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?
