All the air stuck inside the bottom of the system will purge immediately and air pressure will pull the blockage (mostly tampons mixed into cooking oil, roaches and chicken bones) through. Unfortunately because women are evil and their bodies are designed to be mechanically deficient, my sister and her friends would dump all their tampons in the toilet causing the entire system to stop until someone physically pops it out with an air compressor. This is done by opening the valve on the bottom and, using an attachment, pumping in 100 psi into a port above the blockage. Because all the trailers have fittings for this, it works pretty well without a mess. The mess then goes down to the main cleanout where someone has to then reach in and retrieve the big tampon feces and bone clump out of the pee/oil mixture.
On a normal holiday weekend this was done the day after forcing everyone to use the gas station toilets nearby until the jew motherfucker who owned it started charging for access, which is a warcrime. Everyone then decided to just pee on his propane tank as revenge, so he raised all alcohol prices by $1 across the board which is very evil for an unemployed impoverished trailer park resident.
It was possible to make an entire pool of feces and this was how things worked in the old days before the government mandated they stop dumping into an open cesspool because of malaria or something. There's so much toxic waste drums dumped there anyway it's bullshit but that was Jimmy Carter for you.
