Just put in a second 2" water line, the grey pvc conduit has worked great and with the bell ends you don't need separate connectors.
I disconnected the three 1 1/4 inch flexible pipes because they are prone to air locks.
The two waterlines are siphon fed from above the waterfall and travel 300 ft. to the pond, one is elevated all the way to provide a continuous even down slope, the new one runs along the ground and will be insulated to hopefully run thru the winter.
The elevated pipe supplies 60 gpm, and the ground pipe 50 gpm.
The price of 2" grey PVC conduit has increased from $3.50 to $4.50 each, but is still a good buy for running larger water lines.
The new line has a white pipe at the end so I can tell the difference at a glance.
