i am putting in a sub floor 3/4 inch plywood tongue and groove. i was just wondering all the low and high spots can they be sanded to form a level field? if so do i just attach the floor and then sand? i really dont want to use a floor leveler for fear of it making un-level floors entering another room. one more i have one really high joist and i wanted to know if it would be possible to either plane or sand that down to level ? im trying to install hardwood with a tile inlay.

DO NOT PLANE YOUR FLOOR JOIST. By doing that you making it weaker. If it is a pre-engineered joist it is made with a slight camber. If it is possible, replace the joist with a straight one. Before installing your hardwood, apply a layer of multi-ply plywood. It is 1/4" thick 5 ply plywood. Be sure to stagger joints over your 3/4". Nail as directed on the multiply. If joints in the multiply are up and down, sand them smooth with a beltsander. And yes, look out for high nails.
Also, a properly installed subfloor of 3/4" T&G plywood shouldn't have low and high spots.

if you have a very high joist i suggest planing down that joist until it is even. i recomend not sanding your subfloor because you will weaken it and make the floor feel bouncy and probobly crack the tile or grout. i recomend using a leveling compound to take care of any low spots and i would also aplly a skim coat to the entire floor to take care of any voids. this will also help your tiles to stick. i think you should put down hardi backer to provide a better base for your tile. apply this stagering the seams of the hardi backer from the seams of the plywood this will also help take care of any variation in the floor. good luck

I believe that any home improvement project is worth doing right. In this case that means that you should pull up the vinyl and start fresh. It will not be easy, but did the vinyl go down over another flooring, in the same manner that you want to do? What is the quality of the Subfloor (the real subfloor, upon which all of you weight will ride when you walk across it)? You will not know the answers to these questions unless you remove the vinyl, and it is important to find out. Do it right and in the long run it will add value to your house.

And just pay attention to the nails that you put in so you don't end up destroying your sandpaper afterwards.
