How to Wipe Copper instead of Using Flush

- In this video, we go over why and how to use the pipe wiper instead of flush solvents on copper tubing.
We can use a pipe wiper to get rid of residual acids and old mineral oil without using solvents. Many manufacturers advise against using solvents because they may damage the system or cause negative environmental effects. In that case, it would be wise to use a pipe wiper.
The pipe wiper comes with pigs of multiple sizes (especially large sizes with the commercial kit). So, we pick the pig we need for the line size and use the pipe wiper with nitrogen (and a good flow regulator) to send the pig through the line. As the pig moves through the line, it wipes all of the oil and acid residues off the sides of the copper tubing. We finish off with a little more nitrogen to dislodge any particles that the pig may have knocked off the sides or dropped along the way.
When we retrieve the pig outside, we notice that it's discolored, meaning that it picked up some gunk in the pipes. One of the techs seals the line immediately after we finish, which will prevent other contaminants from getting in.
On the second go-around, we find that there is less oil than there was in the first pig. (However, we also discovered that Les ended up sending two pigs through the line.) The pipe is also bone-dry.

Excellent product for acid and excess oil contaminated lines.Thx for demo Bryan Orr who sweats POE..
"who sweats POE..) (that's funny, Brian)
Looks good. Hopeing there are no kinks in the line set. Or does the plug thing squeeze enough. I guess one could back flush
That is really cool!!!! I want one
Nice truck. And cool product I'm going to have to look into this
Joe Shearer I sold the truck last week 😞
HVAC School I looked at their site and I am going to order a couple pigs but they only show 7/8 and you said it does 3/4 too?
LOL!! Love videos that arent rehearsed. Real people saying real things. Although im sure some of the cussing was cut out. LOL!
Would it work on a package unit while I have the lines open and without trying to go through the metering device? I wouldn’t think so but have to ask.
Thanks awesome video keep them coming!
Very cool, I had a friend that worked in the petroleum industry and they would send the pigs from state to state as they switch what they are running through a pipeline. Later the pigs were equipped with devices to measure the wall thickness of the pipeline and line integrity. So one pig was doing many jobs at once. Maybe the HVAC world will get something similar just way smaller.
Very cool!
Nice product, However you could have talked about the pressure need to push this through,you could have talked about what's it comsite,looks like EPDM? IDK,COULD have talked about what happens if it should get stuck,do you put pressure at opposite end ? Did like the fact you showed multiple pushes. Great stuff,glad you bring it to our attention!!
This will help a lot. Installs
I would like to see the condition of pipe prior to they used this tool, wall of pip will near be that dry doesn't matter how much one wipe it, after all its oil and not water what we are dealing with.
If you had to braze a 50 foot vertical 1 1/8 AC line and then wanted to flush any residue out, would this work? Thanks!
If you go to the website (via the link in the description), there is a video demonstration which shows how solvent can be added before the wiper and the wiper removes the solvent as it pushes the solvent through the line. The wipers can be re-used or new ones can be purchased at an affordable price. I can also see how this system could be used to unplug a plugged condensate line by just using nitrogen without using a wiper (or you could probably waste a wiper and really clean out the condensate drain pipe. I could see this being used for a few different applications in our field. I can also see this being replicated with a few soldered line taps, copper, and rubber couplings from a hardware store and just order the wiper replacements.
Question. What happens when you can’t see the lines and there is a kink or sharp bend, or there is un reamed pipe? Does the pig ever get stuck? How much nitrogen pressure do you use. Is the pig a soft spongy material?
thats purity cool I will check into getting one but can you state the name or model # or what you are using please
So if i do a change out and im removing a R-22 unit going in with R-410A rather than using R-11 flush i can use this instead?
what material are these made from? they look like neoprene?
what about copper oxidization removal? you know that p.o.e. pretty much acts as a solvent and scrubs the piping clean. do you install a filter drier as close to metering device as possible?
That’s where a dryer should be installed, but everyone puts them back at the condensing unit. I like a dryer and a sight glass, right before the indoor coil.
Is there a possibility of part of the pig tearing off and staying in the line?
