    The connection from the 1/2" copper water supplies to the angle stop valves, is Compression or IPT fitting better? I just want the one that is less likely to leak down the road. Thanks...

    Properly installed, either is fine. If the compression is overtightened, installing a new one later might mean cutting the pipe back. You may need a puller to get the old ferrule off, but can reuse it - the nut might be pretty anymore, though.

    I have both and I prefer IPT for ease of fitting and removal, and less potential to leak. And if it does leak, at least you can apply (more) teflon tape and tighten it. Not so with compressions.

    Although I did manage to tighten a compression to stop it weeping recently. Guess I got lucky and just hadn't tightened it enough when I first fitted it.

    What's the trick with getting both risers from the IPT angle stop valves pointing strait up? Is it possible?

    trick

    There is no trick. You just tighten them further, assuming you have not already bottomed the pipe in the valve.

    With all the junk my wife piles under the sink, you can't see them.

    There's a good argument for compression fittings, BTW -- I put them on loosely, see how the risers want to lie, and then tighten up the compression nuts. In some cases, I'm best off pointing the stops down, rather than up.

    Asthetically I want them pointing up. I have a decorative wall hung sink w/ exposed plumbing that hits you in the face when sitting on toilet. Maybe this is a good argument for compression; would rather have IPS though...

    Did you Know

    Did you no that there is a new style fixture shut-off valve. Its copper tube sized and you just push it on to the 1/2" supply tube. Looks neat and I beleive it's Talon that makes them.

    Good Luck,:):)
