Sand filter questions

I was looking at an old post about recirculating the water....
If I think I may have a broken line in my filter, could I vacuum the pool (maybe to waste) then put the setting on recirculate instead of filter to see if what shows up is algae or sand?
Would that work?
Thanks for any suggestions,
Kerrie

Kerrie, that sounds like a very good plan to determine where the possible issue is:)

Thanks for the support!!!!
I'll update in a couple of days.
Thanks agian,
