Draining for the new Liner

[DLaplante]

20 x 40 IN ground need to drain it for the new liner, is it ok to use the main drain and the pool pump to drain it?

I was planning to set the spider valve to waste and just drain it in the back yard we have a pond that can handle the water.

Bummed also, as I added borates last year now need new liner...

If you can isolate the main drain from the skimmer, absolutely. If you can't, as soon as the skimmer goes dry, you start sucking air and everything will stop.

Yes I can turn off the skimmers, and leave just the main drain open. My profile picture shows the valves.

Would setting the spider valve to waste be the way to go?

Yes. Then you're just pumping water straight from the pool out the waste pipe. The filter is taken out of the loop completely.

Very good thanks for the info. I'll be pulling that old liner out this weekend, then the real project starts.
