I dont know where should I place this thread, but I am looking for a place in Calgary (if there is any ???) where I can get some check valves like
True Union Swing Check Valve - 1/2 inch Slip x 1/2 inch Slip ( or 3/4, 1" even larger...)

Last time I went to LA for a wedding and so bought some there, but didnt think about needing some more now for another new setup.

Thanks in advance.
