How do I install Moen bathtub hardware?

Question

bought Moen faucet and shower head instructions are kind of vague as to how to install

Answer 1

First: What type of "Moen Hardware?" The top $$$ "Fixtures?" Or are they in the Lower Price range?
If they are "High Dollar" fixtures, then I'd suggest spending the extra money on 2Hrs. of a "Service-Call" from a "Licensed-Plumber." Doing that will ensure that your "fixture" will not be ruined(Scratched & Functions Properly).
If you still plan on doing-it yourself, then you will need these tools, to remove your old "Hardware," and then to install your new "Fixtures."
A "Cresent"(8"-10" Wrench), a pair of "Channel-Locks"(420-440 Pliers) if you have a pair of "460 Channel-Locks" as a "back-up," even better, and a "roll" of "Teflon-Tape" instead of using "Pipe-Dope,"(Thread-Compound) is better, to use in this situation.A Tape Measuer. Finally, a couple of Ol' Clean Rags. A Soft Old Towel(s) would be best.
To remove your Old "Shower-Head" use the "Cresent"(Wrench) there should be "Notches"(Flat-Spots) that look like "Grooves" where "The Jaws" of "The Cresent" will fit. It should be just behind the "swivel"(neck of the shower-head) and where it "thread's" on to "the neck"(coming out of the wall), turn it "Counter-Clockwise"(Rightie-Tightie, Leftie-Loosie). If the "neck" starts to turn also, then you will have to use your "Channel-Locks" as "A Back-Up" use your "Rag" and wrap it around the the "Neck" so that you DO NOT "Bite" the Finish on your shower "neck" with the teeth of your "Pliers"(Channel-Locks). Once it's removed then "wrap" the threads of the "shower neck" with your "Teflon-Tape" a few times, and install your new "head"(shower).
To remove the "faucet" you will need to "wrap" it with your rag, and using your "Pliers"(Channel-Locks) turn it "Counter-Clockwise" also, being very careful not to "Bite" to hard on it, or you could "Crush" and even "Brake" off "The Nipple" inside the faucet, that is "Big-Trouble!" Once you have removed the old faucet, you will have to see what size "Nipple" you will need to use with your "New Faucet." It will be "1/2" Dia." and its length could be anywhere from "2"-8" in Length."
If "The Nipple" was Copper and "Sweated"(Solder'd) together, if you feel "Confident" you can "Cut and Sweat" your own "Nipple" or just buy a "Galvenized-Nipple" from your local "Home-Center"(Home Depot). When you know the size "Nipple" that you need, "wrap it in "Tape"(Teflon) and "Thread-It" into "The Valve"(Control-Hot,Cold) first, "snug-it" with your "Pliers" and "wrap" the other end(treads) with "Tape" and "make-up"(thread) the faucet using your hands. When you have it "Hand-Tight" then you will have to be real careful, from there to make it "snug" against the tile. If you try to "tighten-it" too much, you could "crack or brake" the tile next to it. You just want it "snug" so it looks like it is part of the tile itself, and so the faucet won't move, if it is "bumped."
Remember, just take your time, and be careful, so you don't "scratch" your new "Fixtures," or "Brake" another item that you have to replace, or have someone replace the broken parts or pieces; like A Plumber, or Tile-Man....
Good Luck.

This job has a rating of 8 for hardness on a scale of 1 to 10 and unless you can solder with out getting leaks I would get a plumber to do this work
