back flush the motor and install a new impellor.

Wow great video... So the input hose is the one to run the garden hose to back wash??

Think man THINK!! If you are trying to BACK flush, to flush something out that could be blocking a passage you would REVERSE the normal waterflow. So if you are reversing the waterflow the input hose would be the output.

i am thinking pal i run 55 employees in the automotive bussiness masonire.net and this is very differant.... im sorry im not retarded just want to do it correct??? the video is a little differant set up but how do i know which one is the input/output

masontire.net

I didn't say you were retarded, I said to think about what it is you are trying to accomplish.
