SaniAccess2 2-Piece 1.28 GPF Single FlushElongated Toilet with .5 HP Macerating Pump in White

A:  This kit comes with the SFA model 081 macerating pump. That pump has a tap to receive gray water on only the one side. The tap on the other side is fore the vent pipe. The vent tap cannot be used to receive waste water. However SFA Saniflo does produce and Home Depot does offer kits that use other model macerating pumps that do have two taps rather than one. For example if you look at the brochure for the SFA 082 pump you will see it has a gray water port on both sides. I think your best bet would be to use a different model that better fits the application.

A:  As a plumber questions like this confuse me because I know from experience that every job is different. Therefore I can’t be definitive. Generally speaking you will need three things. First a water supply line to the toiler. Second a waste pipe and a vent pipe. These two pipes take the waste and sewer gas back to the main waste stack pipe. Third you will need a power supply for the pump. An actual stock list would depend on what you already have on site and the plumbing code in your state.

It you open the specification sheet you will find a rough in illustration of the pump. Note that the bungs to receive the drain lines from additional fixtures are mounted up high on the unit. This is find for a lavatory sink. But this means you would need to elevate the shower significantly high so that the water could drain to the pump via gravity. For this reason people typically use one of the Saniflo models that have a tap for the drain line that is low on the pump. This greatly decreases the height to which the shower needs to be elevated. For example compare the rough in for this model to that of the model 082 pump. See Home Depot SKU 204253707. If you put this number in the search block on the Home Depot site it will come up.

And it, at the same time can pump up to 150’ horizontally. It also contains an illustration of the pumps performance curve. This is a graph that shows the pumps performance at different heads.
