CT, HARTFORD
Narrative
The state has experienced a large amount of accumulated snow this season. The customer at this facility had removed snow accumulated on the roof out of concern that the snow load would collapse the roof. The snow was removed from the roof and deposited on the ground surrounding the building including the meter location. When company personnel arrived onsite the snow at the meter set was 10 feet high. The force of the snow being dropped from the roof stressed the piping from the meter valve at the top of the service riser to the regulator causing the threaded nipple to crack at the threads.
