Sand filter crack - repair or buy new?

Hey all. We have a Hayward s244t (300lb sand) filter that‘s ?? Years old. We bought our house with pool about 7 years ago, and (I know, I know) have done little filter-specific maintenance. We replaced the sand about 3 years ago on the recommendation of our local pool store, and backwash when needed, etc.

My toddler tells me “I hear a weird sprinkler noise but don’t see the sprinklers on” a few nights ago, and I find a large crack spraying out from below the neck of the filter. I’ve read that crack repairs are fixable, but I also read that there are all kinds of parts in this filter that need maintenance and upkeep, none of which we’ve done. Are we better off repairing this filter, or getting a new one (we have it in our current budget / pool Reno plan to purchase new, but just need opinions on if it’s absolutely absurd to not fix it). Any thoughts?

Welcome to the forum!
Pressure vessels should be replaced when damaged, never repaired.
Your filter vessel should be taken out of service, now. The force that would occur if you had a catastrophic failure could harm person or property.
I suggest you read ABC's of Pool Water Chemistry.

Thank you! It’s off and has been off since Niagara event 😉. I’ve been through ABCs of chem (link), but didn’t see anything about filter. Is there something I’m missing?

My filter made from polyethylene, same material as chlorine and acid bottles, car gasoline tanks. This material chemical resistant.
Gluing is possible, but glue is expensive, it hard process and it not hard enough. You can try to fix gasoline tank, that can cost $thousands, but not a filter under high pressure.
