How to Properly Prime a Shallow Well Pump and Overcome Common Challenges 👨🔧
Introduction
Are you struggling with priming your well pump? Whether you have a shallow well pump or a Sandpoint pump, this article is here to help. Priming a pump may seem like a simple task, but it can be more complex than it appears. In this guide, we will walk you through the process of priming a pump and address the common challenges that may arise. By the end of this article, you will have a better understanding of how your shallow well pump system works and how to overcome any difficulties you encounter.
Understanding the Pumping System
Before diving into the priming process, let's take a moment to understand how a shallow well pump system works. A shallow well pump is designed to draw water from a sandpoint well, which consists of a pipe driven into the sand. In most cases, the depth of the well ranges from 17 to 18 feet. The pump's intake is connected to the well pipe, and the output is connected to a pressure tank, which distributes the water to various areas of your property. It's crucial to ensure that your well has an adequate water supply before attempting to prime the pump.
Checking for Water in the Well
The first step in priming your pump is to verify if you have water in your well. You can easily determine this by using a string with a heavy knot attached. Lower the string into the well and listen carefully for the sound of water. If you hear the water, it's an indication that your well has a sufficient supply. Additionally, by measuring the length of the string, you can estimate the depth of the water in the well. Ideally, you want the water level to be several feet higher than the sandpoint to ensure proper water flow.
Ensuring Proper Flow
Once you have confirmed the presence of water in your well, the next crucial step is to check for flow. Flow refers to the ability of water to move from the surrounding substrate into the well pipe and up to the pump. To assess the flow, connect a garden hose to a water source and place it into the well pipe. Turn the water on at full force to simulate a significant flow. Observe how quickly the water comes up through the pipe and how long it takes to drain back down. If the flow seems slow or the water takes a considerable amount of time to drain, it may indicate a clogged sandpoint. In such cases, you can use vinegar or acid tablets to remove mineral deposits and improve the flow.
Evaluating the Check Valve
One crucial component that affects the priming process is the check valve. The check valve ensures that water can flow in one direction and prevents backflow. A foot valve is an alternative to a check valve, typically used in situations with a separate pipe at the bottom of the well. To check if your check valve is functioning correctly, you can perform a simple test. Fill the pipe with water or top it up to a certain level and leave it for a few hours. If the water level remains the same, it indicates that the check valve is holding water effectively. However, if the water level drops significantly, it suggests a faulty check valve that may require replacement.
Detecting Leaks on the Vacuum Side
Another factor that can hinder the priming process is the presence of leaks on the vacuum side of the system. The vacuum side refers to the suction side of the pump, which is prone to air leaks. Any leaks on this side can disrupt the vacuum and prevent the pump from achieving proper priming. To check for leaks, you can either pressurize the system with air or water and observe for any signs of leakage. Additionally, when your pump is running, listen closely for any hissing or sucking sounds that may indicate a vacuum leak. Detecting and resolving these leaks are essential to ensure a successful priming process.
The Science Behind Pump Priming
To fully understand the priming process, it's important to grasp the science behind it. Shallow well pumps, while highly efficient at moving water, struggle to move air effectively. This is why priming involves filling the pump chamber with water before starting the pump. By doing so, you create a vacuum that allows the pump to draw water up from the well. However, due to the presence of air in the suction side pipe, multiple priming cycles may be required to achieve optimal results. It's crucial to note that shallow well pumps have limitations, and they can only create a vacuum sufficient to draw water from a maximum depth of 25 feet.
Steps to Prime the Pump
Now that we have covered the basics, let's dive into the step-by-step process of priming your shallow well pump. Before starting, ensure that you have all the necessary tools and materials, including Teflon tape, a gauge, and a plug. Here's what you need to do:
- Close the faucet or valve located outside to minimize backpressure.
- Fill the pump chamber with water, ensuring it reaches the top.
- Install the gauge on the designated fitting.
- Start the pump and monitor the pressure as it rises.
- Allow the pump to reach the cut-off pressure but avoid surpassing it.
- Shut off the faucet and wait for the pressure to drop.
- Unplug the pump, releasing any pressurized air.
- Seal the chamber with your thumb and plug the pump back in.
- Repeat the process until the water comes all the way up and stays in the chamber.
By following these steps and being patient throughout the process, you can effectively prime your pump and ensure a steady water supply.
Troubleshooting Common Issues
Despite following the priming procedure, there may still be instances where challenges arise. One common issue is the loss of prime, where the pump requires frequent re-priming. If you find yourself in this situation, it usually indicates a faulty check valve or foot valve. Check these components to ensure they are functioning correctly and holding water as intended. Additionally, be cautious of any leaks on the pressurized side of the system, as they can introduce air and disrupt the priming process.
Alternative Priming Methods
While the traditional priming method we discussed earlier is the most common, there are alternative methods you can explore. One particular method involves using a pitcher pump or a self-priming pump. A pitcher pump can be attached to the fitting on the pump and manually operated to create a vacuum that draws water in. Similarly, a self-priming pump, powered by a drill, can be used to expedite the priming process. These alternative methods can be helpful in situations where constant re-priming or a faster priming process is desired.
Conclusion
Priming a shallow well pump may come with its challenges, but with the right knowledge and approach, it can be achieved successfully. By understanding the components of the pumping system, checking for water flow and leaks, and following the proper priming steps, you can ensure a smooth and efficient priming process. Remember to address any issues promptly and explore alternative priming methods if needed. With these insights, you can confidently overcome any obstacles and enjoy a reliable water supply from your shallow well pump system.
