RO/DI Membrane question

[whatcaneyedo]

There are some other alternatives you may want to consider. I've seen systems available which run two membranes for much less waste and others which return the waste to your hot water tank. If I had the room I would install a large plastic drum near the laundry machine and use all of the waste water for laundry.

I've been using RO/DI since 2005 because it gives me complete control over what goes into my tank. Think of it as risk management.
