    Which plugs for return lines for closing pool

    the return lines will still be under water level.

    Should i get the standard white threaded plug with o ring
    OR
    the cone shapped rubber expandable style plug?

    Thanks,

    For threaded fittings the threaded plugs with o-rings work much better. It's almost impossible to get the expanding plugs to seal the threads.

    Ok, sounds good.
    I used the expansion ones in past as well as the threaded plugs. Anything on the threads like teflon tape to keep them from getting stuck come spring?

    It may help, but only use a wrap or two. I'd probably just put some pool lube on them if I had it handy.
