So today, we're here working on a walk-in freezer and the complaint is, is that they've got ice all over the floor. So super nice in this corner we've got a giant puddle of ice. My assumption is, and we're gon na pull this insulation off. That we've got a broken drain line with a busted drain line heater.

It doesn't sound like it's frozen, but we're gon na go through it and try to figure this out. So my assumption is that's here in this corner, because we've got a large accumulation of ice and unless this floor was extremely unlevel, it could be dripping over here and running this way. But I don't think that's the case. So I think that we've got a busted drain line right here, because if you look up to the top of the walk and it's not coming from, there doesn't look like it's coming from the drain: pan.

Okay, so we pulled off the insulation and look at what we found right in the corner where we thought it was going to be so. It looks like the drain was plugged up. It's actually not plugged up right now, though, so that's interesting, so we're gon na get this thing repaired and then I don't care if this heater is good or not, we're gon na go ahead and replace this heater door to it just to be safe, because we Don't want to have to come back on this, we'll inspect the rest of the pipe and see we may just replace that section right there more than likely and obviously get a water hose on this and blow this drain out. Okay, so we pulled all the insulation off we're gon na go ahead and redo this whole drain line, because we found several breaks in it.

If you follow it, we're looking okay here, but once we come down here, we've got this break. There's another break. There's another break over here like it's just multiples, there's one down there, so it's gon na be easier for us just to cut this drain line and redo it all we'll put a new heater on it. Like I said, and then the trick is that we're gon na take as this is a three quarter inch drain line, we're gon na take ancient and 8id insulation, and it's gon na fit perfectly over this and seal perfectly over the drain line heater.

Instead of trying to wrap three-quarter inch insulation so we'll get that going right now, so we're gon na start just demoing this. If we tried to just repair the pieces, it would take us longer and also this drain. Peter has memory in it now, there's been wrapped. So long so when we try to rewrap it, it's just going to be a nightmare, so we just I brought all new stuff.

So so we got the drain line all taken out, and this is what we're finding once we get over here. It's actually frozen right into here too. So what we're gon na do is go ahead and drill a big enough hole through the wall that our insulation can actually run through, or at least the heater can run through and we'll wrap the heater all the way through into the walk-in cooler here, a foot Or so this is a walk-in cooler over here and that's our drain line coming through right there. So we're gon na make it big enough to where the heaters can actually come through.

So we're just getting ready to pipe this. We did our best to get the ice up off the floor and then we went ahead and drilled the hole big enough. We're not gon na push the insulation through the wall, but we drilled it big enough to where we can push the whole drain line through the wall with the heater around it and then we'll connect it on the other side and insulate both sides of it. So and then we'll spray foam that to seal up the penetration that way, we can actually get the heater running through the wall, but you got to make sure that your hole is big enough, that the heaters not going to touch so it doesn't shore it out Or anything so now we're just gon na mock up the pipe.

So you can see we put the end on there and then we wrap it about every two and a half three inches zip tie it it's going through the wall, we're gon na insulate it. This is going into the cooler, so it doesn't need to run the full length just needs to. Basically, if you can penetrate as much after the wall as possible. Okay, so we got it all wrapped around.

It was a two-person job. It was a pain in the butt. You notice that, as I get closer to this corner, I go tighter on my turns, because I want to keep the corners warm it's my personal preference, then if I pan out you see it separates a little bit, then, as I get up to the top corner, I keep it a little bit more go right up to here and then I'm gon na go ahead and put an end cut on here and then we're gon na run it into this coil. We'll get that ice up there defrosted too we're gon na hook it to in and for because I want this thing heating the drain line when it's in the freeze mode, personal preference.

I don't see the point in heating it when it's in the heating mode, because the water's coming off the coil warm and dripping down the drain line. What I want that heater and my theory is, is I want that heater to heat any spots where we might have a slow flow and it might freeze so now we're gon na insulate it and hook the end kit on it. So I came up into here. I insulated all the lines like I said, inch underneath insulation, so it fits perfectly around there.

