I bought myself a Christmas Present and have been playing with it.
Yesterday after playing as I've posted; I once again drew down the chamber, closed the valve and shut off the pump. I figured that I'd see if it would hold vacuum overnight. When I arose I found
ZERO VACUUM!! :thinking:
I again drew down the chamber but this time it wouldn't evacuate. :banghead: When I shut off the pump I could hear the hissing of air so I went inside to make a soapy water mix so that I could see where the leak was. BUT THEN it dawned on me that it was A Lot Colder in my attached garage then it was when I first started playing with the system (about low to mid 30's F)
So I put the spray bottle aside and brought the unit inside and let it warm for a couple of hours and then tried it once again. And
BINGO! All was working perfectly.
I believe that due to the close tolerances that the cold had allowed some of the parts to 'shrink' and had allowed for the gaps that created the loss of vacuum.
You learn something every day! :tu
