I am looking for information regarding the use of flexible water heater supply line (copper corrugated with brass nuts and rubber washers) as the discharge line on a water heater.
The device clearly says that it is a "water heater supply line", but I notice that plumbers and people use them for the water heater discharge line also. To make matters more confusing, a home center store used to sell a "water heater installation kit" that gave you two of these devices. That would seem to imply that one goes on the discharge line.
The supply line device uses a rubber washer on each end, but there is no pressure or temperature rating on the copper flex supply line that I could use as guidance.
1) Is there any rule in any plumbing code that would suggest that these "supply lines" are not to be used as "discharge lines"?
2) Is it your interpretation of the plumbing code that these lines are specifically permitted for use on the discharge line?
3) If you are a plumber, have you/would you use these "supply line" products on a water heater discharge line?
4) Have you ever seen a problem with one of these devices when used on a "discharge line" that they felt was conclusively was due to its use on a discharge line?
