Cracked Water Filter - Freeze?

So, today I was cleaning out a box on the RV that holds all my "important things". I noticed all over the bottom of the box were these black pellets or beads and then I noticed my inline water filter was cracked and these "beads" were coming out of it.

I typically, coil up the water hose with the filter still attached and hook everything together so water does not come out of the hose and/or "things" don't get into the hose. I think what happened was that there was still some water in the hose and over the winter the inline filter cracked due to freezing.

No biggy, I need to order a new filter anyway, but thought I would pass this along. I never thought about protecting all this when I do my annual winterize.
  • If your filter froze with water in it then it is ruined. period. sorry.
  • I have had two of the blue inline filters crack some years ago, but none since. The cracks were not caused by freezing, just poor manufacturing. I toss the filters at the end of the season.

    x2 ... even without the risk of freezing, I wouldn't want to store water inside a hose with it closed up. There's plenty of "things" in the hose and filter already, and giving them water to breed in... yikes
  • The hose itself is generally okay with freezing; it's stretchy enough to not burst. Fittings and such are a different story.

    Glad you noticed the hole before hooking stuff up and turning on the water!
