We supply a wide range of pool pumps for domestic and commerical uses. Just as there are in-ground pools and above-ground pools, there are different types of pool pumps created for each type of pool. Using one type of pump meant for the other is not a good idea. For example, an above-ground pool works by feeding water to the pump's intake via gravity. These pumps may not function very well if water is not fed via this method and would likely be minimally effective with an in ground pool.
