With or without a speedy-bleeder-type type device, I use this inexpensive
one-person bleeder kit to catch the fluid and to look for air bubbles in the outflow-line.
A hose from the bleeder into a catch-bottle is all that is needed to see if there is air in the fluid in the hose (I assumed that a "drain hose" was being used in my earlier one-person response - sorry).
