Okay, moving on from grey water to black water, or rather getting "water"
into the cistern.

Does anyone have any practical experience of how much head of water you
need to refill a toilet cistern from a water tank. No Pump.


Sounds to me like a case of simple gravity feed.

Yes. Looking for ideas on refill times and how far above the top of the
toilet cistern I need to place the mains top up float valve.

??? You asked about filling the cistern from your tank.
