Why is the flow reduced or intermittent in my Stuart Turner Water Pump?
- M
  mrobinsonAug 19, 2025
  If your Stuart Turner Water Pump is delivering reduced or intermittent flow, several factors could be the cause. Start by ensuring the installation complies with the provided instructions, paying special attention to the anti-aeration flange. Verify the pipe sizes are correct. Clean the inlet filters. Ensure that the hot water temperature isn't set too high by reducing the cylinder thermostat setting to a maximum of 60 degrees Celsius. Finally, check the shower head spray plate for blockages and clean it according to the manufacturer's instructions.

How to troubleshoot a Stuart Turner Monsoon U1.5 bar Twin Water Pump that will not start?
- J
  Johnathan CraigAug 22, 2025
  If your Stuart Turner Water Pump won't start, begin by checking the electrical supply to ensure it's functioning correctly. If the motor 'buzzes', immediately switch off the power and contact Stuart Turner. A damaged pressure switch could also be the problem; turn off the power, release system water pressure, and then turn the power back on to see if the pump starts. If it doesn't, contact Stuart Turner. Lastly, make sure the recommended static inlet/outlet heads aren't exceeded by repositioning the pump.

What to do if Stuart Turner Monsoon U1.5 bar Twin runs on when all terminal outlets are closed?
- D
  Debbie StoneAug 26, 2025
  If your Stuart Turner Water Pump continues to run even when all outlets are closed, there could be several reasons. First, check for any leaks in the system, including tap washers, toilet valve washers, and pipe joints. Ensure the reed clamp is correctly fitted in the location groove. If the pump still runs, it indicates a closed circuit in either the flow switch reed, pressure switch, or PCB in the terminal box; these should be checked electrically. You can isolate the pump electrically and hydraulically and remove the brass housing that contains the float to check the float for free movement.

Why does my Stuart Turner Monsoon U1.5 bar Twin Water Pump start when outlets are off, or cycle (hunt) on/off frequently?
- J
  Janice HamiltonAug 28, 2025
  If your Stuart Turner Water Pump starts when outlets are off or cycles frequently, it could be due to a leak in the system. Check tap washers, toilet valve washers, and pipe joints for leaks. Additionally, low pre-charge pressure in the pressure vessel could be the cause. Check the pre-charge pressure in the pressure vessel. Debris under the non-return valve sealing face may also cause this issue. Try running the pump at full flow to flush away debris, or remove, clean, or replace the non-return valve.

How to fix Stuart Turner Monsoon U1.5 bar Twin that will not start?

  Keith HermanAug 31, 2025
  If your Stuart Turner Water Pump won't start, begin by checking the electrical supply, ensuring all wiring connections are secure and all switches are 'on'. Inspect the fuse and circuit breaker. If these are fine, turn off the power, release system water pressure, and then turn the power back on. If the pump still doesn't start, it could be due to a faulty pressure switch, reed switch, or PCB. Also, the internal motor thermotrip may have activated; in this case, wait for it to auto-reset and verify that the duty point and run time are within specification. If NOT refer to circuit test in Fig. 17 to confirm PCB operating correctly. Also re-position pump if needed.

What to do if there is no hot water with my Stuart Turner Monsoon U1.5 bar Twin Water Pump?
- D
  Donald HallSep 3, 2025
  If you have no hot water when using a Stuart Turner Water Pump, several factors could be responsible. Start by checking if the hot water pump has an air lock and vent it to remove any trapped air. Ensure the heat source, like the boiler, is switched on. Verify that the hot water cylinder contains hot water. Lastly, a faulty thermostatic mixer valve might be the cause; in this case, consult the manufacturer's instructions for the valve.

What causes flexible hose leaks in a Stuart Turner Monsoon U1.5 bar Twin Water Pump?
- M
  Mason WalterSep 6, 2025
  To address flexible hose leaks in your Stuart Turner Water Pump, first, check that the hose is firmly pushed onto the pump's inlet/outlet connections and pipework to ensure correct fitting. Also, inspect the 'O'-rings for damage and ensure copper pipe ends are cleanly cut and deburred.

Why is there no hot water with my Stuart Turner Water Pump?

  Kristin BrownSep 9, 2025
  If you have no hot water when using your Stuart Turner Water Pump, it could be due to several reasons. The water feed might be air-locked, so vent the hot water pump to remove any air. Check the cold feed to the hot water cylinder, ensuring the water level in the cold water tank is adequate and that all stopcocks and isolating valves are open. Also, make sure the boiler is switched 'on', check the cylinder thermostat and immersion heater, and verify that the cylinder contains hot water and that the tank volume is adequate. Consult makers instructions.

What causes reduced flow/performance in a Stuart Turner Monsoon U1.5 bar Twin?
- J
  Jose QuinnSep 12, 2025
  Reduced flow or performance in your Stuart Turner Water Pump can be attributed to a few common issues. Check for blocked inlet strainers and clean them. Also, inspect the shower head spray plate for blockages and clean it. Blocked pipework or the pump itself can also restrict flow. Isolate the pump electrically and hydraulically, then locate and remove any blockages.

Why does my Stuart Turner Monsoon U1.5 bar Twin Water Pump keep running or cycling on and off?
- D
  David BradleyNov 15, 2025
  If your Stuart Turner Water Pump runs continuously even when outlets are closed, or if it frequently cycles on and off, the issue could stem from several causes. First, check for leaks in your system by inspecting tap washers, toilet valve washers, and pipe joints. If the pump persists in running, it may indicate a closed circuit in the flow switch reed, pressure switch, or PCB within the terminal box, in which case you should contact Stuart Turner. Another potential cause is a jammed flow switch, which can be resolved by removing outlet hoses and ensuring the flow switch is in its lowest position. Additionally, inspect the pressure in the pressure vessel. Debris under the non-return valve sealing face could also be the culprit; try running the pump at full flow to flush away any debris, o...
