I have a "Freedom" one piece faucet with shower diverter. As I look at it there are three
Short pipes that apparently go into the wall. Obviously I can not twirl the whole thing around to screw in three different pipes. Can I get into this to do it from the front or am I going to have to go into the wall and approach it from the back. I don't want to chop up the wall until I am absolutely sure I have to.

We need more details. What kind of pipes do you have. Copper or plastic? If you pull the knob and the chrome cover plate can you see all the connections? Let us know. Tom

I fear I have found the answer. I was hesitating to take ANYTHING apart before I was ready to actually delve in. Most of the pipes in the house are plastic. However looking at the url below. It appears to me that I need to tear up the wall. Would you agree? My faucet is the one on the bottom.

If you pull the knob and the chrome cover plate can you see all the connections? Answer this question and I'll tell you if you have to open up a wall. Why do you wish to replace it? Can it be repaired? Back to you. Tom
