Thanks Jeff and everybody else. I spoke to the
vac. repair man and I'm wrong - it is not psi.- it
is inches in water.
whoever suggested the leaf blower, many thanks!! i just got a 2 3/4" rubber ball my grandson dropped into our 3" outdoor drain! tried everything without success. was going to rent a snake, then filled the pipes, leaf blower fit perfectly into the drain pipe, water, debris and the ball all came shooting out of the end. yay, saved by butt!!

This is outrageous. Sue the original plumber. A 2 3/4" ball should
have fit easily in a 3" pipe.
