The most unique aspect of my plumbing layout occurs on the ground floor, where I have two walls with plumbing. One of these walls has fixtures on both sides, which also complicates the design because this configuration does not repeat on the floors above. As a result, the supply lines cannot run directly up the wall, as doing so would interfere with the occupied spaces above.
To address this issue, I ran some pipes horizontally between the two bathrooms to connect back to the main supply pipes located in the wall that has fixtures on only one side. Out of the three types of pipes used, the sanitation pipe required the most consideration. It needs to be connected in a way that allows for proper ventilation to prevent stoppages. This involves running a pipe back to the trunk without a slope and without connecting it to fixtures, ensuring proper airflow, while also having additional sloped pipes to handle waste.
