Got to agree with this. But the fix is sometimes just something simple like an item we stored in the wrong spot may be pushing the plumbing attached to the pump against a cabinet wall. Hard to fix remote as it requires some listening to the sound and where it might be coming from. Looking at the pump while using it can help spot things like one mounting being loose so it jumps around.
