Hi,

I am on a tight budget, but trying to put in an under-sink water filter to address problems with the lead water main on my street.

I actually have such a filter that I used a couple apartments ago, including multiple filters. Just the savings of using the expensive filters that I already have means that I'd really like to use this filter, if I can. The system (Moen ChoiceFlow, http://searchwaterfilters.com/moen/u...4-wickston.php) is a little unique, in that it dispenses the water THROUGH the faucet, coming out of a tiny spout that is on the bottom of the faucet. That worked great (not sure why they discontinued this model), but it won't work in my current kitchen, as the owner already has a faucet installed.

What I would like to do is use the actual filter portion of this system, but connect it to a new sink-top spout.

My question is how to safely make the connections from the plastic tubing that the filter uses. How do I safely connect the plastic tubing outlet of the filter to the inlet of a new filtered water spout? Are barbed connections reliable/safe for use with city water pressure, or would I run the risk of flooding the apartment? What if I use a clamp? Are there things I need to know to do this right?

If I use a barbed fitting, how do I know what fitting size to get? Do I just get one that seems to fit tight, or should I actually measure something? I have a caliper, so can measure the ID of the tubing accurately. Is there some rule-of-thumb to how the ID of the tube relates to the fitting size?

Thanks!
Emily
