Just some friendly info. I was able to adapt my Summer Escapes 16" x 48" pool to the Intext 2650 sand filter with just the following FOUR parts: (Of course you will need two 50lb bags of pool sand from the dreaded pool store preferably.)
http://www.amazon.com/Summer-Escapes...kimmer+adapter - Allows you to connect your Intex sand filter inlet to your existing skimmer and eliminates the cheap stock pump. Requires a hose clamp just over 2".
http://www.lowes.com/pd_192069-1003-...ductId=3151503 - Connects directly (pressure fit) over you exsiting return inlet, and Intex hose clamps to the fitting. Requires a second hose clamp just over 2".
http://www.lowes.com/pd_55349-33599-...ductId=3878544 (2 pack) - Used to connect the Intex hoses to the above two fittings.
As far as the screw on connections, I slid them back to the pump over the hose in case I decide to hard plumb at some point.
The pressure fit on the return side is very tight. I have been running the pump for a while now and it has not tried to come off. You could always PVC glue the fitting for a more secure fit. I have not done so because I thought maybe I will come up with something better eventually or hard plumb the lines at some point.
Hope this helps some folks out there with Summer Escapes Pools.
