I live in southern Ohio (US) (16k gal ingound/vinyl, 5 returns, skimmer & main) and looking to close for the first time myself
. Here are the steps I've outlined to do (hopefully creating a repeatable process!).
Prepare The Water:
1. Vacuum one last time
2. Get chemicals to correct settings
3. Backwash and rinse one last time
4. Lower water to 2 inches below skimmer (using main drain)
Prepare The Filter:
5. Remove the site glass from filter (near top) and store it
6. Remove the drain cap from filter (near bottom) and store it
7. Remove the backwash hose and clamp from the filter and store them
Prepare The Pump:
8. Remove pump drain plug (near bottom of pump) and store it
9. Remove the pump basket and store it
Prepare The Return Lines:
10. Remove all return eyeball jets (5) and store them
11. Hand tighten 90 degree elbows in each return (may need Teflon tape). The longer ones go into spa jets near steps.
Prepare The Skimmer:
12. Remove the skimmer basket and store it
13. Insert the Gizmo (may need Teflon tape)
Winterize The Pool:
14. Insert compressor quick-connect fitting to pump drain (near bottom)
15. Set filter to recirculate
16. Blow one line at a time using valve controls (check pressure!!!)
17. Place a half gallon of antifreeze in each line (only main drain?)
18. Place a small empty jug/bottle in skimmer itself
19. Place empty plastic jug in skimmer door (forcing skimmer door open)
Cover The Pool:
20. Raise all pool cover cleats around pool deck
21. Place cover into position
22. Place one long side into cleats
23. Use cover bar to stretch other long side onto cleats
Now for a few questions:
Step 4: Is 2 inches about right? Note: I have 90 degree elbows that are placed into the returns to bring them above the water line.
Step 16: I plan on closing all the lines (7 total) at the pump before blowing each one at a time. Is that OK? Once a line is blown, should I immedately close that line for the winter and leave it closed?
Step 17: Is a half gallon of antifreeze per line about right? Should I use antifreeze in all of the lines?
Step 19: Do I need a plastic bottle to prop open the skimmer door for the winter? Seems the pool store did that last year.
Anyone see other issues with this?
All advice is greatly appreciated!!!
Thanks in advance
Tim
