Universal RV Campervan Water Tank Backfill System

Universal Water Tank Backfill System for Campervans & RVs
Keep your onboard water supply topped up quickly and efficiently with this universal-fit water tank backfill system for campervans, motorhomes, racevans and RVs. Designed to integrate with existing plumbing, it allows you to refill your fresh water tank using a standard Hozelock-style hose connection, without cutting large holes in the side of your vehicle.

The system is built around a robust aluminium mounting bracket that can be trimmed to suit different vans and mounting positions. This flexibility makes it suitable for new conversions as well as retrofits on existing builds. A heavy-duty hand valve provides positive on/off control of water flow, while the included 1/2" quick-connect hose adapter links directly to your 1/2" water pipe from the tank. The components are designed for straightforward assembly: the valve is mounted through the aluminium bracket, the quick-connect adapter is screwed onto the valve thread, and your 1/2" hose simply pushes into the connector to complete the installation.

Once fitted, you can connect an external water hose via a standard Hozelock-style fitting and backfill your tank from outside the vehicle. The same setup can also be used as a convenient outlet, allowing you to empty the tank when required or supply water to compatible jet wash equipment, provided your washer can draw from a static tank. This dual function reduces the need for additional fittings or separate drain taps and helps keep your conversion layout clean and efficient.

FAQ

Q: Will this fit my specific campervan or motorhome?
A: The bracket and connection system are designed to be universal. The aluminium bracket can be trimmed to size and positioned where suitable on most campervans, motorhomes, racevans and RVs that use 1/2" water pipework.

Q: Do I need to cut a large filler hole in the side of my van?
A: No. This system is designed to be mounted on an existing panel or bracket location, allowing you to avoid cutting a traditional large sidewall filler point in many installations.

Q: Can I retrofit this to an existing conversion?
A: Yes. It can be installed on both new builds and existing conversions, provided you can access the tank feed line and mount the bracket securely.

Q: What hose connection does it use?
A: The system is compatible with a standard Hozelock-style garden hose fitting, making it easy to connect at most campsites and service areas.

Q: Can it be used with a jet wash?
A: Yes, as long as your jet wash is capable of drawing water from a static tank, the backfill system can be used as a supply point, turning your onboard tank into a practical wash source.
