Never had a problem drinking water from our FW tank which goes through our OEM Pur filter. I change the element once each season and No, our filter housing has never broken. We do turn off the water when leaving the unit for any length of time. Even if it did leak, it wouldn't hurt our floor, just be a mess to clean up.
I buy the filter elements from HD for much less than CW or any other source. The micron level is variable depending on how "pure" you need the water to be. The 5-micron filters work for us and do not reduce water flow that much.
