Hi,
The Regional District I am working for here in Canada, owns a few water main lines buried above ground from the 70' and 80's. These lines are wrapped in a heat wrap to prevent the main from freezing. With the extended period of cold weather we had in January, I worry the 50to 60 year old heat wraps are not working. Does anyone know what the estimated useful life for watermain heat wrap is?
Thanks in advance,
Silje
