Pond emptying after 2 hours of running waterfall
We need help in diagnosing and/or repairing our waterfall. The pond completely empties after running the waterfall after 2 hours. Any thoughts ot suggestions would be appreciated!! We have tried rebuilding it and using the foam sealer stuff. We have also gone through a lot of the diagnostic stuff that is commonly suggested when looking for leaks, but we do not seem to be getting anywhere. Just looking for something we may have not thought of.
