Welcome to the forum!

You might do well to invest in 2 Hayward SP 722 valve with a male adapter thread and a female adapter end (I'm going from memory on the part # ) These will thread into the bottom of the skimmer and the return fitting and allow you to reuse the existing fittings to connect the hoses

If you want to 'hard plumb' a couple of 2 way valves into the system, we can certainly help you with PVC plumbing methods and techniques
