Measuring Water Quality
Sterility is one aspect that is not mentioned here for obvious reasons (brevity). There is a way to safely, cheaply, and effectively test for water quality and even a beginner gets it right. And it...

Not for an RV -- RO waste can just be plumbed into the water holding tank. Zero waste.
I've asked it before when this "solution" is posed. exactly how would you re-plumb a separate holding tank for the recovered water under these conditions? If you keep dumping "dirty" water back into the one holding tank what is the efficiency?

AFAIK, most of the reverse osmosis filtering systems are returning the same water that came out of the tank, back into it. The elements that are removed in the filtration process are captured in the media of the filters.
if the filters take out these impurities, why is the RO system required. if they do keep returning waste water to the holding tank, eventually it will end up with some highly contaminated water which lessens the efficiency of the RO system. this is one of those "helpful hints' that various speakers at RV clinics recommend which fail under close scrutiny. yes, a small one for drinking water at the faucet with the waste water dumped back to the fresh water tank would work. a whole house system won't without tremendous waste.
you could of course install a separate "dirty" water tank and have it supply the toilet and outside shower or some such by redoing the entire water system of your RV.
