This shows my ignorance about mechanical devices in general, but could powerheads lose power over time?...i mean could a 1000gph powerhead go down to a 800 gph powerhead from regular use over time...this is in the scenario that it has had proper upkeep and cleaning
used powerhead flow question
- Thread starter hammcd
- Start date
When in doubt, throw it out......
It's stated GPH is less important the apparent flow, and most powerheads are had fairly cheaply.
Answering your question, I think the impeller can get worn with regular use, and therefore move less water, but from what I've seen, either they work or they don't

Over time bearings and things can wear out even with proper maintenance. It is possible that the impeller is worn or that any of the internal components that you wouldn't normally come in contact with are worn as well. If the reduced flow is sufficient for you, then there's not much of a problem. But reduced performance can be an indicator of an impending failure.
To answer your question simply, most things are designed with a "reliable life" that is not infinite.
Edit: Be sure you're placing the proper blame. Any buildup in the return line would reduce flow. Also, changing the flow path (height, number or types of curves, pipe diameter) could change the flow rate.
