New Electric Rheem water heater installed in basement of 80 year old home.
TPR discharge tube rises approximately 3 feet and then goes horizontal to outside.
Strange spiraling small diameter copper piping tapped into the TPR discharge tube. looks like the piping for an ice maker in a refrigerator but it is tapped into the TPR discharge tube where there is no water. This small diameter tube is kinked and pinched off at the end.
Only thing I can think of is that this is to allow
A. overflow of the discharge tube downward? B. draft air in the discharge tube to allowthe water to rise upward? C. just plain wrong
What is your opinion? I’m going with ‘C’ until I hear otherwise.
