The SPP2-4A uses a separate low-level floor sensor instead, allowing the switching point to be located independently from the pump and enabling automatic operation at much shallower water depths.\u003c\/p\u003e\n\u003cp\u003eExplore our wider ranges of \u003ca href=\"https:\/\/floodandwaterpumps.co.uk\/collections\/stream-pumps\"\u003eStream pumps\u003c\/a\u003e, \u003ca href=\"https:\/\/floodandwaterpumps.co.uk\/collections\/puddle-pumps\"\u003epuddle pumps\u003c\/a\u003e and \u003ca href=\"https:\/\/floodandwaterpumps.co.uk\/collections\/submersible-pumps\"\u003esubmersible water pumps\u003c\/a\u003e.\u003c\/p\u003e","brand":"Stream Pumps","offers":[{"title":"Default Title","offer_id":56378162839931,"sku":"SPP2-4A","price":124.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0845\/0857\/4015\/files\/SPP2-4A_Automatic_Puddle_Pump.jpg?v=1786703514","url":"https:\/\/floodandwaterpumps.co.uk\/products\/stream-spp2-4a-automatic-puddle-pump","provider":"Flood \u0026 Water Pumps","version":"1.0","type":"link"}
