10 Signs of Faulty Submersible Pumps

Shallow well jet pumps create air pressure using suction technology to draw water from a depth of 25 feet. A jet mechanism is installed at the bottom of the hole for deep-well jet pumps. The water is circulated by the jet as it is forced through a two-pipe system. This type of pump is used to extract water from depths of more than 25 feet.

Instead of employing suction, a submersible well pump mechanism forces the water upward. These small pumps, which are installed in the water well, are more dependable and effective than their antecedents, the previous jet pumps.

Faulty Submersible Pump Signs

The Broken Seal 

Lack of pressure frequently indicates that the pump needs to be filled with water. Low pressure can be brought on by a ruptured mechanical seal, a leaking pressure tank, or a pipe. Pressurize the pump and fill it with soapy water to look for leaks; the soap bubbles will help you find them right away.

The Low Pressure

The pump’s pressure switch controls the pressure, which is expressed in PSI (pounds per square inch). This device activates when the pressure drops below the minimum limit that has been specified. The pump is shut off if the pressure rises above the maximum level, though. The preset range is often between 20 and 40 PSI, 30 and 50 PSI, and 40 and 60 PSI.

The pressure switch should undergo routine inspection. Sand or dust particles can quickly jam the switch’s sensor, thus it should be clean and clear of obstructions. Before checking the switch, don’t forget to turn off the electricity.

Pipes filled with air

The pump is responsible if water is gushing out of the faucet with a “spitting” noise. Perhaps the pump is situated higher than the water level in the well. As a result, it pumps water ineffectively while also taking up a lot of air. Perhaps there is a leak in the pipes allowing the water and air to combine. To have the plumbing system inspected, think about hiring a plumber.


Check the oil dipstick if the coolant level drops below the authorized level but there are no leakage indicators. If it appears foamy, there can be a water pump leak.

Continuous Running Pump 

The water pump’s operation is controlled by the pressure switch. Without this mechanism, the pump would operate continually, which would stress your energy costs and increase the motor’s rapid burn and deterioration as well as the plumbing system. Additionally, a continuously running pump would cause the plumbing system to burst since it would overfill the pressure tank.

As a result, some submersible well pumps incorporate alarm systems that deliver notifications if the pump runs too frequently. Alternately, keep an eye on the pump’s operation frequently.

Lack of appropriate water pressure

 When you turn on your faucets, do they drip water? The culprit is the water pump. Low tank pressure or an inadequately sized pump may cause the plumbing system’s water flow to stall. Therefore, it is crucial to examine water usage. You need a medium-sized pump to maintain optimum pressure flow if your water demand is high.

Strange Noise

Having strange plumbing system noises? It might be broken mechanical machinery. There shouldn’t be any rattling, grinding, or shredding noises coming from a decent pump.

As an illustration, a rock lodged in the impeller can make a loud noise. The next obvious indicator of defective equipment is cavitation, which happens when tiny water bubbles collide with the impeller and leave a void. A rattling sound is made when a pump is placed incorrectly.

Water Contamination

The water becomes contaminated by dust, oil, rust, or soil, which gives it an odd tint and upsets the water supply, especially if it’s drinking water.

Submersible well pumps shield the water source from impurities and soil when they are installed beneath non-porous bedrock. Older jet pump versions, however, are more prone to infiltration. Therefore, have the plumbing system well-checked for foul odors.


If you notice steam coming from where the water pump was,  immediately dial the professionals. The friction frequently heats the pump, turning the water into steam. Equipment cannot be fault-checked without being opened.

No Water 

Switched on the faucet, and no traces of water. It’s time to check if the water pump is operating normally. Perhaps, the power source is dead or inadequate and hence cannot power up the water pump. Perhaps, a blown fuse or faulty wiring caused the pump to trip. Hire an electrician to examine the water pump and its electrical parts like wiring, fuse box, and control panel.
