Replaced RO membrane and now no water is coming out.

Well, I guess it's good to have it, even if it's not used.


Well... it's supposed to be saturated, not dripping water per se. If it was allowed to dry up, it could permanently damage the membrane.

But we're getting too far ahead of ourselves.

We've established that you installed the new membrane correctly.

It appears that you have the inlet tap water (red) line correct.

We're assuming you have adequate water pressure???

And have you verified that water flows freely to the drain when the reverse flush valve is open?

And what happens to the water flowing to the drain when the reverse flush is closed. Does it slow to a trickle?

Yes! Pressure looks good and water is coming out of the black waste line.

Next i would pull the blue line, the one on the left of the auto shutoff in the picture and see if water trickles out of there.

If so, connect it back and pull the blue line on the right of your picture and see if it trickles out of the auto shut off.

@AydenLincoln

Do you still have the old membrane?

Did you make sure the new membrane has the rubber seal (flap) is in the same location and orientation of the old one?

Yes it does.

Ohhhh! Did it come in a sealed bag? Did you notice if the membrane was still wet?

Do not know if that brand is sourced from DuPont but DuPont has improved the chemistry of their membranes and they now come dry.

There is a RO flush valve on the unit. Maybe you bumped it. Turn the valve the other way a see if it starts producing water. If not, turn it back to life it was…. This happened to me before…
