Why Is My Sump Pump Spraying Water? (Reasons & Solutions) 2021

We don’t always see the sump pump in action, but its value is nothing less than a first aid kit or fire extinguisher. We install a pump to get rid of an unexpected waterflood, but sometimes this basement waterproofing system goes completely south due to our mismanagement.

One of the major problems of the sump pump is that sometimes it keeps on spraying water everywhere instead of draining it. If this situation keeps up, it might damage other valuables in your basement unless you do something to stop it. These are a few possible causes listed below:

  • Faulty check valve
  • Loose connection between drain and pump
  • Malfunctioning pipe joints
  • Power issues
  • An overwhelmed pump
  • Product defect
  • Congested pit with dirt
  • Weep hole

There are several other reasons behind this occurrence; therefore, you need to figure out the disease of your pump. Let us see the possible causes of the sump pump spraying water and what can be done to avoid this unanticipated situation.

Sump Pump Spraying Water

Sump Pump Spraying Water: What Is Happening and What Can be Done?

Faulty Check Valve

Sump pumps are installed in such a way that its discharge line is initially inclined at an upward angle to direct the water flow through the exit point. Again, it is pitched downward to channel the water supply outside the home through the sewer pipe.

The check valve helps the process happen smoothly by preventing the accumulated water from coming back inside the pit or the basement. However, this one-directional process might fall flat on its face if the check valve does not work or gets broken.

If the check valve is unable to do its job, possibly one-third or two-thirds of water might jump right back inside the pit, making your pump work overtime. Eventually, the result will be spraying water all over your basement.

Now, how do you fix this water problem in your crawlspace? The very first thing you can do is to ensure a good quality check valve. Next, if it encounters any malfunctions, then it’s better you replace it immediately.

Besides, it is easy to understand whether the check valve is damaged or not by inspecting the pit. When the pit will be full of water and the pump’s getting exhausted quickly, you can safely assume that the check valve is damaged.

Defective Pipe Connections

The pump usually uses PVC pipes, which are made with proper care and technology. These pipes are compatible enough to endure leakage and holes.

But these PVC pipes might get cracked or loose from the drainage system in the course of daily wear and tear. In such cases, the water flow is disrupted due to leaks while running through the drain and ends up spraying it out.

If it happens to your sump pump, then at first, you need to search for leaks near the connections and joints. You can avoid replacing the pipe if the joints are loosened. If you see leaks over the tube, then the wise decision would be to purchase another one.

I had the same problem with my pump, but I tried to repair it rather than replacing it. Eventually, my efforts were up in smokes because after a few days, I noticed that the water was still coming out from those holes, and finally, I had to change it.

Therefore, it is better to replace pipes if you find any holes in them. Besides, as an alternative to PVC, you can try out cast iron discharge pipes. These are not unsusceptible to leaks, but then you have to consider the rusting issue.

An Overwhelmed Sump Pump

Every sump pump model comes with a certain level of power and capacity, and according to that, it drains out water from any crawlspace. But sometimes, you might notice that your pump is not consistent enough to discharge the volume of water coming inside your basement during heavy rainfall or massive flooding.

It is more likely to happen if your pump does not come with a higher discharge rate and motor power. Therefore, a less powerful sump pump gets overwhelmed when it has to deal with heavy water flow. Gradually, the pump can’t take the relentless beating, and you see spraying waters everywhere.

In this situation, avoid purchasing a pump without inspecting the ins and outs of its features. It is also essential to keep in mind how large your basement is and the approximate amount of water it takes during a rainy season.

Wrong Pit Size

The pit’s size is one of the essential factors to consider in water being sprayed out. If the sump pit is too small, then it won’t hold enough water inside it and eventually cause incessant water flow all over the basement. It is also not convenient to build the pit too large because the sump pump might eventually fill with excess dirt and clog with iron ore.

So, you can consider factors such as pump capacity and water accumulation per hour to know the accurate size for your sump pit. Besides, you can check the standard size according to the ability of a pump.

Defective Product

A faulty product is another reason why a sump pump sprays water.

There are a variety of sump pumps available in the market coming from different brands. Some of them are well-known for their reliability, and some are notorious among customers for the crappy service they bring. Products with subpar quality always end up being more trouble than worth. After a few years or months, you’ll face problems like spraying water and more.

So, you should jump the brand bandwagon if you want a safe landing. Other pumps can work, but the hit-and-miss risks are high.

Final Verdict

Sumps pumps are usually a blessing for draining out the water properly, but it is quite troublesome when the water flows back or sprays out in the basement instead of discharging it through the sewer system. Some of you may panic when you face this issue, whereas some might put it off to fix in the future.

But it is not the wise practice to do so because the more time you waste, the more damage can happen. Therefore, better fix your sump pump as soon as possible to get rid of spraying water in your basement. Don’t beat yourself up- follow the small blueprint- identify, know the solution (from any source possible), but most importantly- act immediately!
