Step 6 - Taking Away the Old Putty

There are many times when the putty is very hard, causing problems when trying to remove pipes or nuts. It also makes it harder to install new nuts or pipes into the bath tub. To remove the old putty, you can use thinner, or you can scrape it carefully with a utility knife.

Step 7- Installing the New Piping

Look under the tub and attach the tee to the drain and the overflow pipe using a wrench.

Step 8 - Attaching Overflow Assembly and Drain

These 2 parts must be attached to the drain pipe that is protruding out from the floor. You can attach it by using the adjustable wrench.
