Query: One problem, One simple fix.

The one problem was water leaking out where the two halves of the filter screw together. It had the appearance of having a place to put a small rubber O-Ring in there & then screw the two halves together, but it did not come with one, nor did the instructions & diagrams show any such thing. Anyway, I took ours to the hardware store & got a rubber O-Ring for this. It worked 100%. No more water leaking out the middle & the WATER PRESSURE went back to normal. Why they do not come with this rubber O-Ring is beyond me??? This is an easy & very cheap fix. The rubber O-Ring was about two dollars & it has lasted through several filters so far.
