For obvious reasons the system appears to be under unnecessary surges and stresses. Did you advise the JP be set per #20? Hopefully it's not 'another' installation where the JP doesn't match the FP. TD
I was at a location yesterday where they have had a problem of splits in CPVC pipe in a basement. The fire pump churn is roughly 175 psi but the jockey pump is set at 150 psi. Would repeated water hammer from weekly/quarterly/annual tests create enough fatigue to cause failure? Todd G.
