MANUAL positon the pump will now not automatically switch off but carry out pumping, even if theremaining water level is reached and the pump runs dry. You should cut off the power immediately to prevent the coil from getting burned.Automated Mode: Set the switch to the AUTO position. Once you have plugged the device into the socket, the pump will switch on automatically when the water exceeds the start-level and switch off when the stop-level hasbeen obtained.

*by A***Y on 23 August 2024*

UPDATE! 7/16/2025 After almost a year now we guesstamated over 800 hours and it still pumps water. This pump in on a concrete block 2' 19" deep inside a 55 gallon drum with the top cut off and the bottom side up with a hinged door. It has pumped sand and leaves with more water than I can imagine from storms, hurricanes and a broken pipe for a week. I am buying another one just like it to be sure we don't flood out. After all that it has done I can not trust it to keep going. It has paid for itself more times than I can count. Used it for an automatic lift station for my new french drain. Out of the box it pumped far more water than expected but the auto would not function without shaking the pump. This was during a 4 inch downpour. Took it out of the hole, tinkered with the float and it began the auto great as seen in the video. Checked it today and the hole was filled, pump completely submerged. Shook it and bang! It began working perfectly again. The problem is, I am not going out in a Florida thunderstorm to kick-start it every time. I'll keep it for something later, but it's getting replaced with a REAL, reliable automatic sump pump.
