This Instructable is to help people who are first timers like me.

This is the first time I have attempted any plumbing repairs and the videos are a little wonky.

Let me know in the comments if you have any suggestions to make this job easier.

The tools and parts cost less than $25 US in 2017.

Thanks JC

Step 1: Choose Your Tools

Items needed to remove and replace a modern screw in bath tub drain (not all drains are like this).

A bathtub drain wrench or sometimes called a drain key.

The new bathtub drain.

A long screwdriver, plumbers pliers (channel locks), a properly sized wrench to fit the body of the drain key, or really big channel locks (vice grips).

Step 2: Remove the Old Drain

Insert the Drain Key into the drain. One side is bigger than the other so it fits several sizes.

Rotate the key counter clockwise with a screw driver through the body of the key.

Note: if you struggle and the drain won't turn move up to a wrench of pair of channel locks like I did.

Slow and steady pressure, (NOTE) DO NOT hit the tools or the drain with a hammer or jerk on it as this may break the bottom out! Slow and steady wins the race...

Step 3: Clean the Seating Area and Apply Fresh Plumbers Putty

The new drain needs to have a fresh clean area to seat on with a healthy amount of plumbers putty.

First clean all debris out of the area .

Apply a fresh ring of plumbers putty.

1. scoop out a couple quarter size chunks of plumbers putty.

2. roll the putty between you palms to make a nice long roll like a playdoe snake.

3. place the ring of plumbers putty around the drain hole and overlap a little using your fingers to shape if necessary. (don't worry about too much putty as it will squeeze out and be easily removed with a gentle tearing motion).
