Could an argument be made for FIFO, using your old water first?

What happens if you switch your selector to draw from a full tank?

I have another troublesome detail to deal with. I have this tube that,
if everything works the way I planned, will be spewing out half a gallon
of fresh water a minute. Now how do I get it into the tanks?

I am thinking about plumbing it into the fresh water system between the
tank selection manifold and the fresh water pump. That way which ever
tank is active gets filled. By changing tanks I can fill them all from
one connection. On the face of it it looks like the ideal solution but
I am looking for any drawbacks.

Anyone want to shoot some holes in my plumbing? :-)
