So when it it rains, it pours .. sometimes a little too literally

[Delphinus]

So at some point yesterday evening between about 7pm and 9pm my RO/DI decided to burst. I came downstairs to feed the fish to hear the sound of water spewing. After a moment of panic I realize all tanks are fine. But I definitely hear water spraying .. so I peek behind the furnace and there's this wonderful water fountain spraying like nuts.

Upon inspection it looks like one of the clear canisters for the prefilters developed a crack.

I wonder, can these things be replaced without buying a whole new unit? It's just the clear part itself. Can anyone recommend any place to look for something like that? I went to HD tonight but of course they didn't have anything quite like it (except for whole new units)..
