How to replace a tub waste and overflow drain assembly by yourself.

How to replace a bath tub waste and overflow trip lever, with a new Gerber brass trip lever waste and overflow assembly. There are many different scenarios that you may run in to, that may be much more difficult then the example I will be showing on this page. For example, if your tub drain waste and overflow is on a slab, or not accessible from underneath, or below the bath tub, you would need to open a wall behind the tub waste and overflow to gain access to the trip lever tub waste assembly. The following instructions will help you remove and replace your bathtub trip lever waste and overflow with a brass Gerber trip lever waste, from underneath the tub.

Tub Drain TrapThis is a picture of the tub trap under the tub, you can see the old tub waste connected to the bottom of the tub on top, the connection of this trap to the main drain is not up to code, but it's an old house.

Old tub drain removedIn this case I was able to loosen the nuts and remove the trap U bend from under the old tub waste with no trouble, sometimes the nuts will not move or will break, sometimes it is soldered and cannot be removed, this can make the job more difficult, you may need to cut the old waste to remove it.
Once I removed the old waste I saved it whole because I will need it to set up the new one. With the old waste and overflow removed you will need to clean the port holes, do the best you can, some very old stains just cannot be removed.
In this picture you can see the stains I was not able to clean. But it is now ready for the new Gerber Waste and overflow to be installed.
Gerber Waste and OverflowI personally prefer Gerber brass tub waste and overflow with a trip lever assembly, This is it new in the box with all the parts I need. I do not like any type of plastic waste and overflow assemblies and will not use them. To save yourself allot of time and trouble, use the old tub drain assemble as a template to set up the new one. the new tub waste is adjustable and can fit a verity of tubs, some tubs are extra deep and you will need to get a Gerber Tub waste to fit a larger or deeper bathtub.
First I lay the new Gerber tee over the old tee, notice the tees are different, this is not a problem because what needs to line up are the drain shoe and the overflow stand pipe.
With the tee set with the overflow inlet sitting in alignment with the old overflow inlet put the nut and washer on the overflow, (the fitting in my hand is the overflow) then line it up with the old overflow, the tee is a slip joint and you can push the overflow tube in or out till it lines up exactly as the old one. In some cases you may need to cut the tubing at the end of the overflow to make it fit.
Once you have the over flow tube lined up with the old overflow inlet screw the nut to the tee and tighten the nut.
Make the nut snug enough, so that the tube will not slip in and out of the tee if you hold the assemble from the overflow pipe. check this again after you have added the shoe and the tail piece, we will tighten more before we slide it up under the bathtub.
Now do the same with the shoe (the fitting in my hand is the shoe) Don't forget to install the nut and the rubber washer, (no you will not need to use Teflon tape on the threads or over the rubber washer. Some pipe dope on the washer wont hurt.
Now you need to look very close make sure the center of the overflow tube lines up with the old overflow with the top of the old and new shoes even with each other, you may need to readjust the new overflow tube because of the deference in the shape of the shoes.

Tub drain replacementThis is what I found when I started, silicone the homeowners best friend, if it does not work, just keep packing it on. Any way remove the 2 screws
Gerber tub drain overflowThe trip lever cover removed, this one did not have any linkage or stopper in it, it was long gone, some handy man may have taken it out.
  Old tub drainWith the trip lever plate removed there is nothing holding the overflow assembly to the bathtub, some handyman may have used silicone to stop a leak instead of just replacing the washer.
The next step is to remove the drain plug or spud from the bottom, there is a tool made to remove the spud but I never used one, a good pair of Channel locks and a screwdriver has always worked for me.
Just put the channel locks into the spud, put the screwdriver between the handles and turn counterclockwise, or to the left if you don't know how to read a clock.
Sometimes the tub drain is so old it will not turn and will have to be cut off, this can be a real pain and you could damage the bathtub beyond repair. If you cannot get it to turn
