The Flat Out Caravan Drink Water Hose

Especially designed for caravans, motorhomes and marine — this high end gear ticks all the boxes!

Flat Out owner Zoe explains features of and usage tips for the Flat Out Drink Wate hose.

Our potable (AS4020 rated), Australian made, lay-flat caravan, marine, and commercial hoses have abrasion resistant polyester woven jacket, polyurethane (PU) lining and brass snap-on fittings. With a 19mm diameter, our hose has high capacity and boasts a 1400 kPa pressure rating (PN14 - over 5x mains pressure). The highly durable construction of the hose  ensures a long product life and provides you with the premium connection to your drinking water supply.

Stored neatly on our Multi-Reel, these flexible hoses are exceptionally user friendly, and space saving. Connect your hose at one end, hold the Multi-Reel handle and walk away to unspool. Setup has never been this easy. As you re-wind, water remaining in your hose is forced out for drip-free, compact storage.

15m Flat Out Drink Water Hose as 2 x 7.5m on Compact Multi-Reel

This versatile caravan hose solution allows you to span a long distance by joining the two hoses together combined with the convenience of only using one shorter, faster to set up hose when the tap is close. more

Thread Converter: 3/4 inch NPT male thread to 12mm snap on brass with swivel

If your water inlet on Aussie and American RVs (and boats) looks like the one in the image, it will have a 3/4inch NPT/GHT thread which isn’t exactly the same as all other plumbing fittings in Australia.

This unit has the correct thread for your inlet and is coupled with a spiffy swivel snap on tap adaptor so you can have the ultimate smooth downward angled connection removing potential bump hazards as people walk past your van and relieving pressure on o-rings for the fittings. 

3/4inch NPT/GHT parallel male, right angle to 12mm (1/2inch) snap on quick connect male.

B.E.S.T Inline Water Filter with Brass Fittings

This is the B.E.S.T. Water Filters brand model 322HB that we buy in for your convenience. Connect it to your flat out hose and then use a short hose (e.g. P11 or P13) to connect it to your van.  We love it, not only because it's Aussie Made but because it is simply better than alternatives. more

Containing SilverSafe technology it removes taste, odours, bacteria and parasites. It has no set replacement times, and if the water slows too much, simply reverse it and flush it out, it will start working the other way.  It's compact and produces great tasting water for far longer than other similar sized models. For more information feel free to visit the BEST Water Filters website.

Why Filter My Water? 

Whilst we at Flat Out personally choose to filter all water used in our vans (pressure or tank connected); if you are tank filling it is a very, very wise thing to do.

Over time any silt or dirt particles in the water will settle and create a sediment in the bottom of your tank - which is of course almost impossible to clean! But that isn't the main reason. Council water in Australia is treated for bacteria with chlorine, but if water sits for as little as a couple of days, the chlorine will evaporate. Now if bacteria or other nasties have a chance at entering your tank (and they will because tanks need vents to fill with air as the water leaves them) you risk getting sick.  As Colin from B.E.S.T says, "It only takes one bug to ruin a whole holiday!".

We love the BEST water filters because they have so much more silver than any competitor filter, meaning the filter never goes green on the inside, nor does your tank! Fine silver particles enter your tank with the water that flows through the filter, and do not disappear like chlorine does. Silver is known for its bacteria annihilating ability, and it is also healthy for you to consume in small doses.

Plated brass Pressure stop ball-valve with fittings for B.E.S.T. Filter and tank filling

This added convenience item is excellent for tank filling with Flat Out hoses and BEST filter. 

Run the hose from the tap to your filter, replace the other filter end with this valve part and then connect a tank filling attachment. This allows you to build up pressure in your hose before filling (needed to lay it in a way to make it then flow) and then when you are finished filling you can easily switch off flow before going back to the tap.

The 3/4 BSP end fits directly into the BEST filter in the place of the existing fitting. Use a watermark approved thread sealant (such as this one), don't use thread tape or overtighten as it will void your BEST filter warranty. Save the existing fitting as a spare. The other end meets 12mm (1/2inch) snap fitting standards to fit onto any other hose snap fitting, such as our tank-filling attachment (P17) or one that you make for yourself. Here's a little video we made on how to use it.

