Price Pfister to Pegasus - Can I Do It?

All,
I have a tub and shower faucet set that is currently Price Pfister - a single handled model. Tonight - I purchased a Pegasus set from Home Depot - 7000 series - also a single handled model. I have some experience with replacing lav units - but am ignorant when it comes to shower and tub. I think i can handle the shower head and spout with no problem (if i dont have to cut the pipe for the spout), but the main control is another issue. Tonight when i opened the box, i noticed that the all of the plumbing behind the control is present (does this make sense)? My question...Can I possibly just replace the outside piece of the main control? Or am I going to have to break the tile to get to the supply lines and reconnect and replace the entire existing configuration?
Any insight is appreciated!

take the old fixture off. once that is done, you can see what you have to mate up with and what would be required to get your new fixture to work. if you cant get it off, you wont be installing the new one anyway.
start by takign the old fixture off.

You won't be able to tell until you start taking it apart. If you do have to get into the wall, rather than busting out tile, there should be another way to get to the plumbing, like on the other side of the wall from the shower plumbing. I get to mine from inside an adjacent bedroom closet. It is a lot easier to cut out a piece of sheetrock and then patch it back up, even if it is a little sloppy afterwards, or screw up a piece of plywood as an access door. You'd have to move clothes to see the patch.

Chris, As a novice, I had the same problem and I talked with a lot of people about it. The general consensus was that if you use the same manufacturer for the new fixture, the old valve in teh wall might accept the new handle, but don't hold your breath. I tried to go from Price Phister to Kohler. If different manufacturers, your chances of them working together are slim to none. Probably done on purpose. Regardless, good luck. -David

Thanks guys...
I took off the old unit - and decided that I am going to order a new trim kit only from Price Pfister. No sense in me messing things up!
