Hi Everyone! May I please get some feedback about my pipe design (the return portion)? It is has the T that forms a sprinkler. And the swing check valve down below the T.
May I please ask does anyone see any design errors? This is my third season. This past winter I did not get the water out and it froze and cracked all the way down below
the swing check traveling all the way beyond the T just short of the valve. Thank goodness. But a bummer too. Every year I have had some freezing so I realize I need to learn
about winterizing. I have a new compressor so maybe I need to use that in every open ended place I can find. However, the outlet into the pool has a cover that has a screen
face on it and I am not sure where I could apply air pressure. And the swing check valve prevents water flowing downward. Do I really need a swing check valve here? If the
water was allowed to move downward why would that matter? And the really strange thing is that I never did anything to remove water from it during year 1 & 2 and this year
it was full of water - as soon as I cut the pipe the water spilled out. I can't understand how the water was not caught in this location year 1 & 2 if I did nothing to remove the water.
Thank you very much.
