Whale Caravan Water Pump Problems

The Whale water pump is a popular choice among caravan owners for its reliability and efficient water supply. However, as with any system, some issues can arise over time. A common concern noted by users is a “jerky” or pulsing noise when the tap is turned off. Let’s delve into the potential causes and solutions for this particular problem.

1. The Problem:

Upon turning off the tap, the water pump makes a recurring jerky or pulsing sound every few seconds. Despite certain efforts, such as replacing the Whale Watermaster inlet socket with an integrated pressure switch, the problem persists.

2. Potential Causes:

• Pressure Switch Setting: The pressurized system might not be set correctly, causing the pump to behave erratically.
• Water Leakage: If there’s a slight water leak, the system might be re-pressurizing, leading to the jerky noise.
• Faulty Non-Return Valve: The non-return valve in the cold inlet to the hot water tank may be malfunctioning.
• Drainage Plug Issues: The drainage plug on the water heater outside might have a worn-out washer, allowing water to escape and prompting the system to recharge.

Solutions and Remedies:

1. Adjusting the Pressure Switch: According to Whale, a short pulsing noise when the tap is turned off can be normal. However, if it persists, the pressure might not be optimal. Adjust the switch to achieve the right balance.
2. Check for Water Leaks: A water leak can cause the system to keep re-pressurizing. Ensure all connections are secure and inspect the system for any signs of leakage.
3. Replace the Non-Return Valve: Some users have found relief by replacing the non-return valve in the cold inlet to the hot water tank. This valve ensures water flows in only one direction, and a faulty valve can cause irregularities in pressure.
4. Re-set the Pressurized System: To re-set a pressurized system, turn down the knob to the bottom after filling up as usual, in a clockwise direction. Switch on the pump and open a cold tap nearby. Very slowly open the switch counter-clockwise until a good flow of cold water is achieved and the switch starts clicking. Close the tap. The system’s green light should go off and only come on when a tap is opened. After closing the tap, the clicking should cease within a few seconds.
5. Inspect the Drainage Plug: Ensure the drainage plug on the water heater outside is in good condition. If the washer on the plug is worn out, water may escape, triggering the system to recharge. Consider replacing the washer or the plug if wear is evident.

Conclusion:

Whale water pumps are a trusted choice for many caravan owners, but like any system, they can encounter issues. Being aware of the common problems and their solutions ensures that users can address concerns promptly, ensuring a seamless and enjoyable caravan experience. If problems persist, it’s always advisable to consult with a professional or the manufacturer.
