Bailey Water System (2013 Model Year, Unicorn / Pegasus)
Sourced from Bailey's 2013 model year owner's manual for the Unicorn / Pegasus range. If your caravan is a different age or range, some details — such as the exact control panel brand or chassis-component generation actually fitted — may not match. Always cross-check against the handbook that came with your specific caravan.

Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
N/A | Unicorn water system: pump doesn't run Possible Cause: No power to pump, or a blown fuse, or a blockage in the pipework. | Check power supply and clean/attach leads and connections. Replace the fuse (do not exceed the recommended fuse size). Check pipework for kinks. | DIY Safe |
N/A | Unicorn water system: pump runs but no water appears Possible Cause: No water getting to the pump — water tank empty, filter blocked, air leak in the pipework, or a valve lever needing adjustment. | Check the water tank is not empty and the filter is not blocked. Remove each valve lever, tighten the nut located below it and replace the lever. Check all connections from tank to pump inlet are secure — to test for air leaks, hold the showerhead underwater and operate the pump; bubbles indicate a leak. | DIY Safe |
N/A | Unicorn water system: water leaking at the outlet side of the pump Possible Cause: Loose or damaged pipework/fittings. | Check pipework and fittings for leaks and repair. Check the water system drain plugs are closed. | DIY Safe |
N/A | Unicorn water system: pump runs but will not switch off Possible Cause: Water leaking at the outlet side of the pump. | Check the water system drain plugs are closed. | DIY Safe |
N/A | Unicorn water system: no water Possible Cause: Water supply level too low, or a clogged filter. | Check the water supply level. Check and replace the filter if clogged. | DIY Safe |
N/A | Unicorn water system: pump cycles on and off periodically when all taps are closed Possible Cause: Water leaking at the outlet side of the pump (a partially opened tap causing this is normal, not a fault). | Check pipework and fittings for leaks and repair. Check the system drain plugs are closed. | DIY Safe |
N/A | Unicorn water system: pump cycles on and off excessively when taps are open Possible Cause: Excessive back pressure from kinked pipework or blocked filters. | Check pipework for kinks and ensure filters are clear. Check the shower rose/taps for blockages and repair. | DIY Safe |
N/A | Unicorn water system: noisy operation Possible Cause: The pump is drawing air, is not secured to a solid surface, or the pipework is not securely supported. | See the remedy for 'no water getting to the pump' if the pump is drawing air. Otherwise, check the pump is secured to a solid surface, clear of hard surfaces, located away from interfering surfaces, and that pipework is securely supported. | DIY Safe |
N/A | Unicorn water system: low flow Possible Cause: Pipework/connections too small or crushed by over-tightened jubilee clips, a discharged battery, a clogged pump internal filter, or water leaking at the pump outlet. | Check for kinks/blockages in pipework and that connections are the correct bore. Check the battery is not discharged. Replace any damaged connections. If the pump's internal filter is clogged, remove the fitting connected to the pump inlet, use point-nosed pliers to remove the cylindrical filter mesh, clean and refit. | DIY Safe |
N/A | Pegasus GT65 water system: the pump will not run | Check the contacts in the plug and socket are clean and making contact. Check the wiring connections. | DIY Safe |
N/A | Pegasus GT65 water system: the pump motor runs steadily and will not stop Possible Cause: No water in the container, or battery voltage too low (at or below 10.5 volts). | Check there is water in the container. Adjust the switch and/or recharge the battery if voltage is low. Check all connections in the pipework. | DIY Safe |
