Use gray to flush black
Related to my previous post, has anyone tried some kind of pump to use their gray water to flush a toilet ?

I have a separate pump and filter for the grey side.
Anything "special" about the pump and filter you are using ? Could you share the brand and model numbers ?
The filter I use is a "bowl" filter with an element that is more like a screen then a filter which is good for catching hair and can be cleaned. The pump you will use should almost be equivalent to your own fresh water demand pump but make sure it cannot out-pump the freshwater pump. I have check valves in my system but in any event I do not want the grey water pump to be able to overpower the fresh water pump head to head, just as a further safety precaution. Like the fresh water pump, the grey water pump should be a demand pump.
I can look for model numbers for you tomorrow.
