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 Deborah Nystrom

I bought this pump to replace the same pump in my birdbath. First worried that unlike the previous pump, it doesn't use a grounding plug. This isn't a problem as the outlet it plugs into is GFI protected. It's very quiet and does what it's supposed to. I read in another review that the adapters that came with it don't fit. The pump comes with an adapter already installed, which must be removed first to install other adapters.
