Water Pumps: How They Work, What the Failure Signs Are, and How to Prevent This

Mar 29, 2019

When you set up your well, you probably expect it to give you years of trouble-free use. However, parts, such as the well pump, can and do wear down and break. When you have problems once you turn on the tap, then that could be a sign that your well pump is about to break. Here is more about the way your well works, signs that your pump is failing, and tips on preventing well pump failure.

How Your Pump Works

If your well pump setup is typical, then the well pump is likely submerged deep in your well with pipes that run up to a pressure tank and then into your home. The pressure tank is on top of the well and helps maintain a consistent water supply when needed. The pump only runs when the sensor sends a signal that the pressure is low. Another type of pump is the jet pump which is also at the top of the well and draws water up through a pipe. Like the submerged pump, a jet pump works with a pressure tank and otherwise runs in a similar way as a submerged tank.

How Your Pump Shows Signs of Failure

The most obvious sign that your pump is about to fail is that nothing comes out when you turn on the tap. Another sign is when the water comes out after a period of sputters and hisses. Dirty or strange-smelling water is another sign of an imminent pump failure. You may also notice higher electrical bills because failing pumps tend to run constantly rather than only when the pressure is low. However, many of these signs could signify that other well components have failed. A leak in the pressure tank can cause your pump to run more often. Also, sand or dirt in the water may indicate a problem with your water table or the location of your pump. The best way to determine that your pump is the problem is to have a professional remove and examine it.

How to Prevent Pump Failure

Do these things to help keep your pump in good shape and ward off problems before they cause damage. Service Your Well Regularly You should already have a regular maintenance schedule for your well pump and check it at least once a year. Some pumps have a lubrication schedule and require regular bearing and seal replacement. Do a Visual Inspection Frequently Check your pipes, lines, pressure tank, and jet pump frequently. Take note of any water pooling or potential problems with tree roots. You should also check your exterior well components each time you do yard work or maintenance in the area. Make sure your pressure switch is clear of debris. Install a Low Water Cutoff A low-water cutoff switch ensures that your pump will shut off during times of high usage or water fluctuations. Shutting off the pump in low-water situations helps keep it from overheating and burning out prematurely. Install a Sediment Filter A sediment filter may help protect your pressure tank so that it is less likely to burst or have problems. Generally, the filter goes between the pump and your pressure tank, though some configurations may differ. Reducing problems with the pressure tank means less chance that your pump will cycle unnecessarily. If you have an old system, and your pump shows signs of imminent failure, then you may need to replace it. However, if your pump is new, then you have a chance of repairing. If you think that your well pump is failing, or you aren't sure of the cause of the problem, then contact Brown & Cox and have us come and check it out.
