Can I Drain Dehumidifier into Sump Pump?

In order to prevent mold from forming in your basement, it is crucial that you get rid of excess moisture. One way to do this is by installing a basement dehumidifier.

Dehumidifiers help remove excess moisture from the air and can be hooked up to a sump pump for continuous drainage so that you don't need to worry about manually emptying it.

Can I Drain a Dehumidifier Into a Sump Pump?

Yes, you can drain dehumidifiers into your sump pump system. By connecting a hose between your dehumidifier drainage outlet and the sump pump, the dehumidifier will automatically drain when needed.

If you do not have a sump pump system installed in your basement or crawlspace, then this is something that you should consider implementing.

How to Drain Water from Dehumidifier into Sump Pump?

This process is very simple. Follow these steps to drain water from your dehumidifier into the sump pump system:

  • First, you need to turn off your dehumidifier (or simply unplug it)
  • Next, place your dehumidifier higher than the drain hose and sump pump because the dehumidifier drains water by gravity.
  • Locate the dehumidifier's drain hose outlet. This may be at the front, side or behind the water tank depending on the model.
  • Attach a garden hose to the outlet and run it to the sump pump. Then replace the water tank and plug in the dehumidifier.
  • Turn on the dehumidifier and start draining water into the sump pump.

Should I Drain Dehumidifier into Sump Pump or Sink?

There are a few reasons that you might want to consider a drain dehumidifier into a sink rather than your sump pump. For one, the water drainage will be much faster if you do this. You have to place the dehumidifier higher than the sink as well because draining it this way is a gravity-fed system.

Additionally, keeping a drain valve open on your sump pump can cause it to malfunction simply by wearing down the motor. 

However, there are also downsides to draining dehumidifier water into a sink rather than your sump pump. The main one is that it will be much more difficult to clean if there are any issues with mold or other types of debris.

Additionally, the water pressure in the drain line could create backpressure on your dehumidifier. Because of this, it is important to ensure that your drain hose has the proper PSI rating for maximum performance.

A dehumidifier with a built-in pump is much more convenient than having to hook your machine up to your sump pump or sink. Not only is it more convenient, but it's also much easier to install. All you have to do is plug your dehumidifier into the wall and connect it to a drain.

Plus, if you choose a model with a built-in pump, it will be more energy efficient. Most models with built-in pumps automatically detect when drainage is complete and will turn off the pump as soon as it does so. This ensures that you save as much energy as possible.

Even if you already have a sump pump installed in your basement, buying one of the best dehumidifiers with pump is still a good idea. This is because it will lead to less inconvenience and ultimately make your life easier.

Conclusion


Whether you plan on draining water from a dehumidifier into your sump pump or sink, it is important that you use the proper hose. A garden hose is ideal for draining your dehumidifier into a sump pump, sink or toilet. Make sure to check the PSI rating on your hose to ensure that it will not burst.

Of course, draining water into your sump pump system is not the only option. If you have a sump pump installed in your basement, then it may be still worth investing in a dehumidifier with a built-in pump. This is much more convenient than setting up an external pumping and drainage system. Plus, it will save you money on energy bills.
