I have an issue with our Ro System. The other day the booster pump was left on while the water to the RO was shut off and now there's little to no pure water going through. We acquired a new booster pump but there's still lottle to nothing coming through. Water to the drain is flowing as it should and the water being filtered in the pre filters is fine its when you get water going into the RO housing there's water coming out the drain but not the pure outlet. Could the pump have caused damage to the membranes in any way?

Have you got a flush valve on the ro and is it turned the opposite way to it should be

The flush is turned where it should be but the pump sounds like it's air locked.

[Mr.G]

have you tried running it upside down, might help to clear airlock

No I haven't, I'll give it a go.
