Frequently Asked Questions
Q: What does the Whale Superfil pump kit do?
If you have a Whale Easi-Slide socket with a 12V connection, the Superfil kit lets you pump water into your onboard tank from an external container such as an Aquaroll or jerry can - so running out of water doesn't mean packing up to drive to the nearest tap.
Q: Which is better - a submersible pump or a pressure pump?
It depends what you need. Whale's submersible pumps are simple, compact, quiet and inexpensive, and come in three flow rates: standard (10.3 litres/min), premium (13.2 litres/min) and high (15.8 litres/min). The Watermaster Onboard pressure pump (8 litres/min) is fitted inside the vehicle and gives a smooth, steady flow; it has its own built-in pressure switch, can run dry without damage, and is built to last.
Q: Is a submersible pump quieter than a pressure pump?
Yes. A submersible pump is a centrifugal design with an impeller as its only moving part, so it runs very quietly. A pressure pump is simple to fit and very dependable, but it's noisier.
Q: When would I need a pressure switch or a surge damper?
A Whale pressure switch is for vehicles fitted with a submersible pump: it senses the drop in water pressure when a tap is opened and turns the pump on. Because it works with any tap, you aren't restricted to taps with built-in microswitches.
