Soft patches are used for repairing small holes in piping and have a rupture rating of up to what psi?

• A. 200 psi
• B. 100 psi
• C. 150 psi or less
• D. 300 psi

Answer: (C)

Soft patches are a temporary, low-pressure repair for small holes in piping. The important limit is the rupture rating—the maximum pressure the patch can safely withstand without bursting. For soft patches, that ceiling is 150 psi or less. So the maximum safe pressure you can run through a system with a soft patch is 150 psi, which is why this option fits best. If the system operates above that, a soft patch isn’t reliable and a more robust repair method is required.
