Outdoor basketball hoop question

My son's got one of those. The top is almost flat, enough so that we were able to use paver stones for weight in the winter. I wasn't comfortable with leaving the water in it.

You answered your own question.

if you leave the top open so the water can expand, won't that work ok?

You'd think so, but I left a watering can filled with water on my porch. It froze solid and the ice pushed the bottom of the metal can into a round shape. Very weird. Half the top of the can is wide open - plenty of room for expansion.

I empty mine & lay it down in back yard, but that is because I transport it to my church gym and set it up as a 3rd hoop for a little

If I did not have to move it every winter, I think I would fill it with sand and leave it up year round. I am pretty certain leaving water in would crack base, but with dry sand, you are good to go all year.

It's a worthy thing to worry about. I'd be inclined to cruise to the manufacturer's web site and look around for a FAQ or a customer service phone number. It has to be a pretty common question ya'd think.

I was interested enough to search on it and found this:

"The best option to fill your portable basketball goal is with non-toxic antifreeze, which is recommended to protect pets and the environment. Antifreeze will keep the base from cracking from frozen water in the winter and also keep the bacteria to a minimum in the summer heat."

If the ground was warmer than the air then it probably froze from the top and sides down towards the ground, creating a nice plug that apparently was stronger than the bottom of the can.

Fill it with 65%/35% ethylene glycol antifreeze/water. or pure propylene glycol with no water. If it freezes then, you've got bigger problems than a busted basketball hoop.

Wow, never thought of that. That sounds like a great idea. The website you gave says two gallons should do the trick. Thanks!

And thanks to everyone who responded.

That makes sense. It was on a cement porch where snow still melts when it lands - the cement hasn't totally cooled down yet.

Did you ever think of contacting the manufacturer? I'm sure they Have had this question before. I would think freezing water would be a issue when designing it.

What do you mean about having a bigger problem if it freezes?

Anti-freeze all over the place. Good if you're trying to get rid of the neighbor's dog permanently, but otherwise, no.

Off the top of my head, I think he means it's like -70 deg F....

Unfortunately for this problem, water freeze from the top down.

This property of water, however is fortunate overall, since none of us critters would be here if water froze from the bottom up.

Hit Walmart or a hardware store and get the "RV" anti-freeze. It is non-toxic, made to be put in water lines for winter storage.

It tells you right in the instructions to use non-toxic antifreeze in it.....

Ever heard of antifreeze? Check the volume of water to see how much antifreeze you need for the extreme temperature you expect. And check with the manufacture if antifreeze is ok (it undoubtedly is ok).

yeah I remember reading that once, I don't recall why...enlighten us...
