This document is the FullFlow™ Valve user manual, including installation, operation and maintenance information.
The Pentair FullFlow Valve is a high-quality, corrosion-resistant component designed for pool filtration systems. It operates by reversing water flow from the filter to the backwash position when turned 90 degrees, introducing virtually no pressure drop to the system. The valve is available in two models: one for sand filters and one for diatomaceous earth (D.E.) filters, distinguished by their port connections and dimensions.
| Maximum Operating Pressure | 50 psi |

Pentair recommends using DOW CORNING 111 LUBRICANT, as other types may damage plastic or rubber components.
Pentair recommends inspecting the Waste Seal and small shaft seal after three months and reassembling for a check in three more months.
It indicates that the seals no longer have adequate lubrication and should be re-lubricated to prevent damage to O-ring seals.
