Is your tub is not draining and doing its job rightly, you might have to take this out and clean or even replace it if required. Rest assured in just some simple steps you will have your tub drain out & resolve your tub trouble.
It is unfortunate but true: With time your tub drains clog or even corrode. Your tub is put on the test daily as you and other members in your family bathe, and forcing all types of products—and huge amounts of hair—through its drain and in the pipes beyond. And day will come when the drain stops to function. When it happens, you will probably have to remove your drain for check, and followed by careful cleaning or complete replacement or using drain hair catcher. This removal process is not particularly tough and time-consuming, and taking anywhere from some minutes to hours from beginning to end, which depends on a type of drain that you are dealing with. Still, as with everything DIY, some simple instructions can help this task to go very smoothly.
Whereas tub drains differ by its type, they are sorted in 2 broad categories: easy drains (that includes foot lock, lift-n-turn and roller ball types) or drains with the trip lever (like pop-up & plunger drains). The instructions to remove both the types appear below. Find your style of drain, and follow this step-by-step process to remove this yourself.
Simple Drains (Roller Ball, Foot Lock, or Lift-and-Turn)
Mild cleanser (optional)
Drain key/smart dumbbell
Blow dryer (optional)
Before disassembling your drain, it is very important to note the condition. Huge amounts of mildew, rust, and decay might indicate the higher problem, in that case professional help might be require. But, if the tub is in the good shape, just pull on your rubber gloves and start on your important mission.
For the foot lock and roller ball plug, just rotate this counterclockwise until this separates completely from your drain shaft.
In case of the lift-and-turn type of drain, lift a plug and free this by loosening its setscrew below. Suppose you find that setscrew on the lift-and-turn tub is stuck, then series of light or medium taps can help to loosen this out. Use your screwdriver or wrench to nudge this in motion if essential, but you need to be careful when using drain hair catcher and not use a lot of force that can damage your drain.
