One word of warning, do not attempt to replace your own toilet without taking all the pre-cautions:

Violating or ignoring local code restrictions.

Using pipes that are too small.

Attaching copper to galvanized without using a brass or dielectric fitting between the two.

Not using PTFE tape or pipe compound at threaded joints.

Not leveling your fixtures when installing them.

Not installing an air gap filling for fixtures.

Cutting supply stub outs too short to install the shutoff valves onto after the finished wall is in place, or

Not properly aligning tubing into fittings or stop valves. (Forcing the nut onto the compression ring at an angle when the tubing is at an angle will cause a leak.)

When turning the water back on in your home, always run the outside hose valve or flush your toilets to bleed dirt and air from the lines. This debris can cause problems in your sink faucets and other plumbing trim.
