The issue is the support for the gasket assembly. It’s basically a plastic puck that the valve and gaskets attach to. The issue is one of the screw holes [that the valve attaches too] is stripped, so when the pressure reaches a certain point the valve moves up a little breaking the seal and filling the inside with water.

I can get a new one for ~$14 CAD, or I could attempt to fix the screw hole with some wood glue or crazy glue; however, it is a high pressure seal that is used for making things that I’ll drink. It won’t come into contact with the water though, unless it leaks again.

I think the cheapest option would be to inject some wood glue (which I already have) into the hole, drill out a pilot hole when it’s dry and reassemble. It would be water proof and strong, but still might not work correctly. I could also use a bit of crazy glue but that might be a bit too fragile and could pool on the bottom, blocking the screw from fully seating.

…I mostly wrote this for myself to understand my options better, but decided to post anyways to see if any of you peeps have a better idea or experience with problems like this.

Here’s the part:

*I bought the part. Thanks y’all haha

**I also tried to see about glueing up the screw holes just to see if it’ll work, but the insides seem to be full of degraded plastic. Gross! I think the whole thing is degraded and needed to be replaced any way. I already replaced the o-ring that goes in it because of that issue, so probably the same thing with the puck.
