hi again guys so I just got in my new intex 633 pump and it was a deal on amazon for 100 bucks including the plungers and valves...my pools the 14 foot ultra frame so it has intake/outlet holes for the smaller 1000 gph pump. ive read that I should use the gasget from the plunger, place it on the wall of the pool and use a sharpie to trace around the inside of the gasget then cut along the outside of the sharpie line and then assemble things....is that right?...tips, help...please this is my first time doing it and I might do this Thursday if not sunday when im off and im nervous about it....thanks
