Hi,

I've attached multi water level expansion to my RA, and the problem is that it does not hold the values. I've calibrated the water levels for all the tubes and at first they are showing normally ~70 percent and after couple of hours it goes down to 0 percent. I've tried to put tube in still water - it holds the level, but in moving water (sump for example) it is not holding. Any suggestions?

Make sure no air is getting in to the tube.
In moving water there maybe some air or air bubbles getting in.

Ok, I'm bit confused. No same happened where there are no water movement, it went down to 0.

Sounds like a slow air leak. Silicone the joints on the PVC.

After couple of days it stabilized and now working perfectly
