Whale Smartflo Pump UV0814 Problems

Whale water pumps, specifically the Whale Smart Flo uv 0814, have become a staple in many caravans. As with most mechanical devices, they can sometimes run into issues. The most vexing of all is when the pump seems to be running, but no water flows from the tap. Let’s explore this conundrum and find potential solutions.

1. The Issue at Hand

Users often find that, despite the pump operating, there is no water output. Instead, only a slight gurgling sound can be heard. This can be especially frustrating when the problem persists even after replacing parts of the pump, like the head.

2. Preliminary Checks

Before delving into technical troubleshooting, ensure:

• The internal tank has water.
• The water pump switch, if it has multiple positions (like Int on, off, Ext on), is set to the correct option.

3. Insights & Solutions

• Air Blockage: If you can feel air being pumped when lightly pressing on the tap, it’s an indicator that air might be blocking the system. One suggested remedy is to hold a container above the outside connector to prime the pump.
• Pump Whirring Before Tap Lift: If the pump starts even before lifting the tap, it could indicate an absence of water inside the new head where there might be an internal switch.
• The O-Ring Dilemma: A common culprit, as identified by several users, is the O-ring on the connector. A faulty or improperly sized O-ring can allow air to get sucked into the system. Replacing it with a suitable one can resolve the issue. It’s important to ensure the O-ring fits perfectly to prevent air intake.
• Pump Pulsing: Some users noted an annoying pulsing sound from the pump at intervals. This could potentially stem from the same air-intake problem caused by a defective O-ring.
• Strainer Attachment with New Pumps: Newer versions of the pump come with a clear strainer. It’s crucial to observe if this strainer fills with water when the pump is running. Also, take note: when using the pump from an inboard supply with the older model, it might not pass through a filter. However, the new pump design includes a strainer, which might not be compatible when on a fully serviced site.

4. Financial Considerations

It’s worth noting that while branded spare parts might sometimes seem expensive, it’s crucial to ensure compatibility and functionality. However, always compare prices from different suppliers before making a purchase. For instance, the heater dump valve, which is available online for £29.75, can cost up to £47 from certain manufacturers. Similarly, the new pump might be priced at £89 online but could go up to £129 from some dealers.

5. Conclusion

The intricacies of the Whale Smart Flo water pump system can sometimes lead to frustrating problems. However, understanding the potential issues and their remedies can save both time and money. Always remember to start with simple checks and work methodically to diagnose the problem. And, of course, community knowledge and shared experiences can often shine a light on even the most perplexing issues.
