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 pump is an Artis Model PDS1RV25, 40 psi max, draws 7.0 amps on 12 volts.
There was no visible information on the filter but it is shown below

Here is the pump and filter. The water flow is up and over. The lower pipe taps into the grey water tank about one quarter up from the bottom. There is also a low point drain on the lower pipe which is needed for winterizing -

Here is a close shot of the filter. You can see the screen -

Here are the valves used to select fresh or grey water for flushing. Grey feed is on the right, fresh feed is on the left. The blue pipes are the original fresh water supply. The valve on the right selects the water source. The valve on the left, along with the check valves, is used to insure that no grey water enters the fresh water system. Right now the valves are set for fresh water use -

And finally, this switch powers the demand pump and is in the bathroom. Normally left on, but if the pump starts grinding in the middle of the night we can quickly stop the noise and save the pump. Originally I wanted to mount all the valves in the bathroom next to the toilet, but there was not enough room. -

Hope this helps. Good luck -
