Solo Replacement Diaphragm Pump to Suit 475 Backpack Sprayer

To fit this replacement diaphragm pump, first depressurise and empty your Solo 475 backpack sprayer and disconnect it from any chemical supply. Remove the worn pump assembly following your sprayer's operating manual, fit the new diaphragm pump ensuring all seals are seated correctly and connections are secure, then test with clean water before returning the unit to service. Tips: Flush the sprayer with clean water and confirm no chemical residue remains before working on the pump, and wear gloves and eye protection while handling parts that have contacted chemical. Check the diaphragm and seals are seated correctly to avoid leaks. Keep the old parts until you have confirmed the replacement is working.
