Should There Be Water in My Sump Pump Pit?

If your home has a basement or crawlspace, then we hope you’ve got a sump pump working behind the scenes to keep water from drowning these low-lying parts of your property. The humble sump pump doesn’t get much recognition until the rain pours, the groundwater rises, or a pipe bursts... but that can be too little too late.

Homeowners and property managers who want to keep their property safe and dry should regularly inspect the sump pump and handle necessary sump pump repair as soon as possible. One common issue is water pooling in the sump pit.

To be clear, standing water isn't cause for panic just yet. A little water might be normal - but other times, it’s a warning signal. We clear up the confusion in this brief article brought to you by Mr. Rooter Plumbing. If you'd rather have a plumber come and investigate, then call or message Mr. Rooter to speak with a live representative.

The Role of the Sump Pump Pit

Before diving into problems, let's cover the basics. The sump pit (also called a sump basin) is essentially a collection tank installed at the lowest point of your basement or crawlspace. When water collects in this area, it will flow into the pit.

Once the water reaches a certain level, the sump pump kicks on and pumps it away from your home. This prevents water from accumulating under your foundation and causing disasters like flooding, mold growth, or even structural problems.

A Bit of Water? Totally Normal

It’s completely normal for there to be some water in the sump pump pit. This is especially so after a heavy rain, snowmelt, or during times of high groundwater levels. The pit is, by design, a collection point for excess water. You can expect to see a small pool of water at the bottom.

The key is how much water is in there and how long it stays.

When to Worry About Water in the Pit

If you see that the water level is constantly rising and your pump doesn’t seem to activate, then you're dealing with a bright red flag. Similarly, if your pump is constantly running but can’t seem to lower the water level, then you’ve likely got a problem.

It's probably time to call for a sump pump or plumbing repair service if you notice:

  • Water nearly reaching the floor level of your basement or crawlspace
  • Pump not turning on despite high water levels
  • Pump running constantly without actually moving any water
  • Strange noises, vibrations, or foul smells coming from the pit
  • Frequent cycling on and off

These symptoms can point to a range of issues. It might be a clogged discharge line, a faulty float switch, an expire unit, or something else. It is always advisable to have a plumber investigate and restore protection in your basement or crawlspace.

Don't Forget the Maintenance

Sump pumps need a little upkeep to stay in fighting shape. You wouldn’t go years without changing the oil in your car, right? The same principle applies here. Neglect your sump pump and you might find it gives out right when you need it most.

Here are some ways to make sure your sump pump works when it needs to:

  • Test your pump every few months by pouring water into the pit and checking if it activates automatically.
  • Clean out dirt, debris, and any obstructions in the basin.
  • Check the float switch for smooth movement and function.
  • Inspect the discharge line for blockages or freezing.

As a final tip, we recommend investing in a battery-powered backup system. Why? Because the worst flooding often comes with power outages.

The Bottom Line

So, should there be water in your sump pump pit? In short, yes but only a little - and only temporarily. If water sticks around or rises too high, then your sump pump may be crying out for attention.

Give your sump pump the care and appreciation it deserves. Call or message Mr. Rooter Plumbing to hire a uniformed professional today. We are proud to offer maintenance, repair, and even replacement services. If you don't have a sump pump, we can arrange an installation as well.
