Do you need to get a specific pump? Don’t worry, there is a way. Let’s discuss this, and go over your options in this blog post.

Making your new above pool pump connections work

Most often, above ground pool pumps use standard 1.5-inch internal diameter ports. There are pump models that use unions that thread to the outside of the ports. Those unions are which are part of a hose assembly. These types of arrangements are most often designed by the original manufacturer of the pump/filter system. Those systems are packaged together by the manufacturer and use those hose assemblies. Most often, the filter is a sand filter. Here’s the catch – those thread designs are specific to ONLY that manufacturer. This means that they are proprietary. In order to use a new pump when you have an existing system of this type, it must be one of these two: 

  • The same manufacturer and/or brand
  • Used with an adapter or PVC accessories to connect the pump to the filter
