Cleaning System

Pressure-Flo features a revolutionary patented Easy Clean Backwash-Cleaning System that completely cleans the entire surface of the foam filters, and has had significant improvements so is now even easier to use than before.

Pressure-Flo 4000 is designed to work in tandem with a solids handling pump, ideally a Laguna Max-Flo waterfall and filter pump. With the filter connected to the pump, water enters the unit through a water inlet. It then passes through the mechanical filtration stage, consisting of highly durable foam filters that intercept and trap dirt and debris.

Dirt-free water then passes along an integrated 13W UV-C lamp, where it is exposed to ultraviolet rays that inhibit the growth of algae. Water finally returns to the pond thoroughly cleansed. This patented system is the only one of its kind. Backwash cleaning can easily and comfortably be completed in a few minutes without opening the lid. This feature ensures that the filter performs at optimal levels for many days and prolongs the time between full maintenance sessions.

Cleaning Indicator

Pressure-Flo 4000 includes a cleaning indicator that lets you know when the filter needs a backwash or cleaning. The height of the red cleaning indicator is approximately proportional to the level of filter clogging. If the red indicator is low, the filter is clean. If the red indicator is fully exposed, the filter needs cleaning. The cleanliness indicator can be affected by various variables, such as the height of the water drop and the performance of the pump. Different conditions of use can lead to different results..
