Details

Nuova Simonelli No-Return Check Valve Spring

The spring from inside the no-return check valve on Nuova Simonelli machines, keeps hot water from backing up through the check valve between brew cycles.

COMPATIBILITY

  • Fits: Nuova Simonelli no-return check valve assemblies
  • Replaces: Nuova Simonelli S_94, superseded by S_457

INSTALLATION

Requires disassembling the check valve, best handled by a technician.

PRO TIPS

  • A tired check valve spring is a common, overlooked cause of inconsistent brew pressure at the start of a shot, if your pressure gauge takes a moment to climb to target, this spring (not the pump) is worth checking first.
