On the end of the valve cap there is a black pip, this pip is pushed upwards and held in place when filling with water, this will also stop any water from coming out. Slide the flaccid penis into the pump when filled with water and release the black pip by taking your finger away prior to pumping.

To release the pressure you must first turn the valve cap anti-clockwise as far as it will go to unlock it. You can then press the cap down to release the pressure. As a backup, forcing a finger under the bellows pump where it meets your body will release the pressure, but this should be used in emergency only as constant use this way may damage the comfort pad.

This is often the case when you first start using the VaxAid as blood is being forced into the erectile chambers and blood vessels and they disappear after a few days. To avoid this:

• Do not over pump and pump slowly and evenly to allow your erection to grow gradually.
• Start with one erection to begin with and once full erection is reached release the pressure. Only start doing repeated exercises after several uses so that your blood vessels can become accustomed to it.
• If the problem persists, stop using the VaxAid for a few days and then start again. If you are in any doubt consult your doctor.

No (unless you are also using a VaxAid erection ring in which case go to the next questions. Water acts as a natural lubricant and cushions the penis making for a more even erection and this is why using water instead of air to exercise the penis is considered far superior.

Yes and many men do, there is no need to use any lubrication as water is self lubing, and self sealing, the erection ring is designed to go onto a flaccid penis and the hydropump erects you through it.

The bellows pump alone supplies maximum negative pressure in water but if you find it easier with the hand ball pump then the answer is yes, and you can use the hand ball pump with or without the hose connector.

The idea is to exercise the penis and this is best done by fully erecting and then releasing the pressure two or three times over a 10-15 minute period. If you choose to leave the hydropump on when fully erect, do not exceed 15 minutes in any 24 hour period, to assist you in the shower a shower strap accessory is available from the website.

The gauge on the vacuum tube is designed for you to monitor your erection. Some men prefer not to see this when using the Vaxaid, so you can find the best comfort position and then swivel the bellows pump so that the gauge is visible above or out of sight below.

The comfort insert provides extra comfort on the pelvic region when pumping and also to prevent the user's penis getting in the bellows when pumping. In either case, the use of the comfort insert isn’t mandatory and is down to each individual's level of comfort/personal preference.

Provided you have the strength to turn and depress the cap valve to release the pressure then yes. If not you may need help when using it. Also:

• The VaxAid is designed to withstand shocks and undergoes extensive drop tests from one metre high onto a ceramic tile. So if you accidentally drop the VaxAid in the bathroom it should incur no damage.
• The VaxAid also has roughened surfaces on the outside to improve the grip when pumping.

You can use the VaxAid daily as part of your washing routine, although two or three sessions per week should suffice. As for it being safe, leading urologists say it is not only safe they recommend regular use and over extended periods.