Short Drink Water Hose: Filter-to-Van Attachment

If you use an external water filter (highly recommended), your long hose goes from tap to the filter and this short hose is used to connect the filter to your caravan/motorhome water inlet. Both options also act as a space saving drip free storage method for your filter while in transit (see third product image), and assist with easy back-flushing of the filter after use. more

These filter-to-van attachment hoses are made of the same high quality taste free hose as the rest of the Flat Out range (with the German PU liner), have the beautiful and ever-so-practical brass fittings, and take up very little room. 

Which length is best for me?

The 1.5m hose will reach from the caravan/trailer/motorhome to the ground for a high water inlet, and give you a little more freedom of where to place the filter (such as under the van). The main advantages of the 0.7m are the easier pack up and simpler back-flushing.

The bend radius of the hose is about 0.4m when under pressure, so if you wish to put your filter at a specific angle, we suggest using the swivel attachment to the van: P8 or P5. The 0.7m might need a strategically placed mounting bracket. 

$68.00 - $85.00

Please Select
Tank Filling Attachment Taste Free with Brass Fittings

25cm taste free solid hose with brass snap-on connector. This is a spout used to fill your tank when not connected via the pressure inlet. 

This is our premium grade tank filler with brass fittings for longevity (not really necessary for pressure rating with this application) and because it's so nice to match the rest of your set. 
Connect this product to your Flat Out Drink Water hose to allow easy insertion to your tank with our product P7, onto the other side of an inline filter, or any brand 12mm hose coupler.

Tomson Pressure Limiting Valve 350 KPA

Mains water pressure varies from campsite to campsite. Too much pressure is risky to caravan/RV pipes. While our hoses boast a high pressure rating, this simply means they will withstand high pressures and not break. Your Caravan might not have the same pressure capacity and so it can be wise to install a pressure limiting valve before your water inlet. 

When asked our advice, we offer this solution from Tomson. You can buy it here or at your local Reece Plumbing outlet. 

It will join inline with the BEST filter using a 3/4” Hex socket also available at Reece. Simply remove one brass end of the filter and replace with the set as shown in the photo. We also added our stop valve to this set [P20].

If you feel these items should be available directly from our store please give us this feedback and we will investigate the possibility.

End Repair Kit for Drink Water Hose
End Repair Kit for Drink Water Hose

Repair Kit: 1x replacement brass snap-fitting, 1x rubber sleeve, 1x stainless steel hose clamp

Our hoses are pretty darn hard to break, but if you're one of those people who like to be extra prepared, you can carry a repair kit to get you out of trouble should you have a problem out bush.

As Flat Out hoses have a 19mm diameter this brass hose tail is not accessible at regular hardware stores. The custom made rubber sleeve helps ensure even spread of pressure and prevents the clamp cutting through the hosing. The hose clamp is Tridon brand (Aussie Made). Once fitted correctly, the end repair kit is just as strong as the original crimped on fitting, will maintain the high pressure rating and won’t leak. more

This product is used to repair an issue such as a pinhole leak in the Flat Out Drink Water Hose that is close to an end (you will discard the off-cut). Should your issue be central in the hose, consider the Join repair kit (R7) so you can keep both ends of your hose. 

Purchase to fix an issue that has developed in your hose rather than a full replacement, or carry in advance just in case of an emergency while traveling.

B.E.S.T Inline Water Filter REPLACEMENT
B.E.S.T Inline Water Filter REPLACEMENT

Filter replacement for B.E.S.T inline filters, unscrew the brass fittings from your existing unit and use on this one when you swap them over. You will save money and also be recycling!

When do I change my filter?

Your B.E.S.T water filter is back-flushable and will not clog with dirt. The silver concentration in these units is higher than any other filter we know of and will outlast the carbon, so coupled with its 2 way feature that ensures no bacteria will grow inside the unit, you don't have a time-frame for replacement. 
Yet, as with any filter over time, the microfine carbon will eventually reach its capacity to remove the bad tasting minerals from the water. Depending on the quality of water you push through the filter, will be how long this takes. The 'rating' is 5000L but you will simply know it is time to replace your filter when the water starts to taste bad.

Blue Vs Grey - New German Hose Liner!

