I just have a couple of education questions.
When looking at the TPR installed on my hot water heater, I noticed the drain is a copper pipe, soldered to a threaded fitting and then screwed into the TPR. Standard 15 in the 25 Standards section says that a TPR discharge pipe should not have a threaded end. Is my situation ok because it is a pipe soldered to a fitting? Is the standard stating that the pipe shouldn’t be something like threaded gas pipe or something similar? Lastly, would a PVC pipe glued into a fitting, and then threaded into the TPR be allowed?
When describing the location of the main water shut-off valve, I understand describing the shut-off in the house, after the water meter. My house also has the metal cap in the yard (near the curb) that you need the four-prong tool to turn the water on and off with. Is that shut-off strictly for the city to use? Do you describe the location of this shut-off in your reports?
Thanks for your help
