What is the difference between a unit for IG vs AG

[mas985]

As to using an AG pump on a IG pool, it is possible but it depends on the installation height of the pump relative to the pool water (above or below and by how much) and/or the pump line. However, there are some AG pumps that self prime such as the Pentair Dynamo and Hayward Power Flo II that would work fine with an IG pool. But most AG pumps require a flooded suction.

Also I would not recommend using an Intex type of SWG and pump combo if that is what you are thinking. They are significantly under powered and definitely require a flooded suction.

FYI: "flooded suction" = the pump is below the level of the pool's surface, and the piping is arranged so water will flow naturally by gravity into the pump.

Sorry I was talking about SWG and as to weather we can use a SWG intended for an AG pool in our IG pool. We have been using SWG but it needs to be replaced and because AG units are less I was just wondering if I can purchase an AG as a replacement. We currently have a Circupool RJ series. Had nothing but problems with it.

The only issue with an AG SWG (without a pump) is that the size can be small which might force you to run the pump longer than you want so it could end up costing you more in end. The larger the SWG, the better because it means you can shorten the pump run time and save on energy costs.
