Part 800-305 is a replacement foot valve housing used in the fluid intake system of compatible airless sprayers. This housing contains the foot valve assembly and connects the suction hose to the pump, controlling material flow into the pumping chamber. When the original housing becomes cracked, worn, or corroded, replacement restores proper fluid flow and prevents air ingestion.

The 800-305 foot valve housing is a direct replacement component for the fluid intake system on a wide range of airless sprayers including 840 i, 840 IX, 840 ix Airless Sprayer, 840i Airless Sprayer, 1140 i, 1140 ix Airless Sprayer, 1140 IX, Iimpact 840 I and IA, impact 740, Impact 740-840, Impact 840 service, impact 1040, impact 1140 I and IA, Impact 1140 service, and Performer 1140 ix. This housing mounts at the end of the suction hose and contains the foot valve assembly, which includes a check ball and seat. The foot valve allows material to enter the hose on the intake stroke and prevents backflow during pressure cycles, maintaining pump prime. A cracked, worn, or corroded housing can cause air ingestion, loss of prime, and external leaks. This replacement housing is manufactured from corrosion-resistant materials to match original specifications for thread fit and sealing surfaces. Installation requires proper sealing of connections and installation of a new foot valve assembly. Regular inspection helps identify housing damage before it leads to operational issues.
