If your water line is only 18" deep, your in deep trouble !
Who ever installed that didn't pull a permit and should be tared and feathered !
I live near Boise and code here is a min of 42" deep.
Yea.. I hate working on this building... The city of Idaho falls has NO permits on record period for this property... Last week I actually had to fix the cracked pipe that thawed out. Luckily I was able to chop it and remove the line feeding my house and I installed a berry hydrant on the other side of the parking lot. Then I tied in the cold water from the apartment next door (I don't know why the Hell this wasn't done in the first place!).
I started working for a plumbing/HVAC company in Shelley and on all our jobs we are burying the water supply at 7' below grade. And the crazy part is we still had one freeze up on us at that depth!!! This cold weather is harsh on everything!
