For those teams still using the white Clippard volume storage tanks from last year, you should read the FRC Blog linked
here dated January 30, 2013.
There are very specific instructions included on the safe installation of the fittings on these tanks. I'm not sure if Clippard will still replace them, however I personally know the Clippard family and company and I know they want to protect the safety and health of every
FIRST participant, spectator and volunteer.
We currently use two of the new black vst from Clippard and are very pleased with them.
