Product review (3 stars): Filters Leaking
I've been ordering these water filters from Water Sentinel ever since we purchased our home (2014).  As of this writing Water Sentinel is the only reliable source for the WSG-4 Filters.  However, this last order (2 each) apparently was part of a bad batch.  Both filters leak.  Initially, I thought I did something wrong when I replaced the first filter, because it leaked.  Then I replaced with the second filter and this filter is leaking as well.

I'm not giving Water Sentinel a bad review because they have fulfilled there obligation, but I think Water Sentinel may want to check with the manufacturer of this product and see if there is a problem on the manufacturers end.
