PVC and Unions

[SCBillsFan]

I want to replace the sand in my sand filter, however, the multiport valve is hard plumbed without the use of unions. Should I cut the PVC a few inches out and away from the multiport valve? Or am I overthinking this? Seems like that would be the most logical thing to do. Also, can I just buy the unions from Home Depot or do they have to be purchased from Hayward (which I've been told was the way to go, but seems like it's the same thing I can get at Home Depot for about 1/3 of the cost)? Any and all suggestions appreciated!

Once you cut go for the unions so the second time around is eezy peezy and yes for the home depot unions.

Changing sand in Hayward filter question

Hey folks, Need to change the sand out. Do I need to cut these PVC pipes or can they be unscrewed? I didn't instal the filter. Looks like it's glued, so assuming I'll have to cut the pieces? Thoughts? Thanks!

Better to use pool unions from CMP….
