Oorzaak: Normal operation during water heating in storage tank

This is expected behavior. The valve will discharge approximately 3% of the storage capacity during the heating period.

Oorzaak: Build up of foreign matter in the valve

Gently raise the easing lever on the PTR Valve for a few seconds, then release gently to dislodge any particles.

Oorzaak: Excessive water supply pressure, faulty PTR Valve, or faulty thermostat

Turn off electricity supply and water, then contact your Dux agent for service.

Oorzaak: PTR Valve discharging too much water, incorrect water heater size, excessive hot water usage, longer heating time during night, underestimated usage patterns, or leaking taps/pipes

Check PTR Valve operation, verify heater size matches requirements, review family hot water usage patterns, check shower flow rates, consider installing flow control valve, allow longer heating time at night, inspect tap washers and pipes for leaks and replace if necessary.

Oorzaak: PTR Valve discharging too much water, excessive hot water usage, or leaking hot water pipes/taps

Check PTR Valve discharge, review outlet hot water usage, inspect for leaking pipes or dripping taps, replace faulty tap washers, and have plumber repair any leaking pipework.
