Step 5 - Cut the Hole
If required for accessibility, cut the hole to gain access to the location of where you will install the tub overflow drain. Make the the hole is big enough to allow you entry but small enough to minimize the repairs needed after the fact.
Step 6 - Remove the Old Overflow Tub Drain

Step 7 - Install New Piping
Take the new piping you have purchased and install it. Add Teflon tape to the piping to help prevent future leaking. Apply the Teflon paste at the top of the overflow. Tighten the bolts and test the seal.
Step 8 - Fill the Tub
Test your work out. Fill the bathtub and check to make sure that you do not have any signs of visible leaking in or around the tub.
Step 9 - Close Up the Hole
Close up the hole by adding a removable door and hinge or by spackling over the hole you have made. Paint it to finish it off.
If you find it hard to get the drain pipe off, you can use some WD-40. You might need some help to hold the pipe while you are unscrewing it from the bottom.
