I blew out all returns and plugged them-no problem.
With the skimmers I sucked out as much water as I could with a vac, blew more water from the pipes into the skimmer, sucked out more (rinse repeat) until I could no longer get water to blow into the skimmer any more. I then dumped some anti freeze in the skimmer pipe/plumbing.
Is this correct?
Then I screwed the gizmos into the NON-PIPE threaded hole in the skimmer. Is this correct or should it go into the pipe/plumbing hole? (They are a different thread that the gizmos I was given.) I am not even sure what the gizmos do, I just cannot afford a burst pipe on my 1 year old installation.
