Yes, I have cleaned the strainer using a stiff wire and pulled a lot of plastic bits and aluminium shavings from there, then I flashed it with varsol to make sure that he pipe is clean inside. Everything seems to be pristine clean. The only my concern is with the strainer screen slightly tilted inside its housing (not flat against the bottom plate). Is the strainer screen in your new suction pipe positioned the same way or it is mine still have bits of plastic jammed at circumference not allowing the screen to seat flat?
Thank you.
