Having trouble with roof repair. I have questions about the pump. I have the pump in a vertical position in a vice. I took off the reservoir container looked at the openings. All looked good to me. Took off the motor and the made sure the rotating mechanism on the pump side rotated both ways. It did. Put it back together and got the same result as before. Strong stream out of 12/14 nothing from 11/13. Change the leads 12/14 sputters, nothing from 11/13. Can't find info on correct way to test pump. Not familiar with the internals of a pump, thinking of using air gun to blow out ports possibly there is a blockage. Unless there is a more acceptable method. Suggestions are welcome. Maybe its at the point of getting a new pump if they are around.
