I have an Intex 12’ metal frame pool with 1.25” lines. I want to purchase the Intex Automatic Pool cleaner, but it says I’ll need the Intex pool with 1.5” lines to connect the vac adapter correctly. I don’t want to cut my liner to add a 1.5” Intex inlet. Is their a part that will screw onto the pool inlet that will then accept the vacuum adapter so I can run it? I have an upgraded pump to support the gallons per minute requirement.
