hole in sand filter tank

[ScottS]

I have a Pentair SD-60 sandfilter that developed 2 elongated slits in the side last week! Our pool and equip is 2 years old. Will be receiving new tank from Pentair!
Thank goodness!

Please tell me the secret on getting a new filter. I attempted but they wouldn't budge. It still frustrates me because there is no reason it should have cracked.
If possible I'd like to get some details from you so I can still attempt to get the tank replaced.

Thanks!