I like!
That looks like a great tool. I can only imagine how much that set up costs.
A clever DIYER could make one. It is really a simple device.
Ryan from arlinghaus! That's awesome
How much is the kit?
since every one works in their own way and method ,,,,,i always used acetone on cars , homes ,,,and never in 40 years did i get a call back because of dirt ,,,,,juts put it in the way you want to do it YOUR METHOD , add pressure YOUR WAY ,,,,and its done ,,,,but i do like this pig ,,,,,any technician with years or just good mechanical sense can come up with good ideas ,,,,,thanks
Looks cool, but the inside of that pipe still looked liken it was pretty black. The principal must be then to just remove excess oil? What about oxidation or carbon build up in there?
The pipe might still be discolored, but anything that could be cleaned off (loose scale or carbon) was done long ago, by the refrigerant circulating around in the system. That is unless their was a bad burnout.
Cool beans😎👍
It seems like a really cool idea but it would take to long having to add that much more extra work. And the material looks cheap they would have to get better material in the long run. Just my opinion.
🎵🎶 PAP WHAPER‼️ 🎶🎵
Seems like both pipes should have been reamed before blowing the pigs through. Looks like a great tool to have around though.
Bryan, your hands look dirty. Way to go!
Daniel Garska no... they aren't ... any soil is pretend
Are you still using it?
Every day
@@HVACS Thank you very much for responding.
My guess is that eventually R11 flush will be banned, like R12 & R22 have become.
R11 does pose some hazards.
It's vapors are heavier than air. & it displaces air, posing a risk of asphyxiation.
For this reason, it should never be vented into conditioned or confined spaces. If you use R11 flush, flush the line or lines from inside the building, through to outside.
& obviously avoid subjecting it to flames, hot surfaces, etc.
If you or someone on the job site is pregnant, then keep you &/or them from coming into contact with R11.
Lastly, R11 is Trichlorofluoromethane.
So it has that evil chlorine atom in it.
For this reason, it's blamed for putting a "hole" in the Ozone layer. (Lol, you can't put a "hole" in a gas. & even if you could, the surrounding pressure would just immediately fill it in. But that's a whole other topic for another time.)
I always thought that, but I could understand a gas density change, but presumably it would be a global change, not at a specific point...that’s like trying to put milk in your coffee but only in a portion of the cup
The Rx11 flush kit that is on the market has a misleading name. R11 was banned many years ago. I don’t think any of the flush kits contain any ozone depleting substances.
You still using this product?
Yes all the time
Let me play Devils advocate: what happens if the pig/mouse gets stuck, like if there's a joint in the lineset, or a slight kink and so on. Then you have a real bad day. I'm not being hateful and I really embrace anything new, but even if it works 95% of the time, it's the 5% that concerns me.thanks for the post. BTW am I being too overcautions?
Just blow it back the other way if it gets stuck
Also, if it does get stuck you learn valuable information. We have already found a bad suction line kink because of it that we wouldn't have found otherwise.
Excellent reply so thanks and good points.
If it gets stuck it must be like watching the toilet back up at your neighbors during a dinner party
Zach, at the dinner party, that's when you use the saying "it was like that when I got here"
No dangerous solvents .... maybe those solvents are to blame for Larry's, Bryan's, and my own expansive bald spots. We all could have a full head of hair if only pipewiper had come along earlier.
$500 for a couple corks, tubes and worm drive clamps. I could likely make this for about $10 if I actually wanted to use something this poorly engineered. I've seen a POS before, but this wins the golden POS award.
If you can make one then go ahead. It works great. You seem like a nice, industrious person. Maybe you will make $1000000000 dollars on your better engineered solution
I'll stick with the flush..
No way would I ever use this product. Too much risk of getting stuck in pipe.
We use it all the time... It's never happened once
I guess you could send the thing backwards, and taking note the smallest was 3/8, which I’ll go out on a limb and presume the pig product density would have tolerances to accommodate deformities, but I do wish there was a product that could expand copper internally up to a foot away, so many people hand bending tube and crushing it as it exits the wall...
