trying to remove old filter..which direction do I turn the device?

Asked by: jack
It's tricky, keep at it, be gentle and turn left - it will eventually turn - if you get frustrated leave it for a while then go back later.

Universal Undersink Water Filtration System is rated 3.0 out of 5 by 2.
Rated 1 out of 5 by from confusing Well, here I am, trying to install this "easy install" water filtration - so far, it doesn't look like the picture - it resembles it but i checked the model number and that's what it says on the box, 2nd it would be nice to know ahead of time - since I already went to home depot once today, that now you need an adapter or valve because it doesn't come with it. Says right in the booklet NOT INCLUDED. Hey here's a HINT: HOW ABOUT WRITING IT ON THE OUTSIDE OF THE BOX SOMEWHERE!!! Not nice - spending the day running back and forth instead of getting this thing installed. The directions seem clear but really are not - going to watch the dvd now. also - the mounting screws don't fit. Is it me, or is it Dupont? Hmmmm, will keep you posted! All I can say so far is not as EASY to install as it should be!!

Rated 5 out of 5 by from Great undercounter filter. Perfect solution to our refrigerator filter system going bad. We capped it off due to water leaking, (line froze I guess) so under the sink, the line to the fridge is where we hooked the new filter. Perfect for us.
