A building’s water pump operates quietly behind the scenes, pushing water from the primary source to the various units and common areas of the building. While you may take wonderful care of your building’s pump, things can still go wrong and cause it to break down sooner than you’d like. Not only can this cause disruptions, but it can also result in property damage and lead to costly emergency repairs.
By being proactive and taking care of your pumps, you can prevent major issues from arising. To help you identify potential problems, we’ve outlined the common signs that indicate your building’s pump needs immediate repairs.
Unusual Sounds
While you should expect to hear some noises coming from your pump, some noises should raise concerns. Go into your pump room and check for the following sounds.
- Grinding indicates worn bearings or metal-on-metal contact within the pump housing.
- Clanking suggests loose or misaligned components that create vibrations and mechanical stress throughout the system.
- Whining or Squealing points to motor bearing failure or impeller problems.
- Hissing indicates air in the system or a leak coming from the seal on the pump or other areas of the plumbing system.
If you notice any of these sounds coming from your pump, contact a qualified technician immediately so it does not compound into a larger issue.
Improper Water Pressure
If you turn on a faucet or other water fixture and notice that the water seems to trickle out, the pressure may be too low. Internal wear, such as worn seals or damaged housing, can cause a pump to lose its ability to maintain proper pressure. Sometimes, low water pressure also occurs because of a blockage in the line, which requires a professional to clear.
On the other hand, you may turn on a tap and have water rush out at full blast. This is an indicator of high water pressure, which can also cause damage to fixtures, appliances, and your pump system. Your pump’s pressure may be too high if there’s an issue with the pressure regulator, the valves are closed, or if the pump is too big for your system.
Having incorrect water pressure, whether it’s too low or too high, is problematic because it prevents the system from functioning correctly. Additionally, any appliances that use water can also face the effects. Low pressure makes it harder for a dishwasher to clean dishes, but high pressure can damage the appliance.
Complete Water Loss

When we turn on a faucet, we expect some water to come out, even if the pressure is a little low. However, if no water is coming out at all, that could be a sign of complete water loss. This typically occurs due to the following reasons.
- Pump Failure: A malfunctioning or completely broken pump can stop water from being delivered to the building.
- Electrical Issues: If the pump loses power due to electrical faults, it won’t operate, leading to a total lack of water.
- Severe Leaks: Major leaks in the system can divert water away from its intended destination, leaving faucets and fixtures dry.
- Clogged Pipes: Extreme blockages caused by sediment, debris, or corrosion can completely obstruct water flow.
Complete water loss is inconvenient to everyone in your building and can be a big warning sign that something else is wrong. For instance, if you lose water due to an unseen clog, the pipe could rupture or burst, causing extensive damage. The best course of action is to shut off the water and contact a professional to assess the situation and clear any blockages.
Visible Leaks
Leaks are another common sign that your building’s pump needs immediate repairs. As you inspect your pump room, check for water dripping from the system or for puddles on the floor. Note any leak that you notice, as even the smallest ones can impact the system’s pressure and cause damage.
Often, leaks indicate a loose fitting or worn seal; both components help maintain a watertight system. A loose fitting can allow water to escape at connection points, while a worn seal may no longer provide the necessary barrier to prevent leaks.
Frequent Cycling
Although your pipe does go through normal on and off cycles, it should raise concern if it does this constantly. In a properly working system, the pump will remain on until it reaches the set point, then it will shut off until pressure drops sufficiently to trigger a restart. If your system constantly shifts between on and off states, it puts excessive wear on electrical components, and this cycling issue can escalate into more significant problems.
Sometimes, frequent cycling occurs in response to other issues, such as a faulty pressure switch. This happens because problems with your pressure switch cause the system to send incorrect signals to the pump motor, resulting in incorrect operation. Faulty switches can either trigger the pump to start at inappropriate pressure levels or fail to maintain the proper pressure differential.
Rising Energy Costs
As you review your energy bills, take note of any unexpected increases in water-related energy usage. If your energy costs seem significantly higher than usual, it may be a sign that your pump system is struggling and in need of repairs.
A spike in energy consumption often indicates that the pump is running more frequently or working harder than it should to maintain water flow and pressure. By monitoring your energy bills and keeping a log of typical prices and water usage, it becomes easier to notice when something goes wrong.
Strange Odors or Tastes
If the water coming from the faucet or spigot smells or tastes burnt, musty, metallic, or like chemicals, avoid using it and call a pump repair team. Various smells indicate different things that we’ve detailed below.
- Burnt: Suggests electrical problems or overheating that can lead to complete motor failure and fires.
- Musty: Indicates microbial growth within the pump or distribution system, which can be hazardous to drink.
- Metallic: Indicates corrosion within the system that can cause damage to your health from heavy metals in the water.
- Chemical: Suggests contamination of some sort, whether it be pesticides, fluoride, or other organic compounds.
Keep in mind that odors and tastes don’t always indicate a problem with your pump system, as they can also originate from the freshwater source. However, it’s always better to have a professional inspect everything for peace of mind.
Sediment Accumulation

Visible debris or sediment around pump intake areas indicates filtration problems or system contamination that affects pump performance and water quality. Sediment buildup clogs impeller passages, reducing pumping efficiency and accelerating wear on internal components. This material can also damage seals and create leakage problems.
Sediment accumulation can be more common in areas with hard water, as minerals can precipitate out of the water and accumulate over time. To prevent sediment buildup, regular cleaning and maintenance are necessary.
