"Homeowner Ian" likes nipples, but unless you use brass, the galvanized nipples will rust and close up.
Most people stand in front of a toilet.
I don't see how anyone would be standing on a shutoff behind a toilet.
I can't even imagine how you would do that.
You would have to put your leg under the tank to do that.
What the heck is Ian doing in his bathroom?
Ian, what the heck?
Here we go. The riot has started.
I like nipples because if the shut off were to leak you can tighten it up.
Not that it will leak.
I'm always catching old compression fittings leaking though. Especially if they get kicked or hit by the mop.
So, I have replaced most of my compression fitting in my house starting with those that had developed leaks.
Brass nipples are the business. Ten years later you'll be able to whip that old shut off off the nipple and slap on a new one, without any risk of a crimped pipe or struggling to get the compression fitting off.
Plumbers like compression fittings because many homeowners do not understand them.
There's not much to understand about nipples. I also like the way they are more sturdy than copper pipe in exposed situations.
And shiney.
I've started using soldering for valves a lot more too. Not for angle stops though (I like nipples), but certainly for ball valves and I would never use a compression fitting behind a wall.
So the next time a plumber comes to your house, if he does not show you his nipples, show him the door.
