Connecting a GFX to a toilet drain is not going to be very sensible,
however, unless you heat your toilet water - makes the most sense when
connected to drains that might have hot water - putting it in the
blackwater stack just adds one more way to have a toilet flush make your
shower uncomfortable, and reduces the potential efficiency by reducing
the temperature differential across the heat exchanger.


Yes, there is no heat to recapture, UNLESS toliet supply is also hooked
to GFX heat exchanger.

The point to adding in the toilets is to make installation simple.
Locate the SINGLE sewer pipe in the basement that collects ALL waste
water, and insert the GFX into the pipe.

Running toilet water to the mix of effluents processed by the system
adds NOTHING to efficiency, but makes installation a BREEZE.
