What are the recomendations for balancing the two intakes? The skimmer has
1.25" line running to it and the bottom drain has 2" pipe running to it. The
skimmer does not work unless I restrict the bottom drain which is easy
enough with a manual valve. Is there a valve out there for ponds that has a
variable venturi? This would allow the 2" line to be restricted and adjust
itself as needed to keep proper flow.
