Replacement PET Tank for 55L FermZilla.
Normal wear and tear may lead to stress marks or other potential points of failure when the tank is used under pressure. We recommend visually inspecting the unit for signs of wear every 6-12 months, and conducting a hydro test every 2 years. The hydro test process is simple:
Fill the tank to the brim with water
Replace the Red PRV with a PRV rated to 4.5 BAR or higher
Pressurize the tank to 4 BAR (58 psi)
Check for leaks, then replace the Red PRV when finished
If leaks or potential points of failure are found, replace the tank before you continue using pressure with your FermZilla.
In general, we do not recommend leaving products like PBW or StarSan soaking in the tank for more than an hour. Extended soaks have the potential to degrade the PET material and shorten the lifespan of the tank.
