So many questions on the reverse osmosis usage. What kind of flows do you get from it? I get the impression they convert water very slowly so it's not like an instant open tap. For example could you connect to a dish washer or is it only a reservoir for drinking water. What is the water waste like, as in how many liters are you spending in the membrane cleansing versus actual drinking water? What kind of material is used for the tubing and containers it uses? I am a little be sceptical of using flexible tubing (usually flexible because of plasticizers) to then feed and accomulate water into a reservoir.
