Review on 💪 Zoeller M53 Mighty-Mate Submersible Sump Pump - 1/3 HP - Enhanced SEO by Randy Salgado

The best sump pump money can buy. Nothing can stop him from work. One minor issue is that the metal air hole in the pump will inevitably become clogged with dirt or rust, so you'll need to drill a small 3/8" drain hole in the exhaust pipe about 8" above the base of the pump before using one Path. Check valve. This vent allows trapped air to escape and allows the pump to prime itself. If you get a large enough air bubble, the pump will run continuously and burn out without pumping water. Vents are required for all drain pumps regardless of brand.
