It sucks w/o the filter in place but then speeds up and doesn't suck
at all with the filter in place.
I cleaned up dirt and water in the garage once and left the debris on
the filter for two months.
Today, I ran water over the filter to make it white again, but it
looks somewhat opaque.
Is it possible I have permanently clogged the pores?
I haven't let the filter dry out yet. Is it possible it will pass air
when it's dry and I can tap it to loosen any remaining dirt?
I checked the blue foam "final filter" right at the entry to the pump,
but it's pretty clean. I washed it and blew it out gently and it looks
I removed the check ball that closes off the vacuum when the tank is
full but that didn't help. Any suggestions? Otherwise, I am going to
buy a filter on ebay for $14 + shipping.
