Hi I ordered VI Starter kit.

My Vaccum pump is working but It looks little bit out of order

It pulls vaccum until 90% well. but when it comes to 90% and about 5seconds later,  It's noise nevel is much louder. and it can't proceed more than 90%

I hope vaccum gage is not accurate.. but noise sounds out of order. The sealing is perfect (I onlt test with the catch pot and when I turn off the turn valve, there is no leak)





and when I turn off the vaccum pump without turn valve off, the air leaks from the vaccum pump quite fast. is it OK?

                 unscrew the connector & valve from the pump, clean the threads and put back together with PTFE tape...
