Rear window washer

[Deboltboy1394]

I'm sure this has been posted before but I'm new to the forum. I can hear my pump working like an SOB but not spraying my back window. Could that just be a bad hose or more then that?

Busted line, plugged check valve, plugged sprayer, low tank (rear sprayer pump draws from about 1/2 way up tank as opposed to front sprayer from near bottom....)
