Could any one who uses this system tell me what your waste ratio is to drain.
I used to have 70 to tank 30 to drain. Changed the robak and the ratio has fallen to around 20% to drain.
The only difference is obviously the new filter and I have noticed my mains pressure had risen. I now fill at 75psi and not 60psi. The drain tap is still set as before and fill time is still the same. Making water at 00.2 at start rising too 00.5 towards the end. Regard Steve.
