Review on 💧 The Basement Watchdog BWE 2,000 GPH Emergency Battery Backup Sump Pump System: Reliable Protection at 0 ft. and 10 ft. by Randy Bin

Attention buyers! This backup battery drain pump requires a proprietary battery that costs much more than a standard battery (dry battery plus acid), requires service every six months, and has a shorter lifespan than standard batteries. Battery life is also shorter than a standard battery. This means that at a big event (like Sandy had a few years ago) the battery will not last for the duration of the event - and to be on the safe side you have to get an overpriced second battery. BIG MISTAKE!
