Question about Aprilaire 550 Humidifier

1 Answer

I have a Aprilaire 550 Humidifier. The feed tube is cracked and leaking. How do I go about replacing it. When I use a wrench to remove the copper end, will water come pouring out?

    I have the same problem - need to shut off the main supply line to the humidifier and remove the cracked line - I am having a tough time finding the line in our local plumbing supply stores...they are all recommending copper tubing specifically since mine is set up such that I have hot water going through my humidifier. If yours is the same set up - you must ensure to get the proper tubing for replacement.

Thanks for your question,
what you need is called an ( Ice maker kit ) any hardware store or appliance store should carry these, the copper tubing is 1/4 in, the kit comes with the service valve for turning on the water once installed, be careful, turning it on before the line is hooked will get ya soaked, it has compression fittings, make sure you dont cross thread the nuts when installing, you may have to shut the main water supply off to the house before doing this, the instructions are fairly easy to read, you can get 25ft - 100ft ice maker kits, you are going to need a tubing cutter and a cresent or box end wrench, and a big flat head screw driver, hope that help ya, lets us know, thanks again for the question,

Aprilaire 550 Changed the water panel and the water distribution panel. There is a little u-shaped cradle for the feed tube. But the feed tube is not secure and sprouts water everywhere. Now what?

On the water distribution panel there is an "L" shaped nozzle that the water hose plugs into, this directs the water into the top of the distribution panel. Your's is obviously missing. Look for this part on the parts you removed.

What is the saddle valve?

Your humidifier will have either a copper or plastic tubing attached to it. This tubing is the water tubing. If you follow that line to where it "taps" into a water line (near the water heater or a water line under your house), there should be a water shut-off valve. The water shut-off valve could be any type of valve but is normally a saddle valve. You could skip the step of shutting off this valve; however, it is good practice to shut the valve off for two reasons: 1. in the event of a water leak, you will be able to easily locate the valve to shut off the water. 2. if the valve is not "excercised" from time to time, the seals will dry rot and the valve will not be capable of doing it's job when the need arises.

Here is a video showing you how to trace your water line to your saddle valve. There is additional information on the video that you might find helpful as well.

What controls how much water flows into an Aprilaire 550? It was fine until a couple of days ago. I replaced filter, but it still appears to be too strong. It not only runs out the drain tube but is...

In the water line where it connects to the solenoid is an orifice. You can install a smaller plastic orifice or you can install a manual feed valve to where you can control the flow.

The unit leaks water on the floor

you need to replace the pad every season. if you are using a generic pad maybe more often. it also must be level and the drain coming off bottom clear. i suggest getting pads from . not the generic from hardware store. also if its got a black feed tube going from the solinoid valve to the top of the humidifier pad you may want to replace that aswell, they have been known to crack the new ones are grey.

Routing waterline to pad

1/4" flexible copper pipe. Tap into your cold water line using the included saddle valve (pierces the pipe), attach the 1/4" flexible copper pipe to the saddle valve on the cold water pipe and the solenoid valve on humidifier unit using the included compression fittings. Tada!

No water flow to the humidifier

Turn that pin to the left and that will open the valve to allow water to flow through it. If it starts to leak the all you need to do is tighten the nut that were the water is coming out with a wrench, be carefull it wont take much to tighten.
