I don’t have a full package pump, but I decided to try indoor water pumping using cylinder space as a reservoir. In my case, I have at least an extra inch of tube space left after full pumped expansion, and I found that careful manipulation of water levels allowed mess-free water pumping.
With the pump disconnected, add some water to the tube. (This will be a trial-and error process, so start with an amount of water you are confident will be too small.) With the cylinder pointing generally downward, insert your unit and firmly press tube until you have a good seal. Maintaining firm pressure on the tube, you should then be able to lie down without spilling. With the tube pointing straight up - and a fair amount of your cock above the water line, you can then attach the pump line and begin applying vacuum pressure. If your dick is not fully immersed at the desired pressure, depressurize the tube, add a little more water, and try again. (Once you find the right water level, you may want to mark the cylinder for future reference.) You can vary the pressure on your fully immersed unit, as long as you keep an eye on the water level to make sure it doesn’t enter the pump line (unless you have a small additional reservoir attached).
Could be my imagination, but I think I got a little less length expansion this way compared to air pumping.
NOTE: This method is obviously not going to work for any one who packs the tube length-wise. But for guys who want to try mess-free water pumping outside the hot tub/bathroom, this might be an up-side of deliberately getting a tube a couple inches longer than your minimum requirement.
