This is a video showing the pump and filter system we use on our above ground pools. We use a combo system from Hayward that is the pump and filter combined.
The pump is a 1 1/2 horsepower Power Flo LX pump. The filter is a 150 pound sand filter with a topmount multiport head. This system is one that we use on pools up to 27′ round and 15×30 ovals. If we do sell a pool bigger than that size (which we actually discourage) we bump the filter up to a 200 pound filter. You want to make sure that the filter system is sized right to be able to turn over the water volume in your pool in less than 8 hours time. I did a blog on this you can read here.
Take a look at this video and you can see exactly what type of filter system that you will get when buying a pool from Edwards Pools. You can switch to a cartridge or even a DE filter if you want. In our experience though sand is the easiest way to go for the least amount of headache.
You will notice the 3 way valve plumbed in the front of the pump. One side is plumbed for the main drain, with the other side pulling water from the skimmer. This is how we plumb all our systems.
Enjoy the video!!
