My bathtub drain stopper won't stay open

follow this steps and fix it. God bless you
lear a clogged (not stopped) sink or bathtub with a plunger:

1. If you have a dishwasher, pinch off the rubber dishwasher drain hose that leads to the garbage disposer using a clamp or locking pliers. If clearing a bathtub, remove the drain stopper and cover the overflow opening with a wet rag.
2. Remove the sink basket or tub stopper and clean any debris from the drain opening.
3. Fill the sink or tub with sufficient water to cover the plunger cup, usually about 2 inches. If you are working on a double sink, seal the other sink with a stopper so the plunger can create a vacuum.
4. Set the plunger on the drain opening and repeatedly pump it up and down, then pull away sharply to dislodge debris. Repeat if necessary.
5. Turn on warm or hot water to flush loosened debris from the drain.
6. If the clog remains, use an auger (see below) or an expansion nozzle (see below) to clear the drain.

Clear a clog using an auger:

1. Remove the stopper or strainer. If unable to do so, disassemble the drain trap (see below) and feed the auger directly through the pipe. Make sure you have a pail and rags nearby in case of a water spill.
2. Release the setscrew on the auger and begin feeding the cable into the open drain.
3. Once the auger tip hits the clog, set the screw and crank the auger clockwise to break up the clog.
4. Continue breaking up the clog and moving it down the drain line with the auger. Once there is no more resistance to forward motion of the auger, stop and carefully remove the auger.
5. If the clog can't be moved, continue twisting the auger to possibly snag and retract the clog.
6. Once the clog is cleared, flush the drain with boiling water.

Does the tub have a lever to stop the drain below the spigot ?

In my part of the country, the type of drain you refer to is commonly called a tip-toe drain because you can use your toes to open and close the drain. Their locking ability diminishes over time and use, and eventually won't lock at all. They cannot be repaired, and must be replaced. You must remove the one you have to get the correct replacement because there are variations in the thread diameter at the bottom of the stopper.
You will need to use pliers large enough to grab around the white plastic underneath the top of the stopper that appears to disappear into the drain. Once you have the white plastic shaft secured with pliers, grab the very top (the chrome part) and twist it counterclockwise to remove it. Once that is off you will see a round piece of brass that looks like the top of a very large screw. IT IS! Using a stantard screw driver, again turn counterclockwise to finish removing the rest of the stopper.
A good hardware store should have a replacement for you. Be sure to match up the thread diameter at the bottom of the stopper.
To reinstall, you can reverse the steps or simply thread the complete assembly into place.

The lever it's hooked to under the sink it has a nut to loosen to pull lever back. Then the drain stopper will be able to be removed. Check out this link to get a look at the under neath to help you I hope.

There are two types of tub drain stoppers for the delta brand - lift & turn and toe tap.

Lift and Turn:
The lift & turn stopper for the bathtub unscrews counterclockwise while in the full up position.

Toe Tap:
The toe tap stopper does also but if the cap may unscrew from it before the entire stopper comes out. In that case, there is a nut that is now exposed and can be accessed to unscrew the assembly.

If either of these is "spinning" without unscrewing, the threads are stripped and you would need to exert upward pressure while unscrewing in hopes of uncoupling this from the bath waste. If that doesn't work you would have to unscrew the bath waste flange from the drain pipe.
This will require access under the tub. I hope this answer the question for you. Thank you for using FIXYA. Jeff

Okay, remove 2 phillips head screws at lever handle/overflow.

Pull firmly with much effort and bowing the connecting rod a bit.

Up will come a heavy duty spring on the end of the rod.(prolly a big slimly hair ball too!)

Hope you get the spring, cause that's what works the drain stop.

If spring doesn't come out you'll have to "fish" it out.

Clean everything up real good and flush drain good also now.

The "Secret" now is to put the Lever,rod and spring assembly back in and replace screws and get the lever flipped to the left BEFORE you put the Drain Stop in.

If this is a trip lever waste type of drain it can be adjusted, Remove the 2 screws that hold the adjusting lever, this will allow you to remove the stopper. Clean the stopper of hair and sludge and replace. This will usually fix the problem. If not then adjust the linkage for the stopper.

If it is not a cable operated drain stopper, most have a knurled push pull knob on the top of the stopper. This knob should twist off to the left exposing a screw slot in the middle of the stopper. Using a flat blade screwdriver turning left until the stopper is free. If it is a cable opperated stopper, it is best to get a pro to replace it. If the cable is damaged and needs to be replaced, the tub will have to be pulled to do this job.

how do you remove bathtub drain stopper. manually screws open--won't twist off--no screws apparent????

under the decorative knob there is a screw,this is what holds the stopper in place.if not it should just unscrew.