It seals off the pipe we're gon na put a support, strap on here. The heaters ran, it's hooked up, it's hooked up to four and in terminal, so it runs in the freeze mode. It's running right now I get one amp across the heater, which is good. We're gon na give this ice melted and get this unit into a defrost.

While we're cleaning up there's some ice on the other side too, and that's it so we're just kind of in cleanup mode down did really good insulating everything. So it's nice and good. We can run and expose like this a little bit. It's not a big deal.

It doesn't get burning hot or anything, it's just a very low, so we're good, just kind of clean it up. So we got the unit in defrost. Now we're just gon na test the defrost heaters you notice, you've got heaters running to the back, so the top two black lines touch a minute. There's your heater.

So this these top two is one heater. These two are one heater. Those two are one heater and then there's also a heater in the pan. So altogether one two three: they have four heaters in this thing and you want to see amp draw across all of them and I do so we're good.

So just put your clamp on there tests and draw don't let it touch the heating element, good, good, good, good. Okay, all right! So we're getting this thing back together. We've got their fries back where they go we'll. Let them do the rest of their organizing, but we are gon na dig into this, because the side of this thing looks like it's all: frozen up and there's giant cracks and the blades old school blades.

You can see they'll, probably change that blade out form. It's been hitting the ice as what it's been. Do it there's ice in the expansion of section real good, so they get it right up in there y'all back in there. So we'll get that ice taken out defrosted, it's draining like it should be.

We have it in a long, deep boss temporarily. We just took the X terminal off the defrost clock and put it in a 50 minute defrost. That way, while we were kind of putting things back together, it would just you know, get some of the ice out. That's it.

I think we're gon na call this one quit be done. The ice in the expansion valve section more than likely was from a freeze up that someone never got into the side over there because it's not on any other parts of the coil. So all right, so this was a service call on a walk-in freezer that had ice all over the floor. The customer had called and they were just complaining.

So when I came out, I kind of had a hunch, and this was actually the second time I'd been out. I'd been previous to diagnose. I had brought back this time heater, cable and everything that I needed, because I had a really good idea that it was a busted drain line and my suspicions were confirmed, as you guys saw in the video once I went ahead and pulled all the insulation off. We found multiple breaks in the drain lines, so it was just easier to go ahead and replace everything and start from scratch, as opposed to trying to repair all the broken spots.

The labor would have been just you know just about the same so so we went ahead and replaced the entire drain line, replaced the entire heater and then re insulated. The entire thing and, like I said in the video, my personal preference, the heater, is wired up to the cooling circuit, so 2 4 and the n-terminal that way the heater runs when it's in freeze mode and then when it's in defrost mode, there's no need for The heater to run because the water is warm dripping down the drain line. My theory behind that is, is that just in case there's a low spot or something like that in the drain, or even a slight restriction. I don't want that water to freeze, essentially okay, and it's only gon na freeze.

Theoretically, when it's in the freeze mode. You know, I guess it's possible in the heat mode, but you guys get the point. Okay, that's it! It wasn't anything too technical. It's just a time consuming job these drain line heaters you just kind of take your time and do it right.

Wrapping them is kind of a pain in the butt and then also, if you've ever done, the cut-to-fit drain line heater. I think it's made by Ray pack, you, the end kits, are kind of silly too, that you got to follow the procedures and the instructions thoroughly to get the end kit you know, put on there properly and then the electrical termination, on the other end put on Properly but other than that, that's pretty much it guys. Okay, hey! I just want to say thanks a lot for taking the time to watch these videos. I really appreciate you guys doing that, and I really appreciate the feedback you guys have been leaving me.

I've been getting, you know, video requests and I will say, video requests are a little difficult for me because I film these, as I get service calls, I don't go out with the intent of finding a service, call that I can film a certain particular video. You understand what I'm saying, so you know if, if, if you guys make a request, you know I'll keep it in mind to try to film one of those if I ever come on it, but it's not like. I can just go film that video. I do.

These, like I said as the service calls come in, but thanks a lot for that guys, and you know right now. Next to me, you'll see some other channels that are popping up. I suggest you guys give those channels a few and maybe consider subscribing to them. They got some great content out there and we'll see you guys on the next one: okay,.
