Drain Considerations

Since a toilet drain pipe is fairly large, it must be installed between floor joists. The strength of the floor must be evaluated to verify that it can maintain the weight of a toilet or it may need to be reinforced. The location chosen must also provide sufficient clearance from all nearby walls for the size of the toilet being installed. It's critical that the pipe has enough downslope for the flow of sewage and the vent pipes are in the proper location for the system to flush correctly.

Cost Factors

An experienced plumber evaluates the location and determines if the floor needs any repairs or modifications which can increase the final price. Installing a vent pipe, if necessary, requires additional materials. If the pipe requires a special route or extension to achieve proper flow, the extra hardware and labor may add to the cost of the project.

Consult a Plumber

Due to the highly technical nature of the installation, most homeowners turn to an experienced professional to install toilet drains. In many areas, local codes may require that pipe installations be performed by licensed plumbers. The expertise of a professional can help the homeowner avoid the pitfalls of an improper installation.
