Pedestal sump pumps were previously the most popular type of system utilized in homes. However, pedestal pumps can become noisy since the motor sits above the water. This also means that it’s at a higher risk of overheating. Pedestal sump pumps made of cast iron tend to last the longest, but keep in mind that they cannot remove any debris sitting in your sump pit. Generally speaking, if the sump pump pit in your basement is too small or shallow, then it’s best to install a pedestal sump pump.
