Pop up waste

[Sanjay29]

Have fitted the attached pop up waste.
The rod is connected. I can get the waste to seal with the lever. But when I try and drain the water, it does not rise high enough to let the water flow out quickly. It will let the water out at a very slow rate. I can use my fingers to raise the plug but that defeats the object.
Thanks in advance.

The plug will be adjustable. Lift the plug out and there should be a screw and locknut so you can set the height

Also the linkage is adjustable, need to make sure it gives maximum lift
