- Be first piped to an indirect waste receptor such as a bucket through an air gap located in a heated area when discharging to the outdoors in areas subject to freezing, since freezing water could block the pipe.
I would remove the bucket part. Are there buckets specifically for this purpose? :shock:
Seems an air gap in a heated area would prevent the pipe from freezing (with or without the bucket) ;-).
