Portable basketball hoop winter storage, and the freeze that splits bases

The decision, in one paragraph

Portable hoops are sold as outdoor products and specified for it: Lifetime's boards use UV-protected inks and all-weather nets, Escalade's weight bag is rated for rain, snow and intense sun, and every maker on this site publishes an outdoor warranty. Nothing about the pole, the board or the rim needs a garage.

The exception is a water-filled base in a freezing climate. That is the one component winter reliably ruins, and it ruins it in a way no warranty covers. So the whole question comes down to what is in the tank.

Why a water base splits, and where

Water expands by roughly nine per cent when it freezes. A sealed plastic tank filled to its published capacity has nowhere to put that expansion, so the pressure goes into the walls. Bases do not usually burst spectacularly; they develop a split along a moulding seam or around the fill boss, and then they quietly empty in the spring thaw.

That is the failure mode to watch for: a hoop that was stable in October and tips in April has almost always lost its ballast through a freeze crack. And a cracked base cannot be repaired properly — plastic welds on a load-bearing tank do not hold up.

The three options

1. Drain the water and leave the hoop standing

Unscrew the fill cap and tip the base toward it, or siphon with a hose. The risk is the obvious one: an empty base is a light base, and winter is the windy season. Lay the hoop down flat against a wall or fence for the winter, or strap it to something, rather than leaving a 54-inch board standing on an empty tank in a gale. Wind and tipping covers what a board in a gust actually does.

2. Swap the water for sand

The best answer if you can face the work. Sand does not freeze, weighs more than the same volume of water, and cannot leak away through a crack. It also means never making this decision again. The catch is that filling a base with sand through a small cap takes an afternoon, and emptying it later takes longer — how to fill a portable base has the method and the weights.

3. Leave the water in and accept the risk

Defensible in a climate where the ground freezes for a few nights rather than a few months, and defensible if the base is only partly full — there is headroom for the ice to expand into. Not defensible where the tank freezes solid for weeks. If you take this route, leave the cap slightly loose so the expansion has somewhere to vent, and check the base in spring.

Four jobs worth doing before the first freeze

1. Move the hoop off the snow route. Decide now where the shovel or the plough goes, and put the hoop somewhere else. A base clipped by a plough blade is a dead base, and a hoop parked in the drift line spends the winter in salt.
2. Go round the hardware with a wrench. Board bolts, bracket bolts, pole splices. Thermal cycling through a winter loosens everything, and the check is easier now than in March. How to stop a hoop from shaking has the order.
3. Take the net off, or accept losing it. A nylon net that spends a winter frozen, thawed and UV-bleached is a net you will be replacing anyway. Keeping a spare in the garage is a $5 to $15 item.
4. Keep road salt off the pole. This is the real corrosion risk for a portable — not rain, but salt splash and salted slush sitting against powder-coated steel at the base. Rust prevention covers what to do about it and what not to bother with.

If you do store it inside

Some people have the garage space and would rather use it. Two notes. First, you still have to drain a water base — rolling 290 lb of water into a garage is both unnecessary and awkward. Second, lay the hoop down rather than standing it: a tall hoop in a garage is a thing that gets reversed into.

Getting it in there is the usual tilt-and-wheel job, with the rim lowered first: how to move a portable hoop has the method, including what not to grip.

What to check in spring

• Base ballast level. Refill a water base to capacity; it will be down from evaporation even without a crack.
• Seams and the fill boss. A dark damp line on the plastic is a split.
• Every bolt. Again, with a wrench.
• Rim level and net. A rim that sits low has usually been hung on, not frozen.
• The pole at the ground line. This is where corrosion starts on any hoop, portable or in-ground. How long a hoop lasts covers the pattern.

Do that in an hour on the first warm Saturday and the hoop plays like it did in October. Skip it for three years and you will be shopping again: best portable hoops is where that ends up.
