With that much pressure in the tank, you shouldn't have any flow
problems at any outlet even using 2 at once. You have blockage
somewhere after the tank or a valve that is only partly open. It is
possible that the blown bag is allowing full flow into the tank and
then at least partially blocking the outlet for outflow, i.e., acting
like a flapper valve.

Good call, Harry -- that just might be the explanation.

Yes, it could be. Also, with the broken bag, the volume of air in the
tank is different from what it would normally be, FWIW. I plan to
call a water system guy tomorrow.

Ahhh, never mind calling the water system guy, just replace the stupid tank.
That's what he's going to do anyway. Might as well replace it yourself and
save the cost of a service call -- it isn't rocket science. Anybody who can
use a wrench can replace a pressure tank.
