Hey, may seem daft but I wondered whats best after you've produced your water for the day or week. Do you close off your valve tap on the ro to stop water leaking about? or leave it open to drain out? Coz if you disconnect it all to bring in from the cold for some time, couldnt this kind of dry it out and mess it up? I dont know, its why I ask as there dont seem to be many instructions with them.
