Trash pumps are non-clogging up to what size?

Explanation:
Trash pumps are built to move water that contains debris without clogging. Their design features a larger intake and wider passages so solids can pass through the pump instead of getting stuck. Because of this, portable trash pumps handle debris up to about three to four inches in diameter before the flow slows or clogging risk increases. Debris larger than that can jam the impeller or reduce pumping efficiency, which is why this size range is the practical limit. The smaller option would not reflect a true trash pump’s capability, while the larger options exceed what typical portable trash pumps are built to pass.
