Collection in an open (unpressurized) vessel simply requires placing the end of the permeate tubing into whatever vessel you want to fill with water, such as plastic water jugs. You will need to manually turn off water flow to the RO system when the vessel is full. The obvious major downside to this method is that the vessel will overflow if it runs for too long. A simple solution to avoid problems in that case is to place the collection vessel in a sink, in a tub, on the ground near a drain, or outside (weather permitting). | Collection in an open (unpressurized) vessel simply requires placing the end of the permeate tubing into whatever vessel you want to fill with water, such as plastic water jugs.

Setting a timer is a good idea since it can predict when the vessel is full very accurately once you know the production speed of your system. | ||
If you prefer to have the system shut-off automatically when the vessel is full, you can use a dedicated vessel with a float valve installed. The float valve will shut off the permeate flow when the water fills to the level set by the valve (similar to how a toilet tank works). In this setup, an automatic shut off valve (ASOV) is also needed to shut off the flow of water from the feed water supply line; otherwise water would continue to flow down the drain after filling stops.<ref name=bhfaq/><ref name=screwy/> Additionally, a check valve is needed to prevent backflow through the RO membrane.<ref name=buckeye>[https://www.buckeyehydro.com/content/3_Stage_RO_System.pdf Understanding and operating your new reverse osmosis system (premium series RO system instructions).] Buckeye Hydro website.
