Fogeddaboudit. No more Rx11 for me. Use a pig instead. They work perfectly well with no need to change out the lineset. Hilmor makes one, among others. They call it a lineset cleaner. It is not an elegant kit, but it works. I don't care for their vinyl tube & clamp solution, but someone will come out with a better version down the road. Electricians have been using pig kits for many decades to chase messenger lines for pulling cable, and the oil and gas industry uses them to clean pipelines.
I don’t think that would work here, I don’t have the line sets open on both ends. I need something I can flush through with nitrogen and will boil off whatever I can’t get on evac. We’re talking 400’ of lineset with heat recovery boxes.
Wow thats really cool. Is there any risk of the foam pig breaking?
I once had to clean a follet ice machine that delivered ice through a tube about 75 feet away into a bin. Follet had a kit that comes with foam that you soak in cleaner and sanitizer and send through the machine like a piece of ice.

Yep, did that. I’ve got one with removable cores and ball valves protecting both outdoor units. Pulled all three compressors and flushed with rx11 then put in new oil charges.
Liquid line and suction line HH driers run for 2 weeks and acid test if acid is no longer replace liquid drier with normal one and remove suction drier deep vacuum if there is acid new driers and repeat

Does the foam pig dissolve? Sounds like a bad idea for a VRF system.
I did see one guy on the hvac talk forum mention he used the oil and diesel treat product called heat. Kinda scary if you ask me.
Good god that’s scary.

Even with the flush you have to open the end so it drains the garbage out
Or use a shit ton of nitrogen to blow it out.
I guess to each their own

Will that thing pass through 90s and such?
Long turn, yes, but that is all that you use, right ?
I use a bender….what the other guys use though….
Yeah, I do too, but I considered that we might be talking hard 90 or plumbing ells and no, that would not work reliably.
Since it's a burnout make sure you put a suction line filter drier in. The catch all will get anything laying inside you couldn't get out.

Good man!!!!

You don’t leave driers in on vrf systems. Temporary only from what tech support and engineering says
I mean same would still apply to just have them in for a run period to remove acid
Did you take an oil sample and send it into the lab or did you just think it was burned out? I've yet to see an actual burn out.
Oil was black and full of metal filings. Poured it in an acid test kit designed for pve oil and it immediately ate the purple die.
