💡 What causes mechanical seal failure in water pumps over time?
You should watch for leak tracks that show up near the main housing.
Normal friction eventually eats through the mating surfaces.
Here is what you will spot on a tired setup:
- Steady damp spots under the base show cracked carbide plates
- Harsh grinding sounds mean lubrication films stripped away
- Brittle rubber rings confirm heat baked the original compounds
- Weak output pressure points to deep scratches on the carbon seat
