I have put in humidifyers for years but mainly on city water. Well I put in a honeywell bipass humidifyer about 3 months ago and just got a call today that they have water in the furnace room. I go out and sure enough the clear plastic drain that I run off the bottom of the humidifyer is plugged up with scum that finaly plugged so it ran over inside the humidifyer and out around where the drain hooks up. Now I have always notice a little scum in some of the drain lines if you get a low point in it and I try keeping as much drop in the drain lines as I can to keep the lines dry inside when the humidifyer is not running. This water going to the humidifer is from a well with filters on the water coming into the house. They say they have not had any problems with water to refrigerator drinking water or ice maker or anything else with water. The humidifer is mounted on the return so the supply air is connected at the 6 inch hookup. So tell me , why does this one have such a problem with scum build up in the lines? Could it be that its running so much that the lines never really get a chance to dry , hard to believe being just off the bottom of the humidifyer its a straight drop down and the scum is there too. The scum is sticky and not water deposits.....any ideas ? If I were to filer it , I would think it would plug filter fast but I dont see why its that scummy if its not the water anyway but caused by the heat from the furnace with the water. Give me some ideas other than thats why you dont put in humifyers lol THANKS
well I was hoping for a little more .....or I guess any ideas on the scum problems in the humidifier drain lines but I guess my explanation of what I see is probably not all that good and being it looks more like snot than water deposits I think it is more of a bacterial growth.
Thats a tough one I think I would disconnect it. I would not leave anything conneted that may be forming mold in anyones house, mold issues have risen to the level of CO issues. The only other thing I think you can try is to switch the tap from hot to cold or vise verse and see if it gets any better.

Running cold water and that is before the water softner being I have been told that I dont want the salts plugging up the pad. I am halfway tempted to put a filter like for a refrigerator water despensor on it to see if that makes a differance. I was told that the filters that the homeowner mentioned were on the water coming into the house are sand filters so I dont know if that would stop other things from coming in through the water. I would have thought you would see that scum in that filter but I was told that if you do not have air hitting the bacteria or what ever it is that it may not look like that until the air does hit it ,like when it is running down the humidifyer pad.
Water scum is apart of drainage,
I think the only reason humidifiers are the blame 1st is the fact that run a smaller drain size.
It's easier to plug up a 5/8" or 3/4" drain then a 1/ 1/2" which most house hold drain lines are.
It takes sometimes 40 yrs to plug a 1 1/2" main.
It takes about 2 yrs to plug a 5/8" line.
Water has minerals, that while they sit. They cause a sludge. If the H/O pures 1/2 cup of bleach in the drain ever yr they don't plug. Or have someone out ever yr to clean it.
Even 3/4 pvc plugs if you don't take care of it,
But it's bigger so it takes longer to show up.
