Fixing a Water Well That Has a Declining Yield
When your well starts producing less water than it used to, you might notice it first at the kitchen sink, where the flow slows to a trickle, or in the shower, where the pressure feels weaker. For folks who depend on a well for their water, a declining yield can be a real hassle, making tasks like laundry, cooking, or watering the yard more difficult. A well that’s losing output isn’t just inconvenient—it can signal underlying issues that need attention to avoid bigger problems. The good news is that many causes of declining yield are fixable, and with the right approach, you can restore your well’s performance. In this article, we’ll explore why your well’s yield might be dropping, walk you through practical steps to fix it, and show how the Well Harvester can keep your water flowing strong, especially for low-yield wells.
What Causes Declining Yield
A well’s yield—how much water it can produce per minute—can decline for a variety of reasons, from mechanical failures to natural limitations. You might notice weaker pressure at the tap, slower flow to appliances, or difficulty keeping up with household demand during busy times. The issue could stem from a struggling pump, a clogged well, or a dropping water table that limits available groundwater. Environmental factors, like drought or nearby development, can also reduce output. Understanding the cause is the first step to fixing the problem. By examining the well system and its surroundings, you can identify what’s holding back the yield and take targeted action to boost production.
Checking the Well Pump
The well pump is the heart of your system, pulling water from the aquifer and delivering it to your home. If it’s not working properly, your well’s yield can suffer. Submersible pumps, used in most modern wells, sit deep underground and rely on a steady power supply and regular maintenance to perform. A pump might struggle if its internal parts, like impellers or bearings, are worn out, or if it’s not sized correctly for the well’s depth or demand. Check if the pump is getting power and listen for odd noises, like grinding or humming, which could signal wear or damage. If the pump feels hot, it might be overworking due to low water levels, a common issue in low-yield wells. A well technician can test the pump’s performance and suggest repairs or a replacement if needed. The Well Harvester helps protect pumps by preventing over-pumping, stopping the pump before the well runs dry, which is especially crucial for maintaining yield in low-producing wells.
Inspecting the Pressure Tank
The pressure tank plays a key role in delivering consistent water flow, storing water and maintaining steady pressure throughout your home. If the tank is faulty, it can make the well’s yield seem lower than it actually is. A waterlogged tank or a damaged bladder can’t hold enough water, leading to weak pressure or flow that fluctuates. You might notice the pump cycling on and off more often, a sign the tank isn’t working right. Inspect the tank for rust, leaks, or signs of waterlogging, like pressure that varies at the tap. A technician can test the tank’s pressure and fix issues by repressurizing it or replacing the bladder. Tanks typically last 5 to 15 years, so an older one might need replacing.
Assessing the Well’s Condition
Sometimes, the well itself is the source of declining yield. Sediment, minerals, or bacteria can build up on the well screen or casing, a problem known as biofouling or incrustation, especially in older wells or areas with hard water. This can restrict water flow, causing cloudy or gritty water and a steady drop in output. A well technician can use a camera to inspect the well’s interior, checking for buildup or damage. Cleaning the well with chemical treatments or high-pressure jetting can restore yield, but it’s not a permanent fix if the conditions causing the buildup persist. The Well Harvester helps prevent these issues by slowing and spreading out water pumping, reducing sediment disturbance and mineral buildup. Its controlled pumping keeps the well clear and productive, supporting higher yield over time.
Evaluating the Water Table
A dropping water table is a common cause of declining yield, particularly for low-yield wells that already produce limited water. The water table—the level of groundwater in the aquifer—can fall due to drought, seasonal changes, or heavy water use from nearby wells. If the water table drops below the pump’s intake, the well can’t produce enough water, leading to lower yield. You might notice this as a gradual decline in flow or pressure over weeks or months. A professional can measure the water table’s depth and assess the aquifer’s health. Solutions like lowering the pump or drilling a deeper well can help, but they’re costly and don’t guarantee a solution to the problem. The Well Harvester is designed to address this challenge, adjusting water draw based on real-time water levels to maximize output without overtaxing the aquifer. Its ability to adapt to changing water tables makes it a smart choice for wells with declining yield.
Checking Plumbing for Issues
Declining yield might not always be the well’s fault—plumbing issues can also reduce flow. Leaks, especially underground, can waste water and lower pressure, making it seem like the well is underperforming. Clogged pipes, caused by mineral buildup or sediment, can restrict water movement, further limiting flow. Look for wet spots in your yard, dripping faucets, or higher-than-normal water use to spot potential leaks. Inside the house, inspect pipes for corrosion or scaling that might narrow the flow path. A plumber can clear clogs or fix leaks to improve flow, often making a significant difference.
Addressing Environmental Factors
Environmental changes can also contribute to declining yield. Prolonged droughts can lower the water table, reducing available groundwater, while heavy rains might stir up sediment, clogging the well and limiting output. Nearby construction, like new wells or roads, can disrupt the aquifer, causing unexpected drops in yield. If you notice cloudy water or a sudden dip in flow, these could be signs of environmental impacts. A professional can test the well and assess external factors affecting performance. The Well Harvester adapts to these challenges by optimizing water draw, ensuring a reliable yield even when environmental conditions shift. Its controlled pumping reduces strain on the aquifer, helping maintain production in tough situations.
Exploring Solutions for Low-Yield Wells
For wells with chronically low yield, advanced systems offer the best long-term fix. The Well Harvester is a standout solution, especially for low-yield wells struggling to meet demand. Its patented technology monitors water levels and adjusts pumping to maximize output while preventing over-pumping, protecting both the pump and the aquifer.

The 215-gallon, food-grade, FDA-approved storage tank holds plenty of water for peak demand, so you’re covered during busy times. With regular optimizations to adapt to changing water tables, the Well Harvester keeps your well productive year-round. Backed by a three-year warranty and financing options from Epp Well Solutions, it’s an affordable way to fix declining yield and ensure a reliable water supply.
Taking Action to Restore Yield
To fix a well with declining yield, start by checking the pump for wear or improper sizing, and have a technician test it if needed. Inspect the pressure tank for waterlogging or damage, as a faulty tank can mimic low yield. Examine the well for blockages with a camera inspection, and clean it if buildup is present. Assess the water table with a professional to see if a dropping level is the issue, and check plumbing for leaks or clogs that might be reducing flow. Address environmental factors like drought or construction that could be affecting the aquifer. For low-yield wells, consider the Well Harvester as a long-term solution to boost production. A well technician can guide you through the process and recommend the best fixes for your well.
