Description
4FRCAP – 4″ Rubber Fernco Cap
This Flexible Rubber Cap is an Earth Pond waterfall accessory used in creating our custom Earth Pond Intake Fields, which filter and aerate large ponds and small lakes. They cover the end of 4″ slotted pipes in a connected intake field. This forces the water to be filtered through the pipe slots.
- Pond waterfalls not only beautify the landscape, they aerate the pond which helps manage algae growth.
- Water is drawn through a set of connected slotted pipes by an external pump, which pushes it to the waterfall box.
- Pipe Intake Field will require gravel to cover the entire system and piping, to keep the pipe system weighted to the bottom of the pond.
