Pond Leak: Will Turning Off Waterfall Pump Stop Auto-Fill?

Auto-Fill Behavior Depends on Leak Location

Large leak; pump turned off. Will float valve stop?

• Leak in waterfall/stream: Yes, water level in pond stabilizes → auto-fill stops.
• Leak in pond liner: No, pond keeps draining → auto-fill runs continuously.

Finding the Leak

1. Turn off pump; mark water level.
2. Wait 24 hrs. If level drops → leak in pond.
3. If level holds, turn on pump; if drops → leak in waterfall/plumbing.
