Just got the C360 yesterday and hooked it up no problems. But I was wondering what the 2 extra O-rings that came with it are for. They look like the same ones that are on the valve block. Any info would be great.
Haha... Funny in that I had the same question! I figured they'd be for the valve block, but also figured that they'd at least tell you what they are for in the instructions! Having water sealing parts left over after a new filter install can be kind of nerve wracking!
