Water gushing from top of filter

[panamamyers]

Just recently got a pool installed dnd working my way through understanding the upkeep.
I have a Hayward cartridge filter swimclear c100s I believe is the model.
Having trouble getting the builder back out so sort of on my own at the moment. They left it so dirty that I have had to take the cartridge out and clean it multiple times. Today I took it out and cleaned it and when I put it back and rotated the top back to lock it, water just gushes out of the top between the top and bottom pieces. I have undone it and screwed it back on several times. It was working reasonably well(at least not gushing water out) prior to me cleaning it. Just a sudden change within five minutes to all of the water from the filter flowing out into the yard.

Any thoughts on what could be the issue?

Did you lose a gasket or damage it by chance?

Pan,

Show us some pics.

Especially the lock ring, or whatever hold the top on.

Edit.. Did your builder fly in from Florida to install that filter...

Edit... Do you have an above ground pool, or an in ground pool??

Thanks,
