Winterizing an Inground

[mamcwifey]

Trying to get a jumpstart on the winterizing process for my 20x40 inground liner pool. Most of my pool experience comes with above ground pools, and there's obviously not as much to closing an above ground.

I'm all set on the chemical side of closing, but I'm not sure about what to do with the lines and also the best way to put (and keep!) the cover on!

Any suggestions/instructions/help would be greatly appreciated!

I'm still hoping to get another 3-4 weeks out of the pool, but I want to start preparing for the close.

Thanks!
