Bubbler or no bubbler

[dlynds]

Using koh as an electrolyte , is it nescessary to use a bubbler ? When I shut my system down, the water in the bubbler gets sucked back into the electrolyzer.

some people put one way valves between the cell and the bubbler. if you dont want a bebbler then you can have a blow off valve on your cell so if it flashes back the valve will open and prevent the cell from exploding.
