Here is a link to a great video that I train all of my staff with. It goes something like this:
Cut the pipes, debur inside and outside edges, check the fit (male fitting pushing 2/3 of the way into the female is perfect), primer onto female side, primer onto male side, glue onto male side, glue female side and glue male side, push fittings together and 1/4 turn. I just finished a commercial plumb job with 700 connections and didn't have a single leak using this method. You shouldn't have a problem using the grey electrical pipe and the white pool pipe.
