The Best Caravan Water Hoses

Your caravan water hose does two jobs: filling your tanks at water stations and connecting to town water at caravan parks. Both require a food-grade hose. Not a garden hose, not a general-purpose hose, a proper drinking water hose designed specifically for potable water. The difference matters more than you’d think, especially when you’re filling your tanks in 40-degree heat and drinking that water for the next week.

This guide covers the best water hoses for caravanning, the fittings and adapters you’ll need, and how to keep your water system clean and functional on the road.

Why Food-Grade Matters

Standard garden hoses are made with PVC that contains plasticisers, lead, and other chemicals you wouldn’t want anywhere near your drinking water. When water sits in a garden hose in the sun (which it will, constantly), those chemicals leach into the water. You can taste it, and the long-term health implications of drinking plasticiser-laced water for months on end aren’t great.

Food-grade hoses are manufactured from materials approved for contact with drinking water, typically reinforced PVC or polyurethane that’s free from lead, BPA, and phthalates. They won’t taint the taste of your water even after sitting in direct sun. Look for hoses labelled “drinking water safe,” “food grade,” or “AS/NZS 4020 approved” (the Australian standard for products in contact with drinking water).

What To Look For

Length: 20 metres is the standard recommendation. It’s long enough to reach most caravan park taps and water fill stations. Some travellers also carry a shorter 10-metre hose for quick tank fills where the tap is close, which saves unwinding the full length for a five-minute fill.

Hose type: You’ll choose between flat (lay-flat) hoses and round (traditional) hoses. Flat hoses roll up compact and store easily, which is a big advantage in a caravan. Round hoses are more robust, less prone to kinking, and handle higher pressure better. Both work; it comes down to whether you prioritise storage space or durability.

Diameter: Standard caravan water hoses are 12mm (1/2 inch) internal diameter. This is the most common fitting size and flows fast enough to fill a 200-litre tank in 10 to 15 minutes. Larger diameter hoses (19mm/3/4 inch) fill faster but are bulkier and heavier.

Fittings: Most hoses come with standard click-on (Gardena-style) fittings. Make sure they’re brass or quality plastic. The cheapest plastic fittings crack in UV and cold, and a failed fitting at a water station in the middle of nowhere is a frustrating problem. Carry spares regardless.

The Best Caravan Water Hoses

Camec Drinking Water Hose (20m, flat)

The Camec flat hose is one of the most popular choices among Big Lappers, and for good reason. It’s AS/NZS 4020 certified, rolls up to roughly the size of a dinner plate, and stores easily in a small bag or bucket. The flat design means it takes up a fraction of the space of a round hose. It handles standard caravan park pressure well, though it can kink more easily than round hoses at sharp bends. The fittings are decent quality. Around $50 to $70 for the 20m version.

Holman 12mm Drinking Water Hose (20m, round)

If you prefer a traditional round hose, the Holman drinking water hose is a solid, widely available option. It’s food-grade certified, kink-resistant, and more robust than flat alternatives. The trade-off is storage: a 20m round hose takes up more space and is heavier when full. Available at Bunnings and most hardware stores, which is handy for replacements on the road. Around $45 to $65.

Companion Food Grade Flat Hose (20m)

Available through Anaconda, this is another well-regarded flat hose option. Similar performance to the Camec at a similar price point. It comes with brass fittings (a step up from the plastic fittings on some competing models) and rolls up compact. Around $55 to $75.

Coast to Coast Drinking Water Hose (20m, flat)

A budget-friendly flat hose available through Caravan RV Camping and most caravan accessory shops. It does the job for the price, though the fittings are a step below the Camec and Companion options. A decent starter hose or backup. Around $35 to $50.

Essential Fittings & Adapters

Universal tap adapter: The single most useful fitting you’ll carry. Water taps across Australia come in a baffling variety of styles, from standard outdoor garden taps to square-shaft taps, lever taps, and taps with no thread at all. A universal adapter (sometimes called a multi-fit or snap-on adapter) handles most of them. Brands like Holman and Pope make good ones. Around $15 to $25.

Spare click-on fittings: Carry at least two spare click-on connectors and a spare hose end fitting. These are the most common failure point, and they’re the last thing you want to be hunting for in a small town on a Sunday. A $5 fitting can save a lot of frustration.

Hose reel or storage bag: A dedicated storage bag or small bucket for your drinking water hose keeps it clean, separate from non-potable hoses, and contained during travel. Some travellers use a small hose reel mounted inside the tunnel boot.

Pressure regulator: If you’re connecting to town water at caravan parks (as opposed to just filling your tanks), a pressure regulator protects your caravan’s plumbing from high water pressure. Some parks run at pressures that can damage caravan fittings and hoses over time.

Hose Care & Hygiene

A few simple habits keep your drinking water hose clean and your water tasting fresh. Drain the hose after every use rather than leaving water sitting in it. Store it out of direct sunlight when possible; UV degrades even food-grade materials over time. Give it a flush before the first use of the season and periodically during long trips by running water through for a minute before filling your tanks.

If your water starts tasting off, the hose is the first suspect. A soak in a diluted white vinegar solution (one part vinegar to ten parts water) overnight, followed by a thorough rinse, usually sorts it out. If that doesn’t fix it, the issue is likely in your tanks rather than the hose.
