Shaft Seal Kit
The mechanical shaft seal provides the dynamic barrier between the impeller and the motor shaft. Over time, chemical imbalance or heat caused by running the pump dry leads to the degradation of the ceramic and carbon seal faces. Once the seal is compromised, water travels down the backplate and drips from the bottom of the pump assembly.

Seal Plate O-Ring
This large-diameter O-ring creates a static seal between the motor seal plate and the pump volute. If the O-ring becomes 'squared' (set) or brittle due to age, it fails to maintain compression under the high pressure of operation, allowing water to escape through the housing seam.

Pump Housing (Volute)
Documented failure patterns on TriStar models show the potential for stress fractures or thread deformation at the discharge port. If the leak is originating from the top threads but manifesting as a drip underneath, the housing material has likely experienced structural fatigue or hydraulic hammer damage.
