Hello Bert,
Yes I did check that all the ports are still clear and open,
The ice has also not formed since it was first seen on Wednesday (5/7)
Also there is no evidence of any water trails/ stains, having been left on
any of the locations mentioned.
Thank you for your help and list of things to check.
Sincerely,
Silas
