Why the HP Rating Looks Unusual
The 1.0/0.12 HP rating is normal for spa motors:
-
High speed (1 HP): jet action, strong flow
-
Low speed (0.12 HP): quiet filtration and heating mode
This is standard for dual‑speed spa systems.
Replacement Notes
When installing a new motor, you should also replace:
-
Shaft seal (specific to your pump brand)
-
Housing gasket
-
Diffuser o‑ring
A worn shaft seal is the #1 cause of early motor failure.
