So you built a new well and wonder how long you can run a well pump without damaging it? You are at the right place.
In this short guide, we will discuss all the things you need to know about how long a well water pump should run, what could be dangerous if the pump runs for too long, or what happens to your pump when the water level falls below its impeller.
How Long Should A Well Water Pump Run?
A well pump will run until it fills the water tank in your home. The water tank is connected with well pump and signals the pump to turn on/off depending on the water level in the tank.
Having said this, it is important to know how long the well pump should run continuously to avoid any danger. It depends on pump type. Some pumps are designed for longer operations, while most have a maximum continuous running time of 2 hours before they need to cool off. Some latest models stop running after a fixed time to avoid overheating. Most private well systems for homes have this type of pump.
Moreover, well pumps are water cooled. They need water to stay cool and function properly. If the water level in your well falls below the pump’s propeller, there is a high chance that it can go bad.
Your pump’s operator manual mentions working times, maintenance needs, and pump capacity.
Hence, the exact time your well pump will run depends on your tank’s size, drawdown from the tank, pressure setting on the pump, and volume of water in your well.
What to do if my pump runs too much?
If you see that your pump runs too much or turns on/off frequently, you need to check your well water tank and pump’s pressure setting. Analyze why the water level is fluctuating in the tank. The setting on your well pump could have been disturbed. You need to adjust the settings. The well pump may have lost the prime, or the pressure control switch is faulty.
There can be a running appliance in your home that’s continuously drawing water. The well piping can leak, forcing the pump to go on/off often.
How often should a well pump cycle?
It depends on water usage, tank size, and motor power. You can’t control pump cycles because you can’t control the water usgae, especially if you have kids at home. Well experts recommend minimum pump cycles to increase its lifespan and functionality.
The well pump cycle time is between 30 seconds to 2 minutes if everything in your well water system works optimally.
Why is my pump cycling on and off frequently?
It is known as short-cycling and happens when you use too much water at once, more than what your pump can handle. For example, running all the taps at your home or using all the appliances at once. Sprinklers often cause this problem because it uses a lot of water at one time.
Why does the well pump burn when it runs for long?
When the water level falls below the pump’s propeller, it overheats. This results in extra heat generation and no cooling because there is no water inside the pump to cool it. The pump burns as a result.
