I heard a clicking or dripping sound today. Long story short, I found a drip where indicated here at one of the fittings on the mess'o'pex that exists to hold a water filter. (I think I caught it just as it started)
During my dealer walkthrough, I took one look at that zig-zag construction and decided there was no way I would trust it with the stress of filter replacements, so I got a Brita ;-) Apparently even without touching it, it decided to leak.
I finger-tightened the clamp thing at the arrow and that seemed to stop it for now, but for future reference, where is the cold water supply cut-off for it? Is it the silver knob on the right of the photo? Or does that just cut off the water from the filter zone to the faucet?
And should I be turning off city water every time I leave the AS for an hour or more? Can I remove all of that mess and direct-connect the sink so I can sleep better?
