This sump pump is the reason that the homeowners initially called. The pump had failed on numerous occasions and it was very frustrating for the homeowners to walk into a wet basement.
Daniel recommended a SuperSump sump pump. It's a rugged, powerful pump from Zoeller with an antimicrobial plastic basket, rigid cover with drain, battery back up, and WaterWatch alarm to notify the homeowners if the sump pump isn't working or is overwhelmed.
