Water ingress into SmartShepherd pod in extremely rainy conditions.
The o-ring specified for most SmartShepherd customers is not sufficient for pods immersed in water continuously - the supplied o-ring is slightly undersized and needs to be moved to make it more effective.
Grab the collar with an o-ring and squeeze the o-ring from the sides until it can be removed.
Take the o-ring and place it inside the SmartShepherd pod,
Carefully push the o-ring into place in the base of the pod so that it sits underneath the pod threads..
In this position, the o-ring is squeezed sufficiently to have better waterproofing properties in service. The placement of the o-ring also helps with pod retention in service.
Screw the pod back onto the collar until you can feel that it is snug.
