Mine is running for 8 months now. Still looks and feels like new. No cracks at
all.
Did you use Polyethylene? The rigid stuff like you would use for an ice maker.


I used the stuff from home depot / lowes - same stuff diff price...

All i have to say is i just lost a full tank of co2 because of the crappy
tubing they sell - you get what you pay for. It dried out *since janurary
when i put it in* and cracked and leaked over the weekend while i was away.
