I have akohler bath drain that seals/drains simply by pushing down on the gasketed spring-loaded chrome stopper. The drain is clogged with hair but I can not figure out how to remove it and snake the drain?

This seems like a system which is proprietary to them, so best to ask their Support staff

You could have retrieved the old spring with a flexible magnetic reach tool.

The rubber seal on your washer and similar front loading washers is a relatively easy repair. The seal is held onto the front washer panel and the fixed inside washer drum with separate spring-loaded rings that are reusable. So, don't throw them away! You need to remove the front ring from the front panel before you can remove the front panel. With the ring removed the gasket should be pushed into the washer; noting any drain holes, so that you can reinstall the new gasket in the same orientation. Once the outer ring is removed and the front panel is out of the way, you will have access to the ring holding the gasket to the drum. After the inside ring is removed, the gasket should pull off the fixed washer drum. You are now ready to install the new replacement gasket.

The amount of disassembly of the front of the washer is your option if it interferes with the installation. The door is usually heavy and it is useful to remove it from the front panel. Usually, a couple screws holds it in place. Removal of the front panel may also involve removal of the top of the washer and moving the control panel out of the way so that you can access the screws holding the front panel onto the frame of the washer. The locking latch may have to be temporarily removed but can be left in place if you simply push the front panel out of the way to have access to the inside gasket ring. It is useful to take pictures of each stage of the disassembly process to make sure your reinstall everything as it was.

Installation of the gasket starts with reattaching it to the fixed washer drum flange and then replacing the spring-loaded ring to hold it in place. Make sure the gasket orientation matches the original position. After the gasket is attached to the drum, you can now reinstall the front panel. If you unscrewed the latch mechanism when you took off the panel, now is the time to reinstall it as it can be manually held in place behind the gasket. The door can usually remain off the front panel until installation of the gasket onto the front panel is complete. Now bring the gasket forward and reinstall it on the flange of the front panel; secure it in place with the spring-loaded ring. Your gasket is now reinstalled. Simply reinstall the door and your repair is complete.

Tools needed include a blade screwdriver to help pry the rings off the gasket seal and one or two specialty screwdrivers (usually Torx or Philips) to remove the front panel.

The gasket is installed on the outside of the tub. Use plumbers putty under the male end on the inside of the tub as it stays permanantly flexible and will not mildew like silicone caulking can. Do not silicone or use plumbers putty on the gasket. The gasket will seal nicely under pressure from the connections.

Spring loaded chrome stopper will not stay down to fill tub with water.

No, not without sealing, I mean clogging, the drain. Do you know exactly where the leak is coming from? I would suspect that the water is getting around the drain, instead of down the drain. The visible part of the drain should unscrew from the part that is underneath. That bottom part is likely permanently sealed to your drain plumbing.
You may be able to easily fix your leak by:
#1 Unscrewing the visible drain top.
#2 Replacing the washer under that top. This will seal your tub to your drain. All water will then be forced to flow down the drain properly.
#3 Screw the top of your drain back into place WITHOUT folding or wrinkling the new washer.
Good luck

There is a couple of fixes. If it is the spring loaded kind, you can unscrew it, they make a replacement for it. Its the whole piece old out new in. The second is to istall the old trip lever style.

The seal for the drain is leaking. It is either the drain itself or the seal beneath the drain. If it is the seal beneath the drain then you will have water going underneath the whirlpool and causing damage; if it is the drain itself simply replace the drain as it's seal is either broken or worn.

It could be the pressure on the drain isn't allowing the rubber around the drain pop up to come unlodged from the floor of the tub. I have ran into this problem a few times. the best way we found to take care of it was to install a push pull type drain assembly or try and adjust the drain pop up so it pops up higher allowing the rubber around it to break the seal and start to drain. take some pictures and post them i might be able to help more

Chances are that the drain assembly was not part of the tub but a 'generic' plumbing part. Is this pop up drain the type that you push down and it clicks closed and push down and then it pops up? It unscrews from the drain fitting and you can get a replacement at a big box store. A better pop up replacement is one called a Rapid-fit. It drains faster.
