Reliance Products Jumbo-Tainer 2.0, 7 Gallon (8630-03)

Reliance Jumbo-Tainer 2.0 Review: A 7-Gallon Spigot Jug for Gravity-Fed Van Water

The simplest way to get running water in a van has no pump, no hose and no wiring at all: a rigid jug with a tap, sitting where a cup or a pot fits under it. The Reliance Jumbo-Tainer 2.0 is built for exactly that. It's a 7-gallon (26-litre) rigid water container with dual handles, a slim profile and what Reliance calls a "leak-proof, hideaway spigot", a tap that stores inside the cap for travel and screws into the opening when you want to dispense.

Our no-plumbing sink guide has said for a while that no spigot jug was in our catalogue. This is the one we've now checked against the maker's documentation. It fills a different slot from the Scepter 05177, which is a narrow jerrycan with a pour spout and no tap, and from the MSR Dromedary 10L, which is a soft bag for spare water.

What the Amazon link sells: the Reliance Products Jumbo Tainer 2.0, 7 Gallon, ASIN B09NP5538N, Reliance part and model number 8630-03 (Reliance's own site lists it as SKU 08630-03). It's a single container. The listing photo shows a blue body with red caps. The listing's colour field says "Red", which appears to describe the caps, so check the photo rather than the field.

This review is research-based. VanLifeKitchens doesn't test products hands-on. The specs below come from Reliance's product, care and warranty pages and from the Amazon listing we link to. Anything we've calculated, such as full weight, is labelled as our estimate.

Choose this if:

• You want water on tap by gravity, with no pump, wiring or plumbing.
• You want one larger jug rather than two 5-gallon cans, and you have the floor or low-shelf space for it.
• You want a rigid jug whose maker sells a replacement spigot, so a worn tap doesn't mean a new jug.

Skip this if:

• You can't safely lift around 60 lb. A full 7-gallon jug is heavy, and you'll need to move it to refill.
• Your only space is a narrow slot beside a fridge. At 8.5 inches wide it's slimmer than a cube jug, but it's wider and much heavier than the 6.8-inch Scepter.
• You need a published drinking-water certification such as NSF/ANSI 61. Reliance cites LFGB and FDA compliance instead (see below).

What it is and how it's used

The Jumbo-Tainer 2.0 is a one-piece rigid plastic container with two moulded handles, a main cap and, per the listing photo, a second smaller cap on the top shoulder. The spigot lives inside the main cap when you're driving. To dispense, you take the cap off, reverse the spigot and screw it into the opening.

Because the main opening sits on the top shoulder, as the listing photo shows, a fitted spigot only delivers water by gravity once the jug is turned so the spigot is at the bottom. In practice that means laying the jug on its side on a counter, shelf or the edge of a platform, with the spigot overhanging enough that a cup, kettle or pot fits under it. Reliance's product page doesn't describe the dispensing position, so check how your jug sits with the spigot fitted before you build a shelf for it.

Reliance's page lists the Jumbo-Tainer as compatible with its Replacement 70mm Spigot Assembly (SKU 7210-03R), which Reliance says fits its 70 mm opening containers made after 2015. That tells you two useful things: the opening is the 70 mm size Reliance uses across its jug range, and the tap is a replaceable part.

Specifications and sources

Full weight, our estimate. Water weighs about 8.34 lb per US gallon, so 7 gallons is about 58.4 lb, plus the 2.9 lb jug: roughly 61 lb full. That figure decides almost everything about where the jug can live in a van.

Warranty. Reliance's warranty page says its water containers carry a five-year limited warranty against defects in materials and workmanship, excluding damage from owner modification, repair attempts or improper handling and storage. The Amazon listing's warranty field says "2 year limited". Keep the receipt and check the paperwork in the box.

Drinking water: what Reliance does and doesn't claim

Reliance's product page says the Jumbo-Tainer 2.0 is "LFGB certified & FDA compliant" and cites a test report number, and describes it as PFAS and BPA free. LFGB is the German food-contact framework, and FDA compliance refers to US rules for food-contact materials. Both are about the plastic being suitable for food and drink contact.

What Reliance doesn't publish is an NSF/ANSI 61 listing, the certification plumbing components use for drinking-water contact. So the accurate statement is: the maker sells it for drinking water and cites food-contact compliance, but it isn't an NSF-listed water container.

The container also does nothing for water quality. Whatever goes in comes out. If you fill from an unknown spigot, treat the water before drinking. Our water filtration guide explains which filters handle bacteria and protozoa, which also handle viruses, and which only improve taste. A gravity jug pairs naturally with the LifeStraw Home pitcher for treated tap water: tap water out of the jug, filtered water out of the pitcher.

How it fits a van or camp kitchen

Measure for two positions. You need space for the jug standing upright to travel, and space for it on its side to dispense, unless those are the same spot. Upright it needs about 15.3 x 8.5 inches of floor and 18 inches of height. On its side, the footprint becomes one of the longer faces and the spigot needs to overhang an edge. Measure your counter, shelf or slide-out with the jug's real dimensions before you commit.

Height above the cup. Gravity flow depends on the water being above the outlet, and the outlet needs to be above whatever you're filling. Plan for a kettle or pot to fit under the spigot. Reliance doesn't publish a flow rate, so expect the stream to slow as the jug empties.

Lifting. At about 61 lb full (our estimate), lifting the jug onto a counter-height shelf is a real strain, and doing it in a moving or sloped van is how people get hurt. Two common answers:

• Dispense from low. Keep the jug on a floor-level platform or a low step with a sink or basin edge just below it, so the jug never has to go higher than you can slide it.
• Fill in place. Carry water to the jug in smaller containers, such as the MSR Dromedary 10L, rather than carrying a full 7-gallon jug to the tap.

