So i have a vacuum valve fixed on the housing. After pumping and creating the vacuum the green light flashes and if checked both, the front and the back are totally sealed. Even then there seems to be a very small amount of water that seeps in ??? Is there some reason or am i vacuuming extra ? Even after the minor leak both the front and back are secure.
I use the leak sentinel.
Any help on why would be much appreciated.
