Product Information

The Bottleshower™ 500ML - 2 Litre heads fits all narrow neck water bottles available world wide including Coke a Cola and soft drink bottles. Hundreds of bottles from around the world have been tested to ensure an acceptable fit and flow.

The 5 Litre version with silicone bung fits all commercially available bottles ranging from 39 mm to 42 mm internal neck dimensions. The individual shower heads simply twist into the top and when the bottle is upturned produces a constant pumped shower flow, no squeezing is required.

The Bottleshower™ heads work by using expanding air carried in via the air hole and tube to displace water in the bottle when it is upturned. This process works unaided and the bottle should never be squeezed. The black ‘O’ rings on the tapered neck are of varying sizes to ensure a perfect seal across the wide range of bottle necks available.

When inserting the head twist it carefully into place, never push it in using the palm of your hand or force it by hitting with any object. If the Bottleshower™ Version purchased comes with additional instructions read them carefully before proceeding.

When using the Bottleshower™ with the 2 litre and 5 litre bottles you may find that when first upturning them the flow stalls and a small amount of water escapes back down and out of the air hole, this is because the air travelling up the tube has not yet connected with the air already in the bottle, making it stall before the airline is clear of water.

IF this happens turn the bottle back up right for a second and then back again. Always try when using big bottles to get the air tube at the highest corner of the bottle to ensure a quick start to the flow.

TIP: As you insert the tube into the bottle keep your finger over the air hole in the shower head, this will aid the air getting into the bottle and avoid any temporary stalling of water.

Flow Times
There are two versions of Bottleshower™ you can choose from for showering or washing. Look on the shower head for the markings plus or minus. 

Plus Flowing Tap Head Bottleshower

Plus + = More water less flow time
(Long tube for 1.5 & 2ltr bottles)

Less Flowing Tap Head Bottleshower

Minus - = Less water more flow time
(Short tube)

Depending on the size of bottle you have available and washing needs these tubes can be swapped around.

When used for wound irrigation or burn treatment he flow and spread of the water ensures concentration on the affected area without damaging the skin making it more comfortable for the casualty and reducing the risk of extended scar tissue.

Flow Rate Running Times

Hundreds of different designs of plastic PET water bottles have been tested with the Bottleshower™ for fit and performance. Tests were conducted to give a multiplication guide that is honest but not scientific, tests used the readily available range of EVIAN 500ml, 1 litre and 2 litre bottles.

Guide Flow Time

POURED -    12 seconds - A constant continuous flow of water till empty
SHOWER -     1 minute 12 secs - Showerhead marked with a plus sign
TAP -               2 minutes  - Showerhead marked with a minus sign 
The above times are based on the Evian 1 Litre bottle. Other types of bottle may give slightly higher or lower times.
