I am making provisions for installing a new toilet as the most upsteam item on the drainage line in a single story home. I am wondering if this is recommended or whether it goes aginst standards.

There is about 18 meters between the new toilet and where the sewer line drops underground. Within that 18 meters, several sinks, 2 showers and another toilet all connect into the sererage line.

Can the new toilet go upsteam of all of this considering I can maintain a good fall between the new toilet and the existing sewerage line?
