Very simple tap connection question
Posted by Russ on February 08, 19101 at 12:52:24:
I'm installing water supply lines for a laundry room and would like to use sweat fittings wherever possible so nothing ever leaks :-) I'm putting in a wash machine outlet box and would like to install female threaded fittings on the end of the 1/2" copper and then attach the taps to these (sweating the taps onto the pipe would be my first choice but isn't possible because I'd melt the outlet box plastic). So here's my question...

How do I install the female threaded fitting (FIP I think it's called) so that the when I install and tighten the tap, I have the tap facing forward AND tight enough not to leak. I notice there are three diamonds stamped in the side if the female fittings and I'm wondering if this is used to know how the fitting should be installed when soldering.

I've looked in countless books and can't find an answer to this seemingly simple question.

Thanks in advance,
Russ
