Many households keep dehumidifiers connected in and running all the time since high humidity encourages the formation of mold in the home. A bucket at the back of the machine is filling up with water while the motors whirr. You’ll need to empty your dehumidifier bucket every few days, but with a few basic tools, you could allow your sump pump handle it for you. How to drain humidifier into sealed sump pump will be explained in this post.

Draining Dehumidifier into Sealed Sump Pump

Mold and fungus are kept at bay by dehumidifiers, which remove excess moisture from the air. Mold spores are common in cellars and crawlspaces, thus these devices are often seen there. A dehumidifier container should be drained every day or two, based on how much water it has absorbed from the air. You may avoid emptying the humidifier by connecting a pipe and allowing the water to flow into a sump pump.

You may apply either a 2-inch or 4-inch block, based on how far you need to lift the device.

Draining the dehumidifier begins with turning off the machine’s electricity and removing its bucket from its back. Create a hole in the dehumidifier’s container’s rear wall next. If at all feasible, the opening should be located as near to the container’s end as practicable.

Push the hose end through the opening until there is approximately an inch of pipe left within the dehumidifier’s storage bucket. Extend the silicone pipe and coat the dehumidifier’s container and hose with a thin layer of the material.

Make sure that the other side of the line is connected to the sump pump. Flow the sump pump hose into the sump pump port. The hose must go downward and must not extend over the dehumidifier drain connection at any point. Change the bucket that collects water. Switch the device back on once you have reinserted the dehumidifier’s container and ensure that it is securely fastened.

Draining Water in Sump Pump

In earthquake-prone areas, sump pumps are essential for removing the excess water that collects in the basements of most houses. If your sump pump fails and water begins to back up, you’ll need to act quickly to fix the problem.

Because you can’t use the municipal sewage system to dispose of sump water, you’ll need to do it yourself. As time passes, more damage will be done to your basement, belongings, appliances, and technological equipment.

Stains and a musty smell may be caused by mold and fungus development in a damp basement, which is why it’s important to keep the area dry and clean. The sooner you dispose of the water, the safer.

An essential role played by a sump pump is that of removing standing water from your residence. Because of this, you don’t need to empty the sump pump of water. There are few options available if your sump pump malfunctions.

You may use a hand mop to clean up any excess water. Empty the bucket outdoors after depositing the water in it.  Drain as much of the excess water using the bucket, then utilize a mop to eliminate the remainder. Dispose of garbage at least 20 feet apart from your home to prevent it from seeping back into it.

A wet/dry vacuum may be used to remove the water, which can then be disposed of in the open. A wet/dry vacuum that has a capacity of at least 5 liters is the best option for this work. Unload at least 20 feet apart from your home.

Drain the water from a manual pump if there is no electricity. To begin, place the hand pump in the sump pump’s opening.  To use the hand pump, connect a garden hose to the pump’s threaded outlet. Adjustable pliers may be used to ensure a watertight seal. Pour water from the faucet out the windows 20 feet from the home.

Draining Dehumidifier in Crawlspace

An important consideration when setting up a dehumidifier in a crawlspace is where to route the moisture. If you have a crawlspace, you certainly don’t want water to accumulate there. There are two appropriate ways to achieve this. Gravity drain systems and condensate pump systems are two options.

Gravity Drains

Condensation is channeled out from the dehumidifier using a gravity drain. Sufficient moisture must be removed from the basement by running down the basement wall and out the drain. For the liquid to discharge effectively, you just need approximately 1/4 inch of a drop every 10 feet of flow.

It’s imperative that you exercise caution and prevent any lulls in the flow. Having a dehumidifier installed in a crawlspace is a waste of money if the water backs up and floods the area. Additionally, the dehumidifier may be harmed by the backflow.

Condensate Pumps

If you have a dehumidifier, you’ll need to use a condensate pump to remove the moisture from the air. In order to compel water to drain out of the crawlspace and terminate at the termination point via a drain pipe, a pump is activated by a float switch when reservoir levels reach a certain level.

It’s a good idea to check if you have sufficient room in the crawlspace to put a dehumidifier elevated enough to enable for appropriate drainage into a condensate pump reservoir before finalizing the choice to utilize one. Installing an improperly installed condensate pump might cause water to back up into your dehumidifier and pour over your moisture barrier.


When you have a sump pump put in your basement or cellar, you absolutely need to have a dehumidifier installed as well. Drainage of dehumidifier water is made simple with the use of sump pumps. This article explains how to drain dehumidifiers into sealed sump pump. We hope that this may be of assistance to you in maintaining a clean and dry environment in your area.
