Tucson Equinox fault 6C

Air locked (pump runs but delivers no water)

Shower pump

What it means

Pump runs but delivers no water because the system is air locked.

Likely causes

  1. Air Locked
  2. Air lock in pipework
  3. Expansion and contraction of hot and cold-water pipework causing connections to work-loosen
  4. Internal component commissioning causing temporary odour
  5. Shaft seal run-in period causing moisture discharge
  6. Lime scale build-up from extended non-operation

Where to start

  1. Check for air locks, examine the pipework layout to check for high points
  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
