At the moment I use a cheap commercial Elemental Air Pump 1744 GPH. My last one crapped out at almost a year old, still under warranty they sent me a new one so back in business. If it wasn't for the fact we were remodeling the kitchen I would have bought a different quieter brand such as Alita or WON Brothers.
Last month I noticed the pump getting louder and louder, then I noticed the water output was very VERY low, once I plugged the new one in, the output was restored and water was flowing again.
