Problem with draining water through hose

I have a hose hooked up to my dehumidifier so I don't have to empty the bucket every day. I have it tightened very very tight, so I know it isn't leaking or anything. Yet the bucket is still filling up and the water is not draining through the hose. Does anybody have this problem?? Why isn't the water draining through the hose?

    Just an addition to the problem I posted - I exchanged the dehumidifier that was not working at Lowe's and I had the exact same problem again. So it was not just that one that was not working. Has anybody used one of these with a hose and it actually worked??

    I have the same problem with a new Frigidaire, 25-pint dehumidifier (model FDD25S1). I've hooked up the hose several times and tried several different hose washers (both the washer that came with the machine and a couple of different washers I had), but water continues to drip into the bucket instead of out the hose in the drain. The problem isn't with the hose, for I tested it by connecting it to a faucet; when I turn on the water, it flows out the hose and doesn't leak at the connection. But when the hose is connected to the dehumidifier, water leaks out from the connection into the bucket. The male end on the dehumidifier seems to be smooth, so that's not the problem apparently.




    If other people have the same problem, let us know. We may have to have a heart-to-heart talk with Frigidaire.

    Same problem for me. The bucket seems to fill up and I can't even figure out how that is happening since the connection is absolutely tight. My old unit would drain from the bottom of the bucket and when the hose would sometimes "back up" the bucket would fill and unit would stop. On this unit from frigidaire, I had a problem from day one. I even shortened the hose to make sure there were no problems on capillary action and such. Tried to call the company but they are closed for holiday.

    I BOUGHT THE SAME FRIGIDAIRE DEHUMIDIFIER ON 06/21/08-HAD THE SAME PROBLEM WITH WATER DRAINING INTO BUCKET INSTEAD OF THROUGH THE CONNECTED HOSE. I REPLACED THE HOSE AND USED 4 NEWW WASHERS. THIS DID NOT CORRECT THE PROBLEM. I RETURNED THE UNIT-THOUGHT THAT IT WAS DEFECTIVE, AND PURCHASED ANOTHER OF THE SAME-THE 25 PINT CAPACITY ON 07/08/08. WHEN I CONNECTED THE HOSE TO THE BUCKET, THE SAME THING HAPPENED- WATER LEAKED FROM THE HOSE CONNECTION INTO THE BUCKET- NOT MY IDEA OF A CONTINUOUS DRAINAGE SYSTEM. FRUSTRATED.

    Have the same problem. Has any of the recommended solutions worked for anyone?

  • Anonymous Aug 06, 2008

    I was having the same problem until I elevated the dehumidifier about 6 inches higher than the floor drain. Even though I thought there was enough head for the capillary action to work in it's original position, it seems that it needed the extra height. Give it a try and let me know.

    I have had the same problem with the 75 pint dehumidifier. Won't drain throught the hose. Even bought another new hose. Still fills the bucket. I have exchanged the unit twice and the same thing happens. Anyone have a solution yet?

  • mrmarketing Apr 05, 2009

    I have the same problem with the unit not always drainig thru the hose. There is surely a design problem here. I am online noe trying to find the direstions on how to get the bucket out. It is very, very, difficult, and I have sceen many others post the same comments. The machine seems to work well, but I spent the extra dollars for the extra capacity and not having to monitor the bucket.

I bought one of the FDL70S1 Frigidaire dehumidifiers today for my shop, and found that the $5 hose I bought to drain it through the floor wouldn't tighten down completely, allowing the hose to twist and wobble, a sure indication that it was not water tight. Simply adding a second washer, as described in another answer here, allowed me to tighten the hose sufficiently to produce a tight fit with no play between the hose and the dehumidifier. It hasn't leaked. I know it is a threads-per-inch issue, and I am stumped as to why Frigidaire would supply these units with a different thread pitch than the standard GHT (garden hose thread) 3/4" - 11.5 tpi. The threads on the unit appear to be 3/4 NPS - 14 tpi. Go figure!

