A&W Pump installs and services both pedestal sump pumps and submersible sump pumps by Zoeller. Pedestal sump pumps have the motor mounted above the sump, which make it easier to service and maintain. Although easier to service, this type of sump pump is more conspicuous and can be more in the way especially 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 are specially sealed to prevent electrical short circuits. Since this type of pump sits completely within the sump they may require additional effort when servicing and maintaining your unit, but they are often more effective and more easily hidden if you have a finished basement.
