Is water removal a problem that prevents you from using a dehumidifier? Does the following scenario sound familiar
to you? To empty your dehumidifier, you have to carry a bucket of water from your
dehumidifier across the room and pour the water
into a corner drain or the laundry sink. Or even worse, you have to carry the water upstairs
and to your kitchen sink. This is a messy and time consuming process.
Then, once you put the bucket back in place, you may have to repeat this operation two or more
times that same day!
This scenario plays out every day for people who need a dehumidifier and during the rainy, spring months, our customer service
representatives are asked on a daily basis, "What can I do to make removing the water more convenient?"
You always have the option of purchasing a dehumidifier that has an internal condensate pump, like the
Aprilaire 1710A dehumidifier or any number of Ebac or
Dri-Eaz commercial grade
dehumidifiers. But if these are simply more than you need, don't fit into the decor of your home or are simply too
expensive, there is another alternative. At AchooAllergy.com, the best solution that we recommend is
to "port" the water from your dehumidifier.
Most people associate the word "porting" with computers
and something a ship may do, but porting is an important feature of most of
the dehumidifiers that we offer. Porting is the process of using
an exterior drain line to continuously drain your dehumidifier.
The porting process is fairly simple and works best when
gravity is on your side. The dehumidifier needs to be placed in
a position that is higher than where you want the water to end
up. If this is not possible due to a grade or a lack of a nearby drain, you can
still port your dehumidifier, but you will require a
to push the water up the grade or over a longer distance.
As mentioned above, most room size dehumidifiers, like our
Danby 50 pint,
have a condensate bucket that must be emptied by
hand. A float switch turns off the dehumidifier when the bucket
is full to prevent overflows. Many dehumidifiers provide a threaded spigot to
connect a water hose for drainage. If you have a floor drain or basement sink, you can port
the water to the drain by using gravity. Water is continuously being removed from the air, then into the unit,
and then down into the drain. You have very little day to day up keep or maintenance.
- The first
step is to decide where the dehumidifier will go and how you
want the water to go out of it. If you want to use the lower
cost of gravity you need to get the dehumidifier off the
floor and up at least a 6 inches off the ground.
Take 30 minutes to an hour to figure out the
placement of your dehumidifier and the final destination of
your drained water.
Make a quick diagram of how you are going to transport the
water from point A (the dehumidifier) to point B (the
- Place your dehumidifier on a level
surface. You probably
need to place it on a wooden skid or concrete block to
elevate the unit for proper drainage.
You might also build a small shelf to elevate the
unit. Use the
adjustable feet and a level to make sure your dehumidifier
dehumidifiers have a small hole about an inch or smaller
that can attach to a hose.
Some units may have a fitting or adaptor included to
attach a hose. Use
this to drain the tank by taking the end of a
standard garden hose and screw it onto the drainage pipe of
Run the hose down to your drain, sump pump, condensate pump,
or HVAC drainage line.
- Instead of a garden hose you also can use PVC pipe.
Cut and dry fit your PVC pipe to garden hose adaptor.
You can make a 90 degree elbow towards the ground and
another 90 degree elbow at ground level to funnel to water
to your drain. When
you are satisfied with the look of your drainage system,
glue the piping together.
Working with the PVC pipe and the glue
requires some trial and error, but the stuff is easy to work
with and reasonable in cost.
If you use PVC, the biggest thing you have to worry
about is how fast the glue sets.
When you apply the glue to the joint and push the
pieces together, you have only a few seconds before the glue
- Plug in your dehumidifier and you
should be ready to go!
Make sure that when you plug in your dehumidifier
that you do not use small or cheap extension cords. The
dehumidifier will use a lot of power, so you need to use a
heavy duty extension cord.
- Fill the
tank with water to test the setup and ensure it is draining
properly--do not pour water through the dehumidifier.
Testing the porting system might sound funny, but you
want to make sure it works properly before you leave it
alone for any length of time.
It would be frustrating to leave it and find out
later that there is a small leak.
If you see water leaking from a clamp or connection,
water proof the joint. If it is a fitting that was glued, apply some more
PVC glue to maintain a better seal.

Dehumidifier Placement, Operation, and Safety
Your dehumidifier must be raised to use gravity for proper drainage.
Put it up on a cement block or build a shelf for the
unit. Make sure that
the unit is level.
The next step is to determine how far off of the ground
you must place the unit to allow for effective drainage.
The unit must be placed higher than the drain to allow the water
to flow downward and away from the unit. This is referred
to as a gravity drain.
Most dehumidifiers have top-mounted air discharge and can be placed
against walls, but if you do not have top-mounted discharge,
make sure the dehumidifier is located away from walls and
placing the dehumidifier away from the wall, air can circulate
freely around the unit.
Always locate the unit away from sources of dust and dirt
which can clog the coils and grills.
This will result in better and more efficient operation
of the unit.
