Hi!
Great news, picked up a regular pipe wrench for $10 and got the old nipple off (was also dousing with penetrating oil).
Terry - The Delta faucet does look easier to install and I appreciate the information and search help, but I am not seeing many options for spouts that use that adapter (only found 2-3 options in nickle but I didn't like them). It may be that Delta doesn't give that much information - going to their website, it is hard to find any install details on any of the spouts, for anything that includes the adapter or requires it. I liked this one, but looks like it is threaded: Delta RP61357BN
There were also a few slip-on types that I like, including the Kohler Bancroft (which comes in threaded or slip-on), and Kohler has detailed install instructions available.
So the question is what length brass nipple do I get? Are they hard to cut (which I'd rather not do since I don't have tools for that)? Or do they come in fairly standard sizes? The current one was 4.5" long with 1/2" in the wall.
The Kohler spout instructions specifically says for threaded the nipple should extend 4-1/2" past the finished wall, so I guess that would require a 5" nipple? The slip on says the tube should extend 2-1/8" - 3-1/2" past the finished wall, so guessing that would be about a 3" nipple (1/2" in the wall + 2.5" out). Do slip-ons need a non-threaded smooth ended nipple?
The Delta doesn't say and I can't find any info/instructions, but digging through the reviews someone said to use a 4.5" threaded nipple (not sure if that is total or what needs to stick out of the wall).
I live in a remote area and there are not a lot of stores to shop at, so while I can go to the 1 plumbing supply or the 1 big box store nearby for parts, I have to order any nicer spout online, so I want to make sure I have everything correct before I order.
At this time, I'm leaning toward the Kohler threaded, so will get a 5" brass nipple threaded on both ends. Does that sound right?
