Review on KEDSUM 330GPH Ultra Quiet Submersible Pump With High Lift And Grounded Power Cord - Ideal For Fish Tanks, Ponds, Aquariums, Statuary, Hydroponics - Includes 3 Nozzles And 1500L/H Water Flow by Devin Bro

First pump purchase was initially great. Plenty of lift, just as advertised. Connected it to a timer system for my hydroponic and off we went. About 60 days in, it started having issues with generating the lift. Did all the usual stuff of cleaning it and such. No apparent reason as to why it was failing. It was intermittent and we were hoping it would go away. By 90 days, it just stopped being able to generate any lift. Thought we were just unlucky as the return period expired prior to that.So we bought a second one. And guess what, here we are about 45 days in for the second one and its starting to do the exact same thing.No warranty listed on the page, so it appears we just wasted our money.
