Performing a Leak Test
It is essential to perform a leak test whenever you plan to bottle any beverage using the NukaTap
counter pressure bottle filler.
A leak test can be conducted via multiple methods which are outlined below. It is a good idea to
perform both of the leak test methods to be certain the system is holding pressure and to avoid
using excess CO

during the transfer.
1.
Pressure decay test
Step 1. Hook your NukaTap counter pressure bottle filler up to your CO
2
regulator and gas
cylinder.
Step 2. Set the pressure on the regulator to 10psi by turning the adjustment knob on the
regulator clockwise
Step 3. Turn the gas cylinder off and leave to sit for about 10-15 minutes. Then check if the
pressure on the regulator has decreased from the set pressure.
If the pressure has dropped then this indicates that there is a leak in the system. The source of
this leak needs to be determined and fixed before proceeding.
2.
Bubble test
Step 1. Hook your counter pressure bottle filler up to your CO
2
regulator and gas cylinder and set
the pressure on the regulator to 10psi.
Step 2. Spray all connections with soapy water and look for the formation of bubbles. This
includes all push fit connections and connections between the regulator and CO2 cylinder.
Note: Do not spray any duotight fittings with phosphoric acid or StellarSan solution.
If bubbles are formed at any of these connections this indicates a leak which needs to be fixed.
Alternatively, the counter pressure bottle filler including all hose connections can be submersed
in water. The formation of bubbles in the water indicates a leak.
