Reservoar like Tank-O-Matic (work in progress)

[trodas]

LANjack - now I understand your need for 100 ports

Holst - I was not that surprised at all by the crack Remember, the Tank-O-Crap got 5mm thick tube and still cracked badly... DD res got only 4mm one, but seems the material is slightly better. At least mine works well now
I used plastic barb - I was aware that at high temps, differences in expansing rate could made a problems. I find that the tape did not help me at all, the NPT thread is self-locing and work w/o the tape as well. But I discover this in my res, the DD one I used with the tape, as it come.
And one more thing - "statical" test for leak did not prove a thing. You got to test the thermal cycles, eg. from 20C make your water 60C and then back and repeat 100x
(be prepared to buy new res then )
