Review on 🚤 Efficient Ogrmar Automatic Boat Bilge Pump Float Switch – Moisture Tight Seals, Ignition Protected Mercury, 12/24/32VDC by Andre Tenk

Float lever stuck in up position. There was no debris or anything preventing it from falling when the water level dropped. As a result, he worked for several hours with the float raised, but without pumping water. It was used as a switch replacement in the marine shower drain box, so there is only clean water there. If it was in the hold of a boat, it would likely result in thousands of dollars in fines for dumping spilled oil on the bilge water. As if it "only" destroyed the pump.
