Questions about this item
How often should the cast copper union be inspected or replaced in a typical plumbing system?
Cast copper fittings do not have a scheduled replacement interval; inspect joints during routine system checks and replace only if corrosion, leakage or mechanical damage appears.
What is the first limit reached when the fitting operates continuously at high temperature and pressure?
The pressure rating of 408 psi at 100 °F is the governing limit; sustained exposure above that pressure or beyond the 400 °F temperature ceiling will cause failure first.
