Up to what point can I submerge my PH probe without damaging it? The reason i am asking is because i have the probe placed in my return section of my sump and when I turn the return pump off for whatever reason some water siphon back in to the sump and water level rises a bit so I am worried that when water rises it would damage my probe if the level is too high

anyone has any idea? is there a maunal for the probe online i can check it out?

You don't need to worry about submerging it.
The only thing you need to watch is if the bulb gets exposed, but that would be the opposite when your sump goes below normal.
