Vacuum Leak

Hi, I have a fluid art challenger system running against our pond. I
suspect I have a vacuum leak somewhere since the pump starves for
water after about 10-12hrs. Any pointers on how one can diagnose the
problem? No apparent water leaks while the system is running.

TIA

Welcome to rpm.

I have no real wisdom for you. You can try some water on the supply
side joints and see if it gets pulled in. You could also have the
pump pull directly from the pond to see if the unit itself leaks. Do
you see bubbles where the water exits the return?

Are you sure that the supply line isn't getting clogged/blocked by
something? How soon after the pump has one of these episodes does it
"bounce back" and work properly again?

wow what a filter..if its not leaking i would think the suction end of the system ....plug the intake line,or lines.....get a plumbers drain king blow bag that you hook on a water hose,and it swells up in the pipe......put that in the outlet of your system and turn on the hose if you have a leek it will show up.............good luck ....
