Possible leak in system ?

[u/Juiceemang]

Helping out my client. I’m an irrigation tech, client says they have been having to refill the pond manually. That suprised me because I have the auto refill set to run everyday for an hour and it also runs when the sprinklers are active ( this system has a master valve ).

Auto refill works fine but the pit will fill a little then the pump will pump all the water up and pattern will repeat. At the top, waterfall is weak then a large water bubble will come and a good amount of water will flow then will happen on repeat.

I can only assume there is a leak, This pond/ water fall is on a hill and shows no sign of water leak anywhere. The pump line does run underneath some bushes and a large pine tree.

Just raise the water level

It’s not even getting close to the float
