Water filter canister broke apart on its own

This is not unusual with cheap filter housings. If I was you, I certainly wouldn't use the same brand as a replacement.

People always look puzzled when I tell them that I always shut of the pump switch and always shut off the campground water supply if we leave for a while.

Do you have a good pressure regulator at the spigot? I have a Watts 283A and am comfortable enough to leave the water on when I am away from the RV for a few hours.

As for the failure of the filter - there was a thread on the Flagstaff forum where the filter housing "came off" from the head - more like walking back on the threads, as opposed to the break you described. The fix was to either change out the filter that came with the RV or put some other means of preventing the housing from unscrewing itself.

Yes, I have a Watts regulator. I am at my seasonal site and have spent more than 500 nights here. After 4 years and 11,000 miles it just had enough I guess. One of those things that just happens and you can't explain it.

Here's a thread, titled "Exploding water filter" where somebody had the same experience as you. You will see that there are different causes.

Mine was an interior OEM cartridge filter canister.

Thanks for clarifying. I find that many times on these fora pertinent facts are omitted from the initial post and it is usually only after the OP returns to clarify that the root cause can be determined. Thanks for following up.

It certainly looks like the canister failed possibly due to age. I don't know how easiy it is to replace the whole unit but on my Flagstaff it is easily accessible, and were I you I'd probably change it out for one that has maybe a different material for the canister.

that's one reason I use a separate shut off valve on the incoming water that just takes a 90 degree push of a lever to cut the water flow quickly and easily.

Could you share the brand name, please? I need to filter my RV water and am looking for filters, it would be good to know what to avoid.

I use this one instead of the RV junk filter. Not only cheaper but higher quality. I learned from experience. The filter housing broke in my stick house and the water ran all day. Several thousand dollars of damage. Fortunately we had good insurance.
