I am thinking of getting a RO/DI unit, but have some concerns about installation. Are these things generally easy to install and uninstall? I rent my apartment so I can't put a permanent fixture on the plumbing.
I have been using mine for months now, uninstalled. It is small enough that I can sit it on the kitchen counter, and hook it up to my faucet. When I am done, I unhook it and store it. Try to store it with water in the filters, though. Storing it dry will shorten the filter life.
Thats a couple of options for a temporary hookup. I personally used the faucet adapter for a couple of years with RO/DI setting in bathroom floor beside sink. I finally made a permanent install under kitchen sink recently.
