Any idea what is causing the motor to not stay at the steady rate?

Back pressure? How do you relieve the pressure?

The problem does seem to be the backpressure... but its strange.

When I first turn it on it will work for a good minute or so, then it
will start going into "struggle mode" for a few seconds, then it will
go back to normal. It will alternate between the two states for awhile
and then it will just settle at "struggle mode".

Struggle mode is when its RPMs lower and it doesn't pump enough (bad).

How can I fix this?

Thanks a lot
