Rebuild Steps

The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.

  • Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.
  • In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.
  • Complete Disassembly: The unit is disassembled and all parts are laid out for individual inspection.
  • Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.

Diagnostic Testing

Each BOSCH 0811-404-498 is tested on a dedicated flow bench before it ships. We check pressure, flow, leakage, and response characteristics against published specifications. Our performance testing verifies consistent performance.
