A pre-filter will help a lot. Mine seemed to deliberately do that just as I was settling in for the night and was in no mood to clean a filter.
One sign it's soon to happen: look at the water in the intake tube side - it should be flowing smoothly. If it's at all turbulent, it's a sign you have a clogging sponge (the water is rerouting).
