Over at the sewer list (
http://www.swopnet.com/engr/mail_lists/sewer_list_info.html ) there is a discussion about entrapped air in pipes. To search the sewer List, go to http://www.swopnet.com/engr/mail_lists/sewer_list_searches.html

I'm not sure if you have to join the list to be able to retrieve searches via email command.
