Hello,

I´m with difficulty to make total vaccum.

I´ve tried 3 times, with 3 diferent moulds, and never achieved total vaccum, there´s always a leak.

I´ve checked the gum tape several times, and nothing.

So i´ve tried with a Trough Bag connector at the vaccum line, and  the feed line without connector, only the pvc hose with gum tape.

The result was the same, so i decided to make some tests.

First test:

With the Trough bag connector closed, i´ve switched on the pump, and when the gauge indicator got to the end, i´ve closed the pump valve, and then switched off. The gauge indicator moved, so there is a leak somewhere between the Trough bag connector and the pump.

There´s a few fotos taken with 2 minutes between them:

Second test:

With the Trough bag connector closed, i´ve switched on the pump, and when the gauge indicator got to the end, i´ve clamped the vac hose between the Trough bag connector and the catch pot, closed the pump valve, and then switched off. The gauge indicator moved not so fast as the first test, but moved, so there still´s  a leak.

There´s a few fotos taken with 2 minutes between them:

I don´t know what´s happening, if someone know, please give me a help.

Another issue: When i connect the vac hose to the silicone connector, i´ve got to cut it to be more thin, otherwise the tube won´t fit in the hole with the bag thickness.

Thanks,

Pedro

Hi Pedro,

First thing to do is to put a clamp between the infusion and catch pot, now pull full vac against the clamp and close of the pump. If this holds vac for 30min then you know its not the pump, catch pot or anything on that side of the infusion. Also put gum tape around the hose barbs on the catch pot and pump and make sure the rubber seal inside the nipple on the catch pot lid is well placed and that the screw cap over the hose is tight.

Next I would say to rather use the silicone connectors, when you breach the bag to place the hose into the connector you should push the hose through the bag and then into the connector, only the hose should be in the connector and no bag, as this could be problematic...

From what I can see in the pics I would say the corners of the mould inside the bag also look very sharp and could be piercing the bag?
