Well Water Low Pressure Troubleshooting
If the water pressure from your well suddenly drops in pressure, several factors could be contributing to the problem. Leaky seals, loose fittings, misaligned valves, and other mechanical defects are common culprits. Getting a professional diagnosis is crucial to identifying the exact failure and choosing the best repair method.
What Happens When Well Water Loses Pressure?
From sputtering faucets to a weak shower spray, the symptoms of low well pressure tend to make themselves known right away. Here are the most common red flags:
- Sputtering or spitting faucets
- Weak showerhead spray
- Longer toilet tank refills
- Fluctuating or surging water
- Air bubbles in pipes
- Pump running constantly
- Discolored or murky water
- Slow filling washing machine
How Does Low Well Water Pressure Affect Appliances?
In addition to being incredibly frustrating, low well water pressure can have a direct impact on the lifespan of your appliances. Your washing machine and dishwasher both have design specifications that make them fill with water within a certain amount of time. When they exceed this time limit because of low water pressure, it puts immense strain on their motors and other components. Inlet valves may flutter or fail to close all the way, resulting in slow leaks that damage the appliances’ intake systems. Pumps may start to overheat or seize as they try to compensate for the lack of flow.
Undersized Pump
The pump is responsible for pushing/pulling water from the well. If it’s not properly sized for your plumbing needs, it will struggle to maintain steady water pressure.
Warning signs:
- Pressure drops when using multiple fixtures
- Slow pressure recovery after using water
- Pressure steadily declines over time
Solution: We’ll send a skilled plumber to perform a demand load test. This tells us whether the pump is the correct size. If it’s not, we’ll go over upgrade options that match your home’s water usage needs.
Problems With the Pressure Switch
The pressure switch is in charge of telling the pump when to turn on and when to turn off. It may fail to do its job correctly if it becomes dirty, corroded, or miscalibrated.
Warning signs:
- Pressure fluctuates wildly
- Pump turns on and off really fast
- Water takes longer to start flowing
Solution: We’ll clean and recalibrate the pressure switch. If it’s worn out or electrically faulty, we’ll replace it with a new one.
Failing Pressure Tank
Your well system has a pressure tank that stores water. It also stabilizes the pressure of the water between pump cycles. When the tank isn’t the correct size, the system can’t maintain a steady flow. A waterlogged tank can result in similar pressure fluctuations. Pressure tanks become waterlogged by developing leaks in the internal bladder or losing their air charge over time.
Warning signs:
- Pressure suddenly rises and drops
- Pump frequently cycles on and off
- Water flow comes out in bursts
Solution: We send the tank’s air bladder through a test to check its pressure and air charge. We may have to recharge the air bladder or replace the tank to prevent the short-cycling issue.
Declining Well Yield or Seasonal Groundwater Changes
Your system having low pressure may not have anything to do with the equipment. During dry seasons, the water table may drop below the pump’s intake level.
Warning signs:
- Pressure fades the longer you use it
- Issues become more noticeable during summer
- Pressure improves after the system sits unused
Solution: We’ll assess the well depth and water table to determine whether to lower the pump’s depth. If necessary, we can install a storage buffer system that stores water when demand is low.
Clogged Filters
Your system likely has anywhere from one to three filters on it. When these filters clog with sediment, silt, and other debris, the water pressure drops because the flow becomes restricted.
Warning signs:
- Gradually weakening pressure
- Reduced water flow at fixtures
- Appliances taking longer to fill
- Pump running longer than normal
Solution: We’ll check each filter to see which ones need replacement. Most filters last about three to six months before they start restricting water flow. If your well water has high amounts of sediment, sand, or silt, you may need to do more frequent filter replacements.
Mineral Scale Buildup in Pipes
Filters aren’t the only components that can clog on a well water system. It’s not uncommon for pipes to develop blockages from silt, rust, and sand. Homes with hard water tend to experience more frequent pressure drops because of the stubborn mineral scaling inside the pipes.
Warning signs:
- Pressure slowly weakens over time
- Some fixtures have stronger pressure than others
- Rust-colored or discolored water stains
Solution: We’ll descale the pipes using specialized cleaning solutions or pipe-flushing equipment. In homes with hard water, installing a water softener can help with scale buildup by dissolving minerals before they accumulate.
Partially Shut Water Valves
Your system has multiple valves connected to it, including a main shutoff valve, bypass valve, and isolation valve. If any of these are partially closed when they should be fully open, it can mess with the water pressure.
Warning signs:
- Pressure changes right after recent service
- Low pressure only in certain parts of the home
Solution: We’ll check every valve to make sure they’re correctly seated to deliver maximum water delivery.
