What size of hose or tubing do I use to connect directly to my de humidifier, to drain directly into a drain. Thanks. I have model DDR451

1. Make sure hose is not clogged or kinked.

2. Make sure humidifier is sufficiently higher than the end of the hose that drains and that no point in the hose is higher than the dehumidifier.

Please rate 4 stars if this is helpful. Thanks and good luck!

No, you didn;t miss anything. The drain tubing inside the hose connection on the back of the unit may be clogged. To solve this problem, turn the unit OFF & unplug it. Then disconnect the hose from the hose connection.

Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hose connection & tubing. Continue to push it in until you reach a bend in the tubing. You will need to gingerly work the Zip Tie past this bend, until it either bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip Tie back out while rotating (twisting) it. This will breakup any clogs. As you reach the inserted end of the Zip Tie, be prepared, as some water may follow.Reconnect the hose to the unit , plug the unit in and turn the Master ON/OFF Switch to ON. Set the humidity extraction level to 35% or Maximum if you have a manually controlled unit. Allow the unit to run, while you monitor the hose end for water flow. It may take 10 to 15 minutes for the water to start flowing, so be patient. Also, be sure the hose you're using is no longer than 48". Drainage relies entirely on gravity.

NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers.

Hope this helped you to solve the problem. Thanks for choosing FixYa.

This happens quite frequently. It''s due to a clog in the hose or the a clog in the hose connection tubing. If you unit has a float valve in the top of the bucket, be sure that it's not stuck in the UP position. To resolve clogging problem, do the following:

1. Turn the Master ON/OFF Switch to OFF and unplug the unit. Disconnect the hose from the unit
and check for clogs and remove them if necessary.

2. If no clogs were found in the hose, the clog is in the hose connection tubing. Use and 18"
long, plastic ZIP Tie, appropriately sized to fit in the hose connector tubing. Carefully insert the
Zip Tie or something similar (NO Wire coat hangers, though) into the hole and continue to push
it in until you reach a bend in the tubing. You will need to gingerly work it past this bend, until
the ZIP Tie either bottoms out or you run out of usable ZIP Tie. Then while rotating (Twisting) the
ZIP Tie slowly pull it out. As you reach the inserted end of the ZIP Tie, be prepared for some
water to follow.

That should solve the problem. Be sure the hose is no longer than 5 feet and that it slopes downward from the unit, with no kinks in it.

Hope this helped you solve the problem. Please let me know, Thanks.

Roren, once the hose is properly installed, it's not necessary to deactivate the bucket switch. Unless, the tubing inside the hose connection is clogged, the water should drain through the hose. However, the hose should not be longer than 5 feet and should drain down and away from the unit. As the drainage relies entirely on gravity.

If you have already tried this and was unsuccessful, the hose connection drain is clogged. You can use an 18" plastic Zip Tie, inserted carefully into the drain hole connection to loosen the clog and remove it. But, you'll have to gingerly work it past a bend in the tunbe, until it either bottoms out or you run out of usable Zip Tie. Then while pulling it back out twist the Zip Tie to dislodge the clog. As you reach the end of the Zip Tie, be prepared for some water to follow. Also, check the hose for clogs before connecting to the unit.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

If it won't drain thru the hose, but is draining into the bucket instead, the problem lies either in the hose or the hose connection on the unit. Either one of the other is clogged. Remove the hose first and check for a clog, If none there, it's in the hose connection on the unit.

Use an 18" long, plastic Zip Tie appropriately sized to fit in the hole. Or something similar (NO wire coat hangers, though) and carefully insert it into the hose connection opening. Continue to insert it, until you reach a bend in the tubing. Work it gingerly pass this bend, until the Zip Tie bottoms out or you run out of usable Zip Tie. Then, while rotating (twisting) it, slowly pull it back out. As you reach the end, be prepared for some water to follow.

Also, keep in mind the hose should be no longer than 5 feet and slope downward from the humidifier. It has no pump and relies entirely on gravity to drain the water.

Hope this helped you to troubleshoot and solve the problem. Please be kind enough to let me know. Thanks.

My DH 304 is a hand-me-down so I don't have a manual but it did come with a hose attachment which is plastic tube with a threaded end to which you attach a hose. The other end of the tube goes through a hole in the back of the unit and then through a foam screen inside the unit to slip over the drain plug. Aligning the tube and the drain plug can be tricky; it is helpful to remove the bucket to see if you're getting the tube onto the drain plug. Once you have the tube attached to the drain plug, align the tube in the hole in the rear of the unit so that the tab on the tube is inserted into the slot at the hole in the back of the unit.

I think that I am having the same problem, but I'm not sure that this tube needs to be plugging into anything. However, my humidifier seems to be draining out of this tube rather than from the tray into the bucket.

yep home depot get one with holes and a plastic tie will keep it in place

If you have the hose drain tube connected, drainage will defer to it first. If you remove the hose drain tube, the place where it connects to the drain pan drips into the container instead.

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!
