This is mi first post here. I,m new to composites, vacuum baging etc... Working on mi project and having some problems with vacuum. Pump is 3GSM bag is 1.6m long and 40cm. wide. I don`t have good vacuum, kinde of weak. Checked for ail leaks- thereis non. What the problem? Thanks in advance!

First, remove all pipework up to where you are measuring the vacuum and cap off/seal/turn valve off.

Thanks for reply! Today in the morning I think that I`ve found problem. Pump i brand new (first time in use) and no leaks in bagging or pipes, but i`ve realize what I did wrong, was very tired yesterday. I did extend plate on which I did vacuum bagging with another plate and I did not seal the joint So in was sucking up the air from under threw this joint. Well it was very first experience in vacuum bagging........
