    Not going to happen. Bigger hoses and better quality stuff is going to speed things up IMO. If someone finds hoses that will hold a vacuum that would be a great find. I might feel remorse from the manifold purchase but you shouldn't with the hoses. If you didn't have bigger ones already it is going to speed up the job. If you rig your rig for isolation of the hoses, manifold and pump on a real system you should be much happier with what you have there. If you plan on following the "rules" to the letter you will be happier listening to the pump. If you know your pump I believe its a good indication of how you're doing. Start on a MO system then go to a poe system if you want to be disappointed again

    What is the purpose of a manifold like that when a simple tee will do? You should have valves at the service ports that can be used to isolate the system and vacuum gauge from the pump and hoses. Seems to me you are just adding leak points unnecessarily.

    No, I've been using a Yellow Jacket 69075, and vacuum tree, since 2007, haven't seen the need to buy a new vacuum gauge.

    I do wish my 13 year old vacuum pump would die, so I'd have an excuse to make my boss buy me a TEZ8 though.
    If more government is the answer, then it's a really stupid question.

    We could probably arrange the death of your pump....for the right price.

    Check out my crappy vid. It will give you some info and show you a few popular Gauges installed on the same system..

    Last one

    This is one relates to your issue the most.. After I allowed the pump to run for an adequate amount of time the micron reading did not rise as high. (above 1500 microns)

    So I hooked the whole rig up to two Recovery Cylinders and ran the test again.

    Then I went and watched the Super Bowl. When I came back, over 10,000 microns.

    Dave before I watch are you still trying to hold a vacuum with hoses in the circuit?

    I noticed in the first video is that you are valving from from the manifold and keeping the hoses in the system. Permeation from the hoses is what is killing you! You should be valving the tanks off!
    I also noticed that something is amiss with the time it took to reach your desired vac. I would think to start with your pump.

    I have been noticing similar issues last season with my dvn22 micron gauge . i actually use the 3/8 hose directly from vac pump to suction side of condenser valve with appion core tool hooked up, then the micron gauge hooked directly to another appion core tool on high side of condenser

    So after reaching desired micron reading i close ball valve on suction side and wait.. all seems fine but after i then close ball valve on micron gauge core tool it immediately rises and fast,, makes me think theres a leak in the micron gauge..

    I spoke in depth to aJB engineer at the expo about this and he says he doesnt think theres anything wrong with gauge long as it doesnt rise past 9000/1(whatever that means in English ) and says its normal for some rise due to moisture etc just like a system/.

    im not sure i believe him but this thread along with my issues is making me not trust this micron gauge and others ive owned in the past.

    feedback?? letys continue this conversation as it can help a lot in the field..the good thing is he told me to test with a tank like this thread suggests and see what the actual rise stops at, if i still feel its faulty he promised to pay for me to send it back and they will re calibrate and test for free even if its out of warranty..

    I would like to know what would possess someone to buy a manifold like that. What purpose do the gauges serve in a deep vacuum? Can you take them back?
