Let me be more clear, you do not need a tub to do what I am describing. I said get in the tub because that is the place of my house that if I spill water it is okay. This can be done just as well in a shower. Allow me to be more clear.
Stand in the shower or tub. Make sure your shower strap is attached to the pump device but not around your neck at this time.
Fill the cylinder with warm water all the way up to the rim, like a glass of water. You may get water on your shower strap. This is fine.
Get erect as you can and insert into the cylinder. This can be a Penomet or a Bathmate water pump, the concept is the same.
Pull the cylinder to your body and pay no mind to the water you spill. When you tilt the cylinder for the initial right angle you are bound to spill water. If your erection angle is higher than 90 degrees you need to have your erection as straight out from your body (mimicking 90 degrees) as possible. If your erection points straight up there is no way to effect a good seal with these pumps. You will have to hold your erection in place for the optimal angle while you pull the pump on.
When you are pulling the pump cylinder to your groin the bathmate has a valve you have to turn and press the switch. You have to have an idea of how much pressure you would like and then close that valve by flipping the switch and turning the valve to seal the water in and air out. Otherwise the pump bellow will do its job and push the cylinder away from you, inhaling air and ruining your seal. Instead of maintaining the physical force needed to effect both your seal and desired pressure.
Holding the pump cylinder with one hand bring the shower strap around your neck with the other. You will need the shower strap if you plan on moving around with the pump pressurized with water. Otherwise you will stand holding the pump for the entire duration and being basically unable to move.
*pro tip: prior to actually using the pump with water I recommend a dry run so that you can place the pump on your penis and know exactly how much you need to adjust your shower strap to your height before you have water in play. These things are very long. Slack in the strap will allow a pump full of water to fall, making a huge water mess and no productive PE. That way when you bring the shower strap in play it will be adjusted and ready for use and not require any additional steps or be an additional liability. This lowers the risk of ruining your seal when you’re actually using the pump.
This is the method I use to get my pump to seal. I do not use the bulb and hose, either.
