Best Sump Pump that you can buy. Nothing can stop it from working. One small problem is that the metal air hole in the pump will inevitably get clogged with gunk or rust so you need to drill a small 3/8th inch weep hole in the outlet pipe about 8" above the base of the pump and before the One Way Check Valve. This weep hole will allow any trapped air to escape and allow the pump to self-prime. If you get a large enough air bubble, the pump will run continuously and burn itself out while failing to pump out any water. Weep holes are needed for all sump pumps, no matter what brand.
