Different bottles are made from different materials and will produce different results from the Spatap. Select the correct bottle for your washing purpose.
The bottle or container you use will depend on your requirements for washing or cleaning. And how you use it will depend on whether water is abundance or scarce.
AS A RULE
Use a hard or firm bottle to action minimal water mode, or free flow mode. This bottle will flow controllable with the bung starting and stopping the flow of water when it is place in and out of the air valve.
Use a soft bottle or a collapsible bottle for a Shower. The softer the bottle the more the bottle will implode and force the water out under high pressure. Softer the bottle, the higher the pressure. These type of bottles are NOT suitable if you require a Tap mode as described above.
Experiment with different hard and soft bottles to find which one is right for your washing needs. All bottle are not the same and will give different flow rates and washing experiences.
A rule of thumb is:
1.25L bottle or smaller is good for a Tap
2L bottle or bigger is good for a shower
Some bottles are good for both
