If you have a bubbler pipe that is clogged with dead water, you can use a hose clamps to pull it back into the pipe and allow it to drain away.
To do this, attach a piece of string to the pipe using two or three lengths of string tied together.
Tie the ends of the string tightly and tighten the ends as tightly as you can, or you will have a difficult time pulling the pipe out of the clogged water.
The more string you use, the more difficult it will be to pull the pipe back out.
Another method is to put a large piece of plastic tubing in a water pipe that has been clogged by dead water.
This is also a method of draining the water out.
You should then wait until the pipe is free from the water before using the hose clamp.
