Koi Pond Plumbing

Outflow from the pump to the pond




















4 inch lines from the pond to filter and T to the outflow drain. Also the 2 inch skimmer line comes underneath and behind the main drain. New valves to the left. The grey area to the right is the gunite that had to be chipped away to expose the existing drain lines.





Lines from the filter and pond to the outflow

Showing the trench and  lines between the filter and koi pond on the right. Drain coming out of the filter was newly created and installed, prior drain line was 2 inch and plugged frequently. This one has a lot of pressure and does not plug.
