We have a spa pump that is leaking out the pump. Wondering if the o ring is the only part that needs replacing or whether the complete housing should be replaced as well. It appears to be leaking at the o ring. The part number is 177782 Cat BN37.
Hello Christine- It sounds like you could have an o-ring issue or shaft seal issue. We would need to know the model of the pump, not the motor to determine which seals you would need. If you don't have the model of the pump you can send us a picture of the pump to firstname.lastname@example.org.
