Does the water line to the Laminar need to be filtered?

YES! All CMP water features including laminars should ONLY use filtered water. The water line to the laminar must be filtered and installed with a check valve. Do not use a sand filter.

Operating with unfiltered water will degrade the water flow performance and could permanently affect the water feature. Water features damaged by unfiltered water are not warrantable.

We recommend the CMP Water Feature Filter or other cartridge filter.
