I have a home made reverse osmosis and di system in my van and want to shut it off automaticaly. I thought about installing one of those ball and cock fittings in my tank like a toilet, but have relized that would only shut the pure water off and not the rejected water off. Is there a way of shutting tha pure and rejected water off together?
