Plumbing – How to snake a bathtub with no overflow drain

bathtubclogdrainoverflowplumbing

Our upstairs bath tub has been taking longer and longer to drain and my wife has finally tasked me to fix it.

Yesterday I literally emptied an entire bottle of Liquid Plumber down the drain (following all the directions of course – well, except the fact I used the whole bottle!) and still no difference.

So I borrowed my father-in-law's "snake" and went online to learn-up on how to snake a bathtub. I found two videos that were particularly helpful:

Both of these methods require an overflow drain to be present in the tub. In both videos, this overflow drain was located about 18" above the main drain. However, my bathtub looks like it's wired a little differently:

Instead of an overflow drain approximately 18" above the main drain, there is this mechanical lever that engages or deactivates the bath plug. Above that is the faucet, and above the faucet is the hot/cold/on/off control.

So I ask: given my setup, and given what I've learned from these two videos/methods, what's the best way for me to unclog my bathtub? Thanks in advance!

Edit: per @BMitch's suggestion, I checked around the perimeter of the "bath plug" and it appears that it is not sealed around a slot running along the very bottom. In other words, it appears that there is actually an opening there, starting around "4:00" position and extending to the "8:00" position…

Your tub has an overflow drain. You just have to find it. Remove the two screws next to the combination drain toggle & overflow plate. Now gently pull up to reveal the overflow hole and the drain plug:

Get out your snake (you've got a snake, right?) and thread it down the newly revealed hole. Also remove the single screw holding the drain screen. Use some sort of semi-flexible plastic rod to clean out the horizontal section of the drain (a suitable tool comes with some bottles of drain cleaner, else you can improvise).

Don't bother with drain cleaner -- it is not right for your situation.
