Warning for RO-only users

[Slick Fork]

I've read before that RO systems really don't like the on/off cycle and do much better if you can do larger batches at atime rather then a litre here and a litre there.

I fill my top off container once every week and a half. A little more labour intensive, but I feel it's better for the RO membrane and better for my piece of mind as there's only a finite supply of water that could go into my tank if there's a malfunction.
