M series humidifier tank leaks

If you have one of these, you may want to raid your cookie sheet storage, I found the 9x9 KitchenAid Fudge Brownie pan works just fine, I hope it doesn't rust out the pan

Another nice thing about it is it has high edges so if your cpap starts to float away from the leaky tank it won't end up on the floor

I did that too, but I added a piece of spongy carpet padding to absorb the vibration and noise, and put a paper towel over that to be sure I could tell if it was wet. The spongy padding can be tossed when wet, or at least alterated with another dry piece.
(I used more of the same padding under my computer to make it very quiet. It doesn't leak.)

I noticed the book that came with the M auto said to take precaution against potential leaking.

What is with the leaking, anyway? The reservoir seems sealed.

Intresting idea snoredog.

I did not realise how small the M is.

If it does leak, how high would the water go. Would it go high enough to cause damage to the machine?

Anyone using or considering buying the M-series, might want to read JeffroDoe's post on the ASAA website, regarding his company's meeting with respironics reps. Seems the DME supplier he works for is having numerous problems with the M-series.

I've alway kept a folded towel under my unit in case of leaks.
What's the first thing you noticed when the unit is leaking? (Wet nightstand? Wet water chamber? Water on heating plate?) How did you stop the leak?

Looks more like a warranty issue to me .... why can't folks just take the thing back and get a replacement until Repironics gets their act together.

If everyone starts using cookie sheets, there is no incentive for them to correct the problem and they will just use the profits to buy cookie sheet stock.

Yes, Dreamstalker, tha't what I was thinking. I do not want to use defective equipment!

If possible leaks & vibration noise are issues, a silicone baking pan might be a better option then a metal one. At least then there would be no rust and the silicone would be like putting something under the machine to absorb sound without risking blocking airflow as much as a towel or foam carpet pad could. I agree with DreamStalker though, then in the long run, the leaking is a manufacturing issue & you need to let them know so they can replace the HH tank.

Part of the problem is trying to figure out where the sporadic leaks are coming from. If it doesn't leak all the time, it's clearly not the bottom part of the humidifier tank that's leaking. Could be the rubber band-type gasket wasn't completely straight when the leaks occurred. I wasn't smart enough to check when my humidifier leaked. I guess what I'm trying to say is that it's not real easy to determine if it's a manufacturing/design defect or user error.

Lucky for me I have not had any leaks. I do clean my tank daily and make sure that the rubber gasket is seated well. It looks like this could be a real problem. The gasket is always coming off when I clean it and I have to make sure that I get it on just right.

One of the things I was told by my DME when I brought in my "regular" M Plus to exchange for a Bi-PAP and mentioned that my CPAP had damaged the table underneath it was that there could be condensation build-up at the elbow connection of the hose to the machine. And this build-up leaked at the elbow connection. Especially since my machine is below the mattress level so that the elbow was typically in an "up" position. I'm inclined to believe this because I never filled my humidifier tank above the fill line.

If moisture leaked at the elbow connection, wouldn't that mean that air was also leaking at the same point? Just wondering?

KimberlyinMN · Post by **KimberlyinMN** » Tue Nov 07, 2006 4:20 pm

True.. I guess I didn't think of that. Or.. Hmm.. Could it have leaked after I removed the elbow connection in the morning???

Well, I lifted my new 4 day old M series Auto w/Cflex last night to get the serial # off the bottom and there was this huge puddle of water, and on an antique night stand no less, and in an apartment I am renting!! So, I made sure last night, that I did not overfill it, which I had checked the first 2 nights to make sure it was not being overfilled, and also made sure the seal was not bent etc.....I had a NEW puddle of water under the machine this morning. What a mess. I have written Respironics and Cpap.com and I should be receiving a new tested humidifier container soon. The antique night stand, which now has a huge water spot, I am supposed to take up with Respironics....will see what happens with that scenario.

I don't understand releasing a machine with a defect like that?

Mine leaked. I put it on a cookie sheet from the beginning because I had read here about leaking humidifiers. There'd be two or three dime-sized puddles under the machine in the morning. I couldn't figure out where the water was coming from. The humidifier compartment was dry inside. Anyhow, my DME replaced the humidifier part of the CPAP, and the second leaked even worse. The humidifier stopped heating and the ramp stopped, both apparently from water damage somewhere. Then the DME replaced the entire machine 10 days ago, and there haven't been any more leaks.
