After the high-pressure pump suddenly started making a humming sound, the conductivity of the water coming out increased from 6 to 50. Experts, please come in. The pressure of the security filter is normal; there is no pressure on the raw water at the control panel, and there is a significant difference in pressure before and after the membrane. In the RO2-1 arrangement, during backwashing, a small amount of water flows out from the pure water port in stage 1, while stage 2 shows no issue. Gentlemen, please help. :handshake
Why isn’t anyone answering? Prop it up by yourself

I’ve encountered this situation too; it was due to a broken spring in the check valve of the intermediate pump. It is recommended to perform a membrane leakage test for each membrane!
If you haven’t encountered the above situation, you can consider that friend’s advice; it makes sense.
What’s the result now, OP?
The first-stage RO membrane is clogged (deactivated).
It’s difficult to clean. Can it still be cleaned?
It is likely that the membrane has been damaged; it is recommended to conduct a water production test using a single membrane. This is a simple procedure – all that’s needed is an air supply hose, a plug, and a portable conductivity meter.
Agree with the opinion above. . Check whether the pump itself is damaged. Membrane damage may simply be due to a problem with some components (as it is a physical damage), but if there is a problem with the high-pressure pump, it becomes more troublesome (although the probability is low). It’s also worth mentioning that the pressure difference between the pre-membrane and post-membrane areas is quite significant, which is a bit strange.
