Is the coffee and wee wee compulsory or will it work with skipping these, I take it if your unit is very dirty then you have a cupachino and a #2???

The amount of times I have switched the RO on, start flushing it, then 3 hours later realise OMG, the RO unit is still flushing....needless to say the RO drum has got 1 litre of water in it and the swimming pool is almost overflowing.
