What Causes Water Pumps to Fail? Protect Your Pumps with These Tips

The larger your New York City property is, the more pumps you use in its day-to-day operation — for water distribution, fire suppression, boiler operation, and more. Here is a review of what causes water pumps to fail, so you can better understand what’s happening if one of your pumps is malfunctioning. We’ve also included some tips about how to fix these issues, many of which you or your management crew can try on your own before calling Antler Pumps for a service visit.

Causes of Water Pump Failure

Improper mounting or installation

Nature of the problem

Pumps must be properly secured in place to prevent excess movement that can compromise their function. Depending on the type of pump, it must be bolted or strapped into place to keep it steady. Pumps must also be level or plumb (perfectly vertical according to the force of gravity) to run correctly.

Signs to watch out for

If you notice the entire pump is moving around or making excess noise during operation, the mounting may need tending to. Some pumps may fail to turn on automatically in this situation.

Prevention tips

Most pumps should be installed by a pump specialist, like Antler Pumps. We always make sure mountings are secure, which you can check, too. In the case of devices like sump pumps, we check to ascertain that they are not tipped off the vertical, which can cause failure.

Pump too small for demand

Nature of the problem

All pumps must be the right size for the job they are to perform. When a pump is the wrong size, typically, it’s too small for the demand placed on it.

Signs to watch out for

There are multiple signs that a pump isn’t up to the task at hand, such as:

  • Running constantly when it should only be operating intermittently
  • Inadequate water pressure
  • Failure to pass sprinkler inspection test
  • Frequent breakdowns necessitating repair or replacement parts
  • Downstream problems due to reduced volume of flow
  • Water damage or sewage backup (sump pumps or sewage ejector pumps)

Prevention tips

Again, professional installation of a pump can avoid this problem. You may think you’re saving money, but in the end, it’s costing you more to buy a smaller pump for less. When you upgrade building systems or add onto your property, always consult with your pump experts to ensure your existing pumps can handle any load changes.

Reaching the end of its lifespan

Nature of the problem

Sometimes, pumps simply become too old to operate properly anymore.

Signs to watch out for

You will notice virtually all of the warning signs listed in this post when a pump nears the end of its useful life. Most importantly, it can no longer be tuned up or repaired. Sometimes parts are not available for it.

Prevention tips

Keep track of the age of your pumps and know their predicted life expectancy. Perform routine maintenance as suggested by your pump professionals. Don’t wait until little problems become bigger ones, as this can reduce any pump’s lifespan.

Inadequate water filtration

Nature of the problem

Pumps in New York City rental properties typically move thousands of gallons of water every day. If the quality of the water is not good, it can cause problems with the pump.

Signs to watch out for

Most of New York City’s water is fortunately not too hard, save for a few areas in Queens. However, sediment, rust, and other undesirable materials can still accumulate in your pumps. You’ll see this everywhere; the pump itself may become clogged, and you may notice sediment or discoloration in tap water, the boiler tank, radiators, appliances, and the like.

Prevention tips

A thorough filtration system can catch sediment and particulates further upstream from your pumps. Together with our partners at Sanitary Plumbing, we can suggest the right water filtration system for your building, whether that’s a simple strainer-type filter or something more sophisticated to treat additional issues simultaneously.

Disintegrating seals or gaskets

Nature of the problem

Seals, gaskets, and O-rings are used in pumps to prevent leaks throughout the entire pump mechanism, including on the interior of the pump. These are subject to wear and tear that make the pump less effective overall.

Signs to watch out for

As well as pump malfunction, the biggest sign of a worn, cracked, or torn gasket is leaking water. This may be a small drip or a more substantial flow.

Prevention tips

In-house pump inspections should always include checking over all seals. Call your pump specialists as soon as you notice any leaks, so new components can replace those that are no longer working properly.

Bearing or lubrication problem

Nature of the problem

Just like the pumps in your motor vehicle, water pumps use bearings and/or lubrication to prevent friction and run more smoothly. When you have excess friction, the pump may not run efficiently or may fail completely.

Signs to watch out for

Your pump may not run as it used to when bearings or lubrication need maintenance. Two telltale signs are:

  • The pump runs very hot as a result of friction and may even shut down due to overheating.
  • The pump is noisy when operating, making grinding or shrieking noises.

Prevention tips

Call your pump experts if you observe either of the two signs above. Regular pump maintenance usually catches this problem before the pump becomes damaged or fails.

Sensors not working properly

Nature of the problem

Many pumps today utilize sensors that trigger the pump to operate automatically. When the sensor malfunctions, the pump fails to turn on or off.

Signs to watch out for

Usually, when a sensor is at fault, a pump simply won’t turn on when it should. Your boiler level could get low if this happens with the automatic water feeder. When a sump pump sensor fails, you will have rising water coming up into the property. Sewage or wastewater can back up when a sewage ejector pump basin overfills due to sensor failure.

Prevention tips

Some sensors are more complex than others and may require professional attention. However, you can try this fix on your own: make sure the sensor isn’t stuck to the side of whatever vessel it sits in, whether that’s your boiler tank, sump pump basin, or sewage ejector pump basin. Sometimes that entails giving the basin a good cleaning and removing any obstacles. It may also be that the sensor or the arm that holds it needs replacing. As much as possible, we recommend pump controls to alert property owners and managers to sensor problems before they morph into serious scenarios.

Cavitation

Nature of the problem

Cavitation is a potentially dangerous situation where cavities or bubbles in high-pressure water, such as in a commercial boiler system, collapse. The resultant shock waves can cause permanent damage to the pump’s impeller, cause the pump to fail entirely, and even cause safety issues due to unsafe pressure.

Signs to watch out for

Boilers and other systems in which cavitation is occurring are noisy. It can sound like there’s gravel rolling around the pump, and you may see cauldron-like bubbling in the water. The pump may provide insufficient flow, vibrate, or shut off (especially if you use a control system that catches cavitation). Pitting in the metal of a pump’s impeller or corrosion is a sign of past cavitation.

Prevention tips

Depending on the type of pump involved, there are various solutions to cavitation, most of which must be implemented by a pump specialist:

  • Make sure the pump isn’t operating faster than it needs to be (slowing it down can reduce pressure).
  • Monitor the temperature of the water being pumped to ensure it’s not too high.
  • Consider using a booster pump to reduce the load on your primary pump.
  • Make certain the pump’s impeller is the right size and configuration for its task.
  • Check to be sure liquid levels are adequate at the pump’s suction side.
  • Never use a pump that’s too small for the load it has to handle.
  • Try increasing the space between the pump impeller’s vanes and the casing/shrouding (the general rule of thumb is at least four percent of the impeller’s diameter).
  • Make sure the pump and its valves have no blockages and that everything else is functioning correctly.
  • Use a pump controller to monitor the pump’s function automatically and prevent situations that lead to cavitation.

Electrical power malfunction

Nature of the problem

Most pumps these days are electrically powered. Therefore, any problems with the electrical components will affect the pump’s ability to move water.

Signs to watch out for

There are many ways electrical issues can manifest with your pump:

  • Failure to turn on
  • Pump running intermittently
  • Pump won’t shut off
  • Worn or frayed wires or other electrical elements (plugs, outlets, etc.)
  • Circuit breaker triggered or lights dim when a pump comes on
  • Shocks when touching pump components
  • Pump overheating

Prevention tips

Your pump specialist can check for electrical issues related to the pump during maintenance calls or service. Anything caused by the larger electrical system should be addressed by a licensed electrician immediately.
