Thanks Glenn. I finally decided for something more permanent. I went to Home Depot and bought some Pex tubing, fittings, clamps and the clamp tool. I also ordered a three way valve on line and modified the plumbing so that now I only have to switch a valve to suck AF into the system. And while I was at it, I used a couple more three way valves to plumb in a bypass for the water filter. It makes the job much quicker because we occasionally have to dewinterize and rewinterize a couple of times in the winter. The Pex tool was a little expensive at $62 but it made the job easy and now I have it for any other jobs that may pop up.
Edit...I removed the mods that I had done in a previous post. This is a much neater job.