Had this problem and the solution proved to be quite simple. The dehumidifier was not level. It seems that mine was designed to drain through the hose fitting and into the bucket. If I put a hose on it, then it drain through that. Very simple. BUT, there is a backup, so that if the initial drain get blocked for some reason, the water will flow through the backup and into the bucket.
This works fine UNLESS (and this happend to me) my floor is not level. So the dehumidifier was not level and the water went through the backup and directly into the bucket. I made sure the unit was level (or even tilted a little the other direction) and Voila! problem solved.
You may have other problems, but this is one of the basics to check.

This is a manufacturer defect in this unit ... there are not enough threads to tighten the hose washer against the unit. Add a second hose washer and tighten ... it will work fine. You need two hose washers.

I suspect that the threads-per-inch of the Frigidaire dehumidifier's hose connection is different (threads closer together) than a standard garden hose. My mother is having the same problem - I don't have the dehumidifier with me and can't confirm by measuring, but when I hooked up a hose to hers, this seemed to be the problem. The upshot is that you'd need a nonstandard connector to connect a hose, or an adapter that connects the nonstandard threads on the Frigidaire with the more widely spaced threads on a standard garden hose.

Please check this out and see if it solves the problem.

I had the same problem, but I solved it by applying a considerable amount of Teflon tape to the male hose connection on the humidifier and slowly tightening the hose onto that connection. I don't know if this was a threads-per-inch problem or not, but this solved the problem of water leaking into the bucket.

    I also had water dripping into the bucket rather than out the hose. But when I wrapped a liberal amount of Teflon tape around the male hose connector on the humidifier and then slowly tightened the hose fitting, everything worked fine.

The connection within the humidifier is too small for the plastic pipte extension. Wrap the end of the connection within the humidifier with teflon tape a couple times and then push the plastic tube back onto the humidifier. If it slips on easily, add a couple more layers of teflon tape until the connection is snug. My humidifier came with a sticky tape that came off the connection the first time I pushed the pipe on. I didn't realize it until I had your leaking problems. Raising the humidifier a little above ground level also helps the water feed into the hose.

If you are using plastic tubing (hose), you are most likely "air blocked". This is when air gets in the tubing and prevents the water from going around the bubble and the weight of the water behind the bubble is not strong enough to push pass. You'll see that others fixed this by raising the Dehumidifier (thereby increasing the head and the pressure behind the bubble). Also, just moving the tubing around to get the water flowing will break the bubble and in most cases (as long as there is always water in the tubing) will start to free flow normally. Move the tubing up and down until you see flow. (Only works on flexible tubing.) Piping is different and may need a vent.

I also thought the male thread was incorrect until I removed the cap that comes with the dehumidifier and tried it with a standard hose. It fit just fine. I had used nylon tape and also tried an additional washer but that didn't fit. Finally I checked the female end of the hose connection and saw the threads were mashed. Assuming the problem was on the dehumidifier end for years and dealing with occasional links today causes me a bit of embarrassment. But replacing the hose with one having a new female end seems to have fixed everything. Never assume...

Lay it on its back and take a good look where the hose is supposed to connect. The hose end is easy but the other end may have to be firmly inserted and maybe electrical tape secured so that the sensor " knows" water can flow from the compressor to the drain.

I have exactly the same problem with no water draining from the hose on the 50 pt unit. I used clear tubing, 1/2 diam, which I could see through. The tubing was about 3 ft long. It came out of the unit, ran along the floor, then up about six inches to go into a 3 inch diam drain pipe that came up out of the floor. The discharge end of the hose was about 3 to 4 inches lower than where it exited the unit, so I thought the water would drain ok. I saw the water coming out of the unit, and then fill the part of the tube that was on the floor (like a sink trap). Then I noticed air bubbles going through the water in the tube, back toward the unit. I think the fan was creating a slight suction inside the unit and drawing the bubbles in, preventing water from entering the tube. Then the bucket started to fill from water that fell through a small hole in another area of the water collection tray. Raising the unit up about 12 inches seems to have fixed the problem, but I'm not exactly sure if the height is the only reason that it worked. It might also be that it eliminated the trap, because now the hose slopes downward all the way to the floor drain, and has no place to trap water. So far, the bucket is totally dry.

