Water pumping

I tried water pumping for the first time tonight.
It is something that I had wanted to try out for some time but as I nearly always have showers I had not got round to it.

Instead of a heat-pad I warmed up in the bath with 10 minutes of plump bends and then started pumping.
I did not pack as far up the tube as I would from dry pumping and my length in the tube was short of my normal too.

Has anyone else had more success with water pumping?
