Hello,

I recently bought the starter kit for VI. I follow the instructions in the video and I am getting a vacuum pressure of around -27.5 but when I clamp off the bag between the vacuum bag and the vacuum chamber, the vacuum gauge goes immediately up. Why is this happening? In the video it stays where it is. Is there a leak in the vacuum chamber? do you have any tips how to check this? many thanks

Hello,

I managed to find a leak at the connector of the catch pot, this was causing the gauge to go up after clamping off the bag;it is fixed. Since I had a leak in the bag too I am planning to do the process of sealing again very carefully avoiding wrinkles, fibers between the bag and the sealant tape etc. I was wondering, isn't it easier to use two rows of sealant tape around my mould instead of one for better sealing/results?

many thanks for the tips!
