Hi guys after some advice. I'm using all easy composites vac bag supply and pump.
I'm having major issues with bag leaks,  with the pump on its perfect but dosnt hold it once it's off,  and I'm not leaving the pump on for 2 hours lol.
Any way of checking and finding where the leaks are with any device. ? 
Also do you have to seal the hose onto the push connectors or will they be ok and airtight. ? 
Iv even tryed a flat bag and still leaks.. :s
I'm going to order the vac gauge,  anything other help would be grear lol..

Cheers

One big problem that people will face with bag seals, is that if U r using too Slippery releasing agent. Then the bag seal wont hold. Example with Flex-Z series releasing agents. if U r using number 3, its easy to get bag to seal. but 4, 5, 6 are hard. Those are just too slippery and it wont hold the vacuum.
