re flushing membrane
 

Hi there This is my understanding of flushing the membrane Just before your waste water moves away from the body of the filter Should be the yellow hose there is a white thing clipped on to the filter it has a black handle . the handle should be turned across the direction of the pipe to make ro water you would think your turning off the filter but thats how it works. to flush the membrane turn the black handle the same direction as the pipe let the filter continue to make water for about 20 minutes threw out that water . now turn it back across the pipe do this once a month

That is also what the instructions say....the reson I was confused is because my unit doesn't have that black handled thingie, it has the metal turnie one.
