Sticking with the subject of Type II ducts: How do you prevent them from leaking all over the electricals in the pizza ovens after you are gone? Do you purposely use less water to clean the leaky pipes, use chimney brushes or avoid shooting water down altogether. My experience is that they have 45 and 90 degree turns in the chute, are held togther with screws and leak like sieves.

Whenever possible I tarp underneath the duct run.
As far as leaks after your done- between vacuming out accessible areas and letting the fan run to pull out the moisture it usually works out well.
The way they have put some of them together its almost impossible to tarp them because of the location meandering through the rafters or a wall or what have you.
In that case clean what you can and make note of everything that cannot be done and have someone in a management position sign off on it.
Type II's should not be installed anymore as far as im concerned. Every install should be air and leak tight.(thus taking care of the rivets and screws holding the crappy tin ones together)
This needs to be addresed at the next NFPA meeting for updates.
I also suggest that all Type II hoods with a range underneath be updated to a UL 300
fire system.
