AW-Pump installs and services both pedestal sump pumps and submersible sump pumps by Zoeller. Pedestal sump pumps have the motor mounted above the sump, making it easier to service and maintain. However, more accessible to service, this type of sump pump is more conspicuous and can be more in the way, primarily when used in a finished basement. The second type of sump pump is a submersible unit. Submersible sump pumps are mounted entirely inside the sump and sealed to prevent short electrical circuits. Since this type of pump sits within the sump, it may require additional effort when servicing and maintaining your unit. Still, they are often more effective and more easily hidden if you have a finished basement.
