Tucson Equinox fault 2.C

Flow rate too high (water's velocity)

Shower pump

What it means

Noise in the system caused by excessive water velocity due to flow rate being too high for the pipe sizing.

Likely causes

  1. Flow rate too high (water's velocity)
  2. Expansion and contraction of hot and cold-water pipework causing connections to work-loosen
  3. Internal component commissioning causing temporary odour
  4. Shaft seal run-in period causing moisture discharge
  5. Lime scale build-up from extended non-operation

Where to start

  1. Check pump head selection and pipework diameter
  2. Retighten connections that may have work-loosened during initial weeks/months of operation
  3. Check for small discharge of moisture from shaft seal during run-in period
