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, includin g 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/under-sink-wat er-filter/moen-CAF87254-wickston.php) is a little unique, in that it dispen ses 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 t his model), but it won't work in my current kitchen, as the owner already h as a faucet installed.
What I would like to do is use the actual filter portion of this system, bu t connect it to a new sink-top spout.
My question is how to safely make the connections from the plastic tubing t hat 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 connecti ons 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 nee d to know to do this right?
If I use a barbed fitting, how do I know what fitting size to get? Do I ju st 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 the re some rule-of-thumb to how the ID of the tube relates to the fitting size ?
