Zoeller M53 cast iron submersible sump pumps are virtually indestructible, and paired with a 3G Cellular Pump Alarm, your can rest assured your basement or crawl space will stay dry. Pump Alarms can text up to 3 different numbers when your power goes off and back on, when the water level in the crock reaches undesirable levels and returns, or if your water heater tank fails. There is an optional sensor (for additional cost) to notify you if the heat drops below 45 degrees Fahrenheit. Go away with peace of mind every time you leave your home, because these 3G Alarms work even where cell phones won't. Underground downspouts keep water far away from your house, and you never need to mow around or worry about your downspout extensions coming off. They also make great discharge options for your new or existing sump pump.
