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 Heidi Garcia

This little pump worked fine at first, but after a little over a month it became loud enough to drown out the sound of rushing water. I have cleaned and adjusted it many times and it has never worked the way it started out. Of course, the return window closed after a month. I didn't notice that he had such a short return period, otherwise I wouldn't have bought it at all. It usually takes more than a month for mechanical things to fail, so obviously this manufacturer knows it is an inferior product.
