Hi there, I am renovating a bathroom in my new(old) house. I need to replace the toilet but it doesn't have a shut off valve. Is this something I can do myself. I am doing all the other reno's myself. Are there any links or written directions for this. I'm told now with compression fittings that I should be able to do myself. Any suggestions would be greatly appreciated. thanks Oh and if someone could give me a list of things I would need.
