The Whale Water Filter with Easi-Press Plug UH0042 is a caravan and motorhome external water connection with a silverised carbon filter, designed for Truma Ultraflow sockets and onboard pump systems to reduce unpleasant tastes and odours from your freshwater supply.
Designed to improve the quality of water supplied to your caravan or motorhome, this genuine Whale filter assembly provides a convenient connection between an external freshwater container and your vehicle’s existing onboard pump system. Its integrated filtration helps make water more pleasant for drinking, preparing food and everyday washing.
At the heart of the assembly is a silverised carbon water filter, designed to reduce unwanted tastes and smells commonly associated with stored freshwater. The filter has a maximum treatment capacity of 3,000 litres, providing effective filtration when maintained and replaced according to Whale’s recommendations.
The Whale Easi-Press connection system allows the plug to connect securely to compatible Truma Ultraflow water inlet sockets. Its convenient release mechanism makes connecting and disconnecting the external water supply straightforward when setting up or packing away your caravan.
Unlike external submersible pump assemblies, the UH0042 is specifically designed for water systems featuring an onboard pump. Water is drawn from the external container through the hose and filter assembly by the vehicle’s existing internal pump, making it suitable for correctly configured onboard water installations.
The filter features a simple twist-change design, allowing the cartridge to be removed and replaced without complicated tools or disassembly. Whale recommends replacing the filter after 30 days of use or 3,000 litres of water, whichever comes first, to maintain water quality and avoid unnecessary restrictions to water flow.
A particularly useful feature is the integrated hose holder, which helps keep the hose connection clear of the ground when refilling your external water container. This helps reduce contact with dirt and debris around the campsite.
The assembly also includes a protective plug cover, designed to shield the connection seals during storage and help prevent the O-rings from drying out. This provides additional protection when the water connection is disconnected between trips.
Manufactured using durable materials, including a PVC hose, ABS connection housing and carbon filtration components, the Whale UH0042 is designed for regular caravan and motorhome use.