Securing it for driving. A full jug this heavy has to be restrained. Reliance says the handle placement "allows the unit to be securely fastened down", so run a cam strap through a handle to a solid anchor, or box it into a cabinet sized to its footprint with a positive-latching door. Non-slip liner and bungees aren't restraint for a 60 lb load. The stop van kitchen rattles guide explains the difference between reducing noise and actually securing heavy items, and the storage guide covers where heavy things should live.

Travel with the spigot stowed. Put the spigot back inside the cap before you drive. A spigot left fitted is exposed to knocks and is one more seal that can weep if the jug shifts.

Not stackable full. Reliance's care page says its containers "are not stackable when full" because of the weight. Don't build a two-jug stack and hope for the best.

Care, cleaning and storage

Reliance's care page gives clear rules:

• Rinse before use and before storing, with either baking soda and water or vinegar and water, "a few times". Reliance says not to use baking soda and vinegar at the same time.
• Dry it completely before storing, to inhibit bacterial growth.
• Don't store water longer than 90 days. For emergency reserves, Reliance says to empty, clean and refill every 90 days.
• Keep it out of direct sunlight. Reliance says UV degrades plastic, and recommends a cool, dark place.
• Hand-wash the spigot cap. Reliance says not to put it in the dishwasher.
• Fill only with water-based substances.

Reaching inside. A 70 mm opening is too small for most adult hands, so you won't scrub the inside walls by hand. Plan on a long-handled bottle brush and the rinse-and-shake routine Reliance describes. The no-plumbing sink guide explains why cleaning access is one of the three things that decide which jug works, and walks through sanitising a fresh jug.

Freezing. Water expands as it freezes and stresses any rigid container, its seals and the spigot. Reliance's pages don't publish a freezing rule. In freezing weather, keep the jug inside the heated part of the van, or empty it. Our winter van kitchen guide covers cold-weather water in more detail.

Limitations

• Heavy when full. About 61 lb by our estimate. This is the main reason to choose two smaller cans instead.
• Dispensing needs the jug on its side. Plan the shelf around that, not just around the upright footprint.
• No published flow rate and no hose port for a pump. It's a gravity jug. If you want a pump, the narrow Scepter 05177 with a Whale Babyfoot intake through the cap is the more common pairing.
• No NSF/ANSI 61 listing. Reliance cites LFGB and FDA food-contact compliance instead.
• 90-day storage limit in Reliance's care guidance, so it isn't a fill-and-forget reserve.
• Warranty figures differ between Reliance's site and the listing.

How it compares on this site

The Scepter is the better choice when space is narrow, you want to lift less per container, or you're building around a foot pump. The Jumbo-Tainer is the better choice when you want water from a tap with nothing else to buy. Our Jumbo-Tainer vs Scepter comparison sets the two side by side.

If you're moving to a plumbed system later, the jug doesn't go to waste. It works as a refill carrier for a fixed tank, or as a backup water supply if a 12V pump such as the SHURflo Revolution 4008 fails. The van water system setup guide covers fixed tanks and pumps.

Which guides it fits

• No-plumbing van sink setup: the "jug with a built-in spigot" option for dispensing by gravity.
• Water filtration complete guide: what to pair with it for drinking water.
• Van dishwashing system: a spigot jug and a basin cover the low-water wash routine.
• Storage complete guide: heavy items go low and get restrained.

Verdict

The Reliance Jumbo-Tainer 2.0 is the straightforward way to get running water in a van without a pump: a 7-gallon rigid jug with a tap that stows inside the cap, a 70 mm opening that takes a replaceable Reliance spigot, and handles placed for strapping down. Reliance publishes its dimensions, empty weight, food-contact compliance, care rules and a five-year container warranty. Its limits are the ones any big jug has: about 61 lb full by our estimate, no NSF/ANSI 61 listing, and dispensing that only works with the jug on its side. Plan the shelf and the restraint before you buy, and it's a simple, low-maintenance water supply.

FAQ

Does the Reliance Jumbo-Tainer 2.0 come with a spigot? Yes. Reliance describes a "leak-proof, hideaway spigot" that stores inside the cap and is fitted into the opening for dispensing. Reliance also sells a replacement 70 mm spigot assembly that it lists as compatible with the Jumbo-Tainer.

How much does a full Jumbo-Tainer weigh? Reliance lists the empty jug at 2.9 lb. Seven US gallons of water weigh about 58 lb, so a full jug is roughly 61 lb by our estimate.

Will it fit in a van cabinet? Reliance lists it at 15.3 x 8.5 x 18.0 inches. That fits many sink cabinets upright, but you also need space to lay it on its side with the spigot over an edge if you dispense from it in place. Measure both positions.

Is it safe for drinking water? Reliance sells it for drinking water and says it is LFGB certified, FDA compliant and free of PFAS and BPA. It doesn't publish an NSF/ANSI 61 listing. The jug doesn't treat water, so filter or purify anything from a questionable source.

How long can water be stored in it? Reliance's care guidance says not to store water for more than 90 days, and to empty, clean and refill it every 90 days for emergency reserves.

Can two full jugs be stacked? No. Reliance says its containers are not stackable when full because of the weight.

How should it be cleaned? Reliance recommends rinsing a few times with baking soda and water, or vinegar and water (not both together), then drying it completely before storage. Hand-wash the spigot cap. A bottle brush helps, since the 70 mm opening is small for a hand.
