I have a tagelus ta100d tank, and Pentair TM-22 multivalve. On every video I’ve watched on how to change the spider gasket, they always say you need to bleed out the air pressure from the filter. However neither my sand filter or multivalve have a bleed valve. However neither do I do this, or do I need to be concerned about it. Thank you in advance.
 
Welcome to TFP.

The TA100D filter does not have an air relief valve, and no guidance is given on what to do instead.

Turn off the pump and wait a bit to let the pressure drain out of the filter. Slowly loosen the MPV screws, and any remaining pressure should be released.
