If you have a built in recessed cover on your pool you have to get rid of the water on top when it rains or your cover will eventually end up damaged or at the bottom of the pool.
There are many auto sensing pumps on the market but the Little Giant APCP-1700 Automatic Swimming Pool Cover Submersible Pump, 1/3-HP, 115V that came with our system is “top notch.” It’s ~$147.99 but a small price to pay for peace of mind for your cover when it’s pouring outside.
Simply place on top of your cover and aim the spout away from your pool & house and leave it plugged in. When the unit senses about 1.5 to 2” of water, it sprays a plume of water about 20-25’ away from the pump and automatically shuts off until the water height comes back up.
The Little Giant APCP-1700 Automatic Swimming Pool Cover Submersible Pump has some really great specs and performs day and night, hot or cold, rain or shine (…especially rain).
Things I really like about this pump….
Note: the pump de-rates to 500 gallons per hour if using a garden hose on the output side due to friction losses.
In our application somehow all the water finds it’s way to the pump and within a few hours after a strong rain the cover is almost completely dry again with just a few wet spots like nothing ever happened.
