Flat lid leak
Step 1. Identify exactly where the leak is occurring by performing a leak test on an empty Fermzilla.
Close the butterfly valve (if using a conical Fermzilla) and place the lubricated lid and lid collar on the
Fermzilla. Hand tighten the lid collar and then pressurise the Fermzilla to approximately 10 psi using
either CO
2
or compressed air.
A leak test can then be performed one of two way:
1.
Spray or sponge detergent or stellarsan solution onto the lid of the Fermzilla making sure to
cover the entirety of the lid including underneath the lid collar, the entirety of the lid and
around the PET caps/carbonation caps. Look for the formation of bubbles indicating a leak.
2.
Invert the Fermzilla and submerge the lid in a bucket of water, sink, bath or pool. Look for
any bubbles forming in the water indicating a leak.
If you identify a leak in the lid then follow the steps described below:
Step 2. Remove the lid from the Fermzilla and inspect the o-ring for any signs of damage including
cuts, burs or scratches. If the o-ring is damaged replace it with a new undamaged o-ring Part
KL14267. Also inspect the lid for any damage while the o-ring is removed. If the lid is damaged
replace with an undamaged lid Part KL11402.