I recently bought one of these from Lowe's myself, and bought the 25 pint dehumidifier, because it claimed to be able to accept a hose for constant draining. Well, when the manufacturer also sells larger capacity units, it's not in their best interests to make the  smallest unit drain an unlimited amount. The main problem is where the hose connector is situated. It's in such a tight, cramped space that you immediately feel like, " I should just get the larger capacity unit." Well, after emptying the draining tank several times---despite the attached hose---I finally decided that the problem is that you can't get a good, tight hose connection because there's not enough room to tighten the hose onto the threaded connector.
I realize that the hose was getting some of the water, but anything that dripped quickly filled up the 25 pint tank.
You either need to extend the point of connection to outside the dehumidifier, or find a hose connection that you can use a wrench on to tighten it. I'm trying a slightly different method. I found something at the hardware store that has a standard hose connection at one end, and the other end is a smaller threaded tip. I forced it into the humidifier's draining connector, and was able to attach a hose to the other end.
So far it's working. My next step would be to maybe attach a  PVC pipe that would fit inside that internal connection point, and  make it long enough to reach the outside of the dehumidifer. Then, attach a hose connector to that, then the hose. This can all be done using PVC purple glue, and the parts are in the plumbing section for just a few bucks. Better than spending  a hundred or so extra for a bigger unit.

Make sure there is not a plastic disk blocking the drain hole that needs to be removed.

Dehumidifier seems to be running fine, but water leaking on floor even with minimal water accumulated in bucket?


Hey friend, thanks for your post!

It sounds like your dehumidifier needs to be professionally cleaned. What could be causing the problem is a buildup on the inside of your dehumidifier where the water drains out and it is causing the water to not drain properly. Additionally, I would check to verify that the drain hole is tightly secured with the plug. I know you stated that the bucket is not leaking but have you removed it to verify? Please comment back if further assist is needed. -Matt

How do i make it continue to run with no bucket so it does not fill and and so i don't have to empty it


Attach a length of garden hose no longer than 5 feet, to the threaded drain hose connection that was supplied with your unit, to carry water to the drain.
1. Remove the drain-hole cover on the back left side of your unit.
2. Connect a garden hose to the threaded drain hose connector.
3. Push hose connector tightly to the drain-hole on Rear Grille with the arrow on the tab pointing UP.
The hose attachment will accept a standard garden hose fitting.
Do not over tighten the hose when connecting it to the hose connector,
use a rubber washer and tighten by hand firmly without stripping the
plastic threads.
When being attached to hose connector drain hose connection,
do not bend or kink the hose. The hose should lie flat from the
dehumidifier to the drain.

Is it possible to attach a hose to drain the water continuously without my having to empty the bucket every day? If so where and how do I do that? Thank you.


The easiest way is to put a hole in the bucket( by using a a hole saw) and attach a pvc fitting(male adapter with a rubber washer and nut) and hook a hose or pvc pipe that will drain the unit of its water. Good Luck

How do you hook it up to a floor drain?


With most portable dehumidifiers use a bucket to catch the condensate. Then the bucket is full the dehumidifier stops, then you need to empty it and replace the bucket to get the dehumidifier to start working again.

To make this unit run continually, the bucket can be modified so a garden hose can be attached and the hose can be feed into a floor drain. To do this look at the bottom of the bucket, there should be a hose connector where you can attach a standard garden hose. You will need to drill out the center of the hose connector with a 1/4" drill bit. Then you can attach the hose to the bucket and the other end into the floor drain.

The hose connector does not drain the bucket, it drains the condensate before it enters the bucket. Tube passes through back of dehumidifier by the cord wrap area. (you may have to remove a small cover)

When you install the drain tube, be sure that it is placed into the drain hole in the dehumidifier. You then will be able to "latch" the tube at the hose end by lowering onto the outer hole opening. This maintains a tight connection and the water will drain properly.

Drain problem


I have the same problem and after talking (mostly waiting) with Fedders repair, I have been told how to solve the problem. Plug up the drain hole on the right side (the one not connected to the drain hose). The drain hole extends down about 5mm, outside measures 10mm and interior measures 7mm. They do come with a drain hold cover. Not a replaceable part with a number. Off to the hardware store.
