Need advice for an exterior sump pump
Does anyone know if there is a sump pump durable enough to be installed outside in a window well? I live in the Midwest where the temperature drops below freezing in the winter.
Steady periods of rain (6+ inches in a couple days) will cause water to slowly come up through the bottom of the window well and spill into the basement around the frame of the window. This only happens about once a year, but it involves a finished part of the basement.
I have observed during these heavy and prolonged rainfalls that water will tend to pool about 10 feet from the window well. So I also intend to put a french drain along the back side of the house.
I would like to dig down in the window well and install a sump pump, in case the french drain idea does not solve the problem. An outdoor plug receptacle is about 20 feet from the window well.
Is this a workable idea? Are there outdoor sump pumps that are made to withstand winter weather? I do not anticipate any water in the window well except during the spring and summer when the area receives heavier rain.
Any advice is appreciated, thanks!
I think I found a solution
Thanks for the advice everyone!
I had put new covers on all the window wells a few years back, so its not the rain falling in. I've also seen the water rise in the well (very slowly, like watching the hour hand on a clock) after the rain has stopped.
I went ahead and dug about 2 feet below the window sill this weekend to find that it was filled predominantly with clay, topped with about 2-3 inches of river rock... from what I've researched, this seemed like an issue. I filled it with clean 3/4 inch gravel, surrounding a perforated 5 gallon buck. I intend to put a small sump pump in the well and bury the discharge line leading to the french drain in the yard.
Come winter, I'll pull the pump out and put it in storage. I just need to make sure I assemble the discharge line in a way to make it easy to disconnect. I'm hoping that the french drain keeps the water away from the window well all together, but the sump pump should provide a pretty good "safety net".
