When John, a homeowner on Springfield Court, Noble Park, VIC 3175, called about low hot water pressure and lukewarm water, he thought his Rheem 170L system was simply failing. Our expert plumber quickly diagnosed the root cause: two critically aged external valves that were 20 years old and had compromised the unit’s operation and safety.

The Expert Diagnosis: Multi-Point Valve Failure

The heating unit itself was functioning perfectly, as it had only been installed four years prior. Our plumber began by checking the unit’s core component, the Rheem Gas Hot Water Eurosit 630 gas control valve, to ensure it was firing up properly on a higher thermostat setting. This confirmed the heating unit was functional. The problem lay entirely in the external plumbing. Our plumber performed a specialized diagnostic sequence:

  1. Tank Temperature Check: The plumber performed a PTR valve touch test on the relief pipe, confirming the water temperature inside the tank was hot.
  2. Aged Valve Failure: The two crucial external valves—the 15mm RMC Duo Valve and the Temperature Control Valve—were the original fittings from when the house was built 20 years ago. Both were faulty due to age. The failed Duo Valve caused the low pressure and flow issues, while the failed Temp Valve mixed in excessive cold water.

The critical insight for John was that the general contractor who installed his unit four years ago had failed to replace these aged, essential external valves—a basic compliance oversight.

The Solution: Compliant Restoration of Hot Water Delivery

The comprehensive repair required replacing both failed external components. Our plumber sourced a new Thomson Quarter-Turn Duo Valve and a new Thomson 15mm Temperature Control Valve from Reece Plumbing in Clayton.

The final commission involved installing the new valves and ensuring:

  • The new valves restored full pressure and flow.
  • The new Temperature Control Valve was strictly calibrated to deliver hot water at less than 50 Deg. Celsius, ensuring compliance with mandatory safety regulations.
