The 18” extension pipe was designed with the idea to reduce time when installing our macerators.  It has an inner gasket which connects to the rear spigot of the toilet without any difficulty. Its sealed connection keeps water from seeping out once the toilet is flushed. Its ease of installation is the reason why installers recommend this accessory for any Saniflo installation. When using the extension pipe, the toilet bowl should be raised 3/8 inch for additional gravity flow toward the macerator box.

Extension pipe between toilet and macerator.18 inches long x 4 inches wide with a 5 inch bell.
