How To Store Rain Barrels In Winter
By the time the first hard freeze shows up, rain barrels stop being “set it and forget it” and become one of those things that can crack, leak, and turn into a spring headache if you ignore them. I’ve seen plenty of barrels survive winter just fine, and I’ve also seen a few split right down the seam because someone figured “it’s empty, so it’s safe.” Empty is good. Properly emptied is better.
The goal isn’t just to protect the barrel itself. It’s also to keep the spigots, fittings, and overflow lines from freezing into a mess you have to repair when you’d rather be planting tomatoes.
What Actually Needs To Happen Before Freezing Weather
The most important thing is to get the water out before repeated freezing starts. A light overnight frost isn’t usually the problem. The real damage comes when water sits in the barrel, fitting, or hose and expands hard enough to crack plastic or split a valve.
A good rule of thumb: once nighttime temperatures are regularly dropping below freezing, don’t wait for a perfect weekend. Drain it, disconnect it, and decide where it’s spending winter.
Quick winter prep checklist
- Drain the barrel completely
- Disconnect the downspout diverter or inlet
- Remove or open the spigot so trapped water can escape
- Clean out leaves, silt, and algae on the inside
- Store lids, screens, and small parts together
- Protect the barrel body from cracking or UV damage
Should You Store It Indoors Or Leave It Outside?
This is where people overcomplicate things. If you have the space, indoors is easiest. A garage, shed, basement, or covered porch keeps the barrel out of ice, snow load, and direct sun. If the barrel is a lighter plastic model, moving it inside is usually the safest option.
If you can’t move it, outside storage can still work fine as long as it’s fully drained and disconnected. An empty barrel sitting upright outside is not automatically a problem. What matters is whether it can collect water again through a loose fitting, open inlet, or a cracked lid.
If you store a barrel outdoors, make sure it can’t become a little frozen pond again. Most winter damage starts with water sneaking back in after the first drain.
When outdoor storage is fine
Outdoor storage is usually not a big deal if the barrel is:
- completely empty
- disconnected from the roof system
- not holding water in the spigot or hose threads
- set where snowmelt won’t refill it
That said, I would not leave a barrel with fragile fittings exposed to repeated freeze-thaw cycles if there’s an easy indoor spot available. The barrel body may survive, but the cheap plastic valve often won’t.
How To Drain It Without Missing The Hidden Water
This is where a lot of people make the common mistake of thinking “I tipped it and nothing came out, so I’m done.” Not quite. Rain barrels hold water in places you don’t immediately notice: the bottom lip, threaded outlets, hose bibs, screened inlets, and any attached overflow hose.
Here’s the practical way to handle it. Use the remaining water first if you can. Water flowers, rinse tools, or flush out muddy containers. Then open the spigot and let gravity do most of the work. If the barrel has a removable hose or fitting, take it off and let those parts drain separately.
One realistic example
Last November, I helped a neighbor shut down a 55-gallon barrel after a week of 28°F nights. The barrel looked empty, but when we unscrewed the spigot, about a cup of water poured out from behind the valve. That tiny bit was enough to freeze and crack the fitting by December because the valve was left closed and pointed slightly upward. The barrel body was fine. The $8 spigot was not. That’s the kind of annoying repair winter storage is supposed to prevent.
Cleaning Beats “Storage” More Than People Think
If your barrel collected a summer’s worth of roof runoff, it probably has grit at the bottom. I wouldn’t pack that away dirty unless you enjoy opening it in spring to a swamp smell and a film of sludge. A quick rinse makes a huge difference.
You do not need to scrub it like a lab container. Just rinse out leaves, sediment, and slime. If there’s algae buildup, a mild soap solution followed by a full rinse is usually enough. Let it dry if you’re storing it indoors, especially in a basement or enclosed shed where moisture can linger.
One thing people miss: clean the screen or mesh at the top. That screen is what keeps mosquito debris and leaves out during the season, but it also traps grime that can smell awful when left wet all winter.
What To Do With The Spigot And Fittings
The spigot is the part I’d pay the most attention to. Barrel bodies are often thick enough to survive a season or two of careless exposure. Small threaded fittings are less forgiving.
If the spigot unscrews easily, remove it and store it inside. If it’s permanently installed, leave it open after draining so nothing gets trapped behind it. A closed valve can hold just enough water to crack in a freeze.
Be careful with plumber’s tape, rubber washers, and small gaskets. Throw them in a labeled bag along with any hose adapters. Otherwise, spring setup turns into a scavenger hunt, and people end up using the wrong washer, which causes slow leaks from day one.
Don’t Forget The Base And Diverter
The barrel itself isn’t the only part that matters. The stand or base can shift over winter if it sits under snow or ice. I always make sure the barrel is set on something level and stable before storage, or removed entirely if it’s a stacking base that could crack.
Downspout diverters are another easy-to-forget item. If your barrel system uses one, disconnect it or switch it back to normal gutter flow. A diverter left in winter can clog with ice, and that can send meltwater where you don’t want it.
Common mistake I see all the time
People drain the barrel but leave the hose attached “just for now.” Then the hose traps water, freezes, and splits near the connector. In spring, the first heavy rain leaks right onto the foundation or spills beside the house. The barrel is innocent; the forgotten hose is the problem.
When Winter Damage Is Not A Big Deal
Not every symptom means the barrel is ruined. A little discoloration inside, a light film on the walls, or a slightly warped lid usually doesn’t matter structurally. If the barrel is still holding shape and the fittings are intact, those cosmetic issues are not worth panicking over.
A slight frost on the outside is also not a problem if the barrel is empty and disconnected. What you want to avoid is standing water anywhere in the system. No water, no expansion pressure, no crack.
Spring Re-Start Is Easier If You Store It Right
The best winter storage setup makes spring setup boring, and that’s the point. If you’ve kept the parts together, you’ll be back in service fast. Before reconnecting in spring, inspect the barrel for cracks near the spigot, check the screen for holes, and make sure the overflow path is clear.
If the barrel sat outside, give it one more rinse before using it again. Dust, spider webs, and a little roof grit are normal after months of sitting. A five-minute cleanup beats dumping dirty water on your first garden beds of the season.
A Practical Way To Decide What To Do
If you’re standing there in late fall wondering whether to move the barrel, don’t overthink it. Use this quick test:
- Will freezing temperatures stick around at night? Then drain it now.
- Do you have a safe indoor spot? Store it inside.
- Can you’t move it? Disconnect it, drain it, and leave it dry outside.
- Does the spigot or hose still hold water after draining? Open or remove it.
- Are there loose fittings or old cracks already? Don’t risk leaving it exposed.
That’s really the whole game. Winter doesn’t care how expensive the barrel was or how nicely it caught rain in July. If water gets trapped, something gives. Store it dry, keep the fittings from freezing, and you’ll thank yourself when the first warm storm rolls in and everything still works.
