How often should a water pump be replaced?

Hey there! That's a great question about water pump replacement. From what I've found, the replacement frequency really depends on what type of water pump you're talking about:

For car water pumps, the general recommendation is every 60,000 to 100,000 miles. Many mechanics suggest replacing it when you change your timing belt, since they're often connected and it makes sense to do both at the same time.

For home water pumps (like centrifugal pumps), they typically need servicing every 1-2 years depending on usage and water quality. Regular maintenance includes flushing and inspecting the pump and pipes, and checking the pressure tank.

The key is to follow a regular maintenance schedule to catch issues early and prevent major failures. Are you asking about a car or home water pump specifically? That would help me give you more tailored advice!
