Air locking on a sump pump happens when there is air between the pump and the checkvalve of the discharge line. The trapped air prevents the impeller from drawing in enough fluid to open the checkvalve to allow discharge. The weight of the fluid on the topside of the checkvalve keeps it closed. The problem is often noticed after the initial use, when the pit has had time to dry out during a dry spell. When it gets water in the pit again, the air lock condition shows up. The pump runs due to the float switch being raised, but can't eject the water because of the air lock condition.
Quick fix!!! Drill a 1/8" hole on an upward angle into the pipe below the checkvalve, or within the pit if the checkvalve is too high above the pit. The water will push the excess air from the discharge line allowing the pump to start the water removal. You will get a steady stream of water from the drilled hole as a result, but the air lock problem should be a thing of the past. This info should be in owners manual that came with the pump.

What is the purpose of a sump pump vent and how does it contribute to the overall functionality of a sump pump system?
The purpose of a sump pump vent is to release air pressure from the sump pump system, allowing water to flow freely and preventing airlocks. This helps the sump pump operate efficiently by ensuring proper drainage and preventing clogs or malfunctions.
What are possible causes of the pulley on the air pump locking up?

How does evaporator sump pump work on a home air conditioner?
Centrifugal pump impeller discharges through outlet to manifold in top of unit where water is distibuted through media and what does not evaporate returns to sump. Water level in sump needs to be higher than pump base, as this is the inlet to pump.
What is Sump Pump Repair and why do I need it?
You would need a sump pump repair if the sump pump in your basement is not pumping out water. The purpose of a sump pump is to drain excess water that is part of your waterproofing system.
Does a sump pump need a hole in the pipe above the pump?
The hole in the pipe is to break an air lock that the pump may develop if the sump ever runs dry or the water level drops below the intake of the pump. Air inside the pump might not be purged out when the water level rises and the pump is called to turn on, causing the pump impeller to 'run dry' inside the pump. The hole allows the air to escape and the pump to prime itself and operate without an air lock condition.
Where does a sump pump drain water from?
A sump pump drains water from a sump pit or basin located in the lowest part of a basement or crawlspace.
What is the process for replacing a sump pump battery?
To replace a sump pump battery, first, disconnect the old battery and remove it from the sump pump. Then, install the new battery by connecting it to the pump following the manufacturer's instructions. Finally, test the sump pump to ensure the new battery is working properly.
What are the best options for a sump pump cover square to protect your sump pump system?
The best options for a sump pump cover square to protect your sump pump system include durable plastic covers, metal covers, and custom-fit covers. These covers help prevent debris from entering the sump pump system and ensure proper functioning.
What is the purpose of a sump pump bucket and how does it contribute to the functionality of a sump pump system?
The purpose of a sump pump bucket is to collect water that enters the sump pump system. It helps prevent flooding by holding the water until the pump can remove it. The bucket also helps keep the pump from running too frequently, which can extend its lifespan.
What are the necessary steps for installing a sump pump in a crawl space?
To install a sump pump in a crawl space, follow these steps: Determine the best location for the sump pump pit. Dig a hole for the pit and place it in the ground. Install the sump pump in the pit and connect it to a power source. Install a check valve on the discharge pipe to prevent backflow. Test the sump pump to ensure it is working properly. Install a sump pump cover to prevent debris from entering the pit. Regularly maintain and check the sump pump to ensure it continues to work effectively.
Will a 2000 watt inverter power a sump pump?
It depends on the power requirements of the sump pump. For a typical residential sump pump, a 2000 watt inverter should be enough. However, it's important to check the power consumption of your specific sump pump to ensure the inverter can handle it.
