Duh! Ive only ever water seal tested some vase cup type prints,no leaks there. An interesting task for an fdm printer. I wonder how a larger nozzle from the volcano would do?

I found this from stratasys. Even with a sealant they say 65 psi

Just so you know, the public water supply is not under all that much pressure. 40 to 50 PSI in most places and can be as high as 100 PSI in some. That being said I made a shower head once that had individual arms with holes in the end to create a vortex like affect. It was on thingiverse, not my design. Anyway I printed it with 7 perimeters just to be safe. Even with that it still leaked more water over it's body surface than it actually sprayed. Looked like it broke out in a cold sweat.

If you post process with a solvent you might get airtight, but 80PSI is asking a lot.

Puting large internal radius in will help. The hoop strength should be pretty decemt  especially if you make it nice and thick. Make sure to have your starting points on random, so you don't have a weak seam.

Be sure to gradualy raise pressure as you test to be safe. Plastic shrapnel is no joke. The link below will have more than enough info to get you going, also a great resource in general.
