Review on Simple Deluxe LGPUMP80G 80 GPH Submersible Water Pump: Ideal for Fountains, Ponds, Aquariums and Hydroponics, with 6' Cord and 2 Threaded Nozzles - Versatile and Efficient - Black, 1-Pack by Brittney Singh

Bought to replace the pump in a water bowl at home. First I noticed a strange oil over the block. It won't come off your hands or the pump itself without multiple washes. I took the pump apart and soaked it in white vinegar and water to clean it before use, but found the oil to be stable. Even a wash attempt with Dawn brought no results. It turned on and worked fine, but I wouldn't trust them with anything meant for a pet. Will return.