You will see two versions of FLat Out drink water hoses represented online and in stores. The new Electric Blue variant of the Flat Out hoses features an upgrade to our polyurethane (PU) lining material, now formulated in Germany. As German quality control standards are among the highest worldwide, this material is even lighter, more flexible and tougher than its predecessor. The Classic Grey variant was already world class, yet we are now sold out of it at Flat Out HQ. You may still find it available with our stockists around Australia during early 2024.  

"Did you know PU is such a safe and high performance material that it's used to make medical tubing?"

  • Rolls up completely flat
  • Taste Free, drink water, potable liner
  • Durable brass snap on fittings
  • 19 mm internal diameter provides high flow and no kinking
  • No need to dry
  • Dual size brass tap adaptor included
  • Australian made with 3 year warranty

Taste Free Hoses  - what does AS4020 mean?

Flat Out drink water hoses are accredited with AS4020 certification, the best rating available in Australia. The hoses are manufactured in a ISO9001 quality accredited factory and also conform to the German BGA DIN39 potability standard. 

To achieve these standards our manufacturers have worked through a long accreditation process which includes rigorous lab testing in Adealide. Please be aware there is also a drink water standard in Australia of AS2070. Hoses with that standard are simply made from food grade plastics but have not been through testing.

International Compatiblity

While Flat Out hoses are designed and made in Australia primarily for use in this country, they can be used anywhere and our international fan-base is growing. That said, the dual size tap adaptor that comes with some of our hoses is BSP threaded, and other locations use different guage (usually GHT or NPT). You should be able to purhcase compatible fittings for your location locally as the 1/2inch or 12mm snap fittings crimped to the hoses are universal. As an example, pictured here is a set of fittings that can be used in USA. These fittings were purchased at a general hardware store (in USA). If you are unsure what is needed in your location, you can email us to ask. Please give as much information as you can about the tap systems where you live and also if possible, send a photo of the water inlet on your RV.

Other Setup Tips

Excess length of hose between tap and van

  • Attach the hose to the tap, and unspool full length of hose towards your van
  • Make a coil (about 0.7m diameter) under your water inlet with the excess length
  • Connect to van water inlet
  • Turn on tap to add pressure
  • gently release any kinks that may initially form when pressurising

Connection to your caravan, camper or motorhome

Our hoses work best with a downward connection, it's not essential as the hose under pressure will simply bend widely, but it does reduce bump hazzards if there is likely to people regularly walking past the side of your van. If you have a horizontal or upward BSP inlet, we advise additional purchase of an elbow adaptor.

horizontal connections

Filling water tanks (no pressure connection)

  • Cut off approximately 30 cm from a solid drink water hose and fit a standard snap fitting (or use our product P17)
  • Use a coupler (P7 or any brand equivalent) to join the Flat Out hose and the ordinary hose, or insert your inline water filter if using.
  • Insert ordinary hose in the tank opening; you are now ready to turn on the water supply tap and quickly fill up your water tank with ease

How to pack away your flat out hose

Top 4 tips for super easy hose packup onto Multi-Reel every time:

  1. Lay the hose flat and straight before starting to wind it onto the reel. This prevents kinks and makes for a smoother, faster rollup.
  2. Give the hose a few minutes to drain any excess water.
  3. Simply spin the Multi-Reel handle when you approach a twist in the hose. This flattens the twist onto the reel, preventing it from tightening and potentially causing a snag later.
  4. While winding, apply light tension to the hose about halfway between the reel and the end you're holding. This creates a smoother, tighter coil and prevents the hose from bunching up.

How to wind up drink water hose so it fits every time

Seasoning the hose

Before using your new hose for the first time, it is a good idea to season your hose.This helps remove any potential residue left over from manufacturing. Here's how:

  1. Attach and Pressurize: Connect the hose to your outdoor tap and attach a trigger sprayer to the end. Turn on the water and pressurize the hose fully.
  2. Sun Exposure: Leave the pressurized hose in direct sunlight for a few days. Each time you walk past, simply discharge about 5 liters of water. This helps flush out any remaining debris.

Rest assured, leaving your hose in the sun won't damage it. As it is designed for continuous use and sunlight exposure.

This is what seasoning your hose looks like
