Name of a vacuum water based hanger-extender
I’ve been experimenting with rod extenders and water pumps with pretty ok results. The standard extender are not very comfortable, so I was looking for alternatives. I have found a couple of months ago an interesting system. Unfortunately I cannot find it again. So, I wonder if you know the name of a hanger/extender which is based on vacuum/water system. I cannot recall the website anymore, but on their website, you were able to see a video with a hanger that kind of looked like LG hanger, but they used water in the head chamber. I think it was somewhere from Eastern Europe.
