Hi, I'm Jay, and today we're going to talk about how to solve water leakage problems on your Aprilaire humidifier.

So let's talk about the possibilities here. You have water dripping from right here, ok that is a problem of the compression fitting. So the solution there is, turn the water off, cut this line back by like an inch or so, make a new connection here. You'll probably going to need a new ferrule if nothing else. You can reuse the nut, but you'll probably need a new ferrule, which you can pickup at a local hardware store. So that's if you have a leak here, another possibility is the valve body itself leaking. That's pretty rare, but it does happen. So if you have a valve body itself that's leaking, you need a new solenoid valve, there's no other solution. Another possiblity is, there is water dripping down your humidifier. So let's take the cover off this and take a look. Alright, so, lots of possibilites here with water dripping out of the humidifier. Normally, water should just trickle down the drain, but if you have water actually leaking out of the humidifier itself,  out of the case, most common problem is "I haven't replaced the pad in years." If these pads calcify up, they will turn into a brick, and water will overflow it, and leak into the bottom of the humidifier, and it'll usually leak out the bottom here, out of the seam on this cabinet. so if you have that situation going on, you just haven't done your maintenance, because this pad needs to be replaced at least once a year. Another one that's common is the feed tube here. These feed tubes are made out of a very rigid plastic. And this plastic will get brittle because it gets attacked by the chemicals in the water, and also the heat from the furnace. They will get this plastic very dry, and brittle, and will crack, so you'll have a little seam crack in here. And it's tough to see it, but it's another common failure. Although, if your feed tube is cracked, it's a simple replacement. We sell them, you just turn off the water and replace the feed tube. Another thing that is somewhat common, is this. This is the scale control insert, a lot of people call it a pad frame. Over time, these again, this is plastic, will get brittle because they've been attacked by chemicals and water. So, sometimes these will crack, that's simple. Buy a new one, replace it. Same thing goes with this top piece here, this is the water distribution tray, they can also get brittle and crack, easily replaceable. Another thing that happens over time, is right here, hiding inside this feed tube, is an orifice. The orifice is a little nylon piece that is about the size of an eraser on a pencil. So it is a very small component. It has a microscopic hole in it that meters the amount of water that comes from the solenoid valve, up to the pad. So, if that little orifice gets too big of a hole in it, it will feed too much water, up to the top of the pad. And you will have too much water coming down here and it will be overflowing and leaking out. So that's another simple repair. Just turn off the water, turn off the electricity, unscrew this brass nut, remove the old one, put a new one in. It's not completely uncommon for someone who has waited way too long to replace their orifice, to find that the orifice is actually missing, because it's disentegrated, and it's just blown the pieces of it, or the fragments if you will, up the feed tube, and into the water distribution tray. So, if you open this up, and you find there's no orifice in it, well it's because it completely dissapeard on you. So, obviously you just pull the old one out with a pair of needlenose pliers if it's still there, push the new one in, put it all back together. Another thing that happens sometimes is down here, there's a drain spud. And it's another piece of hard plastic, this drain hose is attached to. If you over tighten this hose clamp, you're going to squeeze it and split it. And it will wind up leaking right here. The drain spud for most models, snaps right out. So you snap the old one out, snap the new one in, put the hose back on, another simple repair. And that's about it for all the common issues for leaking out your humidifier.
