Following the implosion (with a loud bang ;D) of my brothers bin, he immediately constructed a safety valve, that opens when the under pressure in the bin, du to blocking of the entry hose, should become dangereous.
Attache the pics of the valve construction.
Finding the strength of the spring is by just trying different settings.
Simple design. Very good solution.
Thanks for sharing.

Yes, indeed it does look simple and easy to place on the top baffle! Looks like he found a quick solution.
