This creates an immediate vortex that ensures a perfect, uniform mix and prevents heavy concentrates from settling unmixed at the base of the tank. \n  \u003cbr\u003e\u003cbr\u003e\n  After finishing your application, vent the air pressure using the safety relief valve, empty any leftover chemical responsibly, and pump 1 to 2 litres of clean water through the lance. This simple flush prevents chemical residues from drying out and clogging the internal nozzle seat, keeping your Solo sprayer flawless for years!\n\u003c\/blockquote\u003e","brand":"Heiniger","offers":[{"title":"Default Title","offer_id":47935446057060,"sku":null,"price":69.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/6487\/0244\/files\/Gemini_Generated_Image_eit961eit961eit9.png?v=1771674271","url":"https:\/\/www.greenhousepolytunnels.com.au\/products\/solo-409-professional-garden-pressure-sprayer-7l","provider":"Greenhouse \u0026 Polytunnels","version":"1.0","type":"link"}
