Would have brazed a new bend in, nice to get the pipe more centred on the tray and also nice to be able to show the customer what the problem was. Just got one of those Knipex pipe cutter too, impressed with it so far!
Definitely mate, always nice to keep the evidence to show 👌🏼 I’m really impressed with Knipex cutters too, not the cheapest but you get what you pay for 👍🏼👍🏼
Cheers mate....from the other side of the pond. Ive been in HVAC for 22 years now. I like to see how other folks from other countries perform work in our trade
Hey mate , would appreciate a video of steps to pumping down and as well as reclaiming procedures on VRVs . Great work on field and your vids brother 👍 Jesus bless you
Came across this before at a large hotel chain in Scotland. Had to remove a section of the plaster board ceiling. Great work as always 👍 100% replaced the pipe for sure. Batteries ain’t gonna last long 🥴
Nice one mate 🙌🏼 Thats the first proper use with that set up but seemed to work pretty well 👌🏼 Really 😅 to be fair I think this one is about 6/7 years old too 👍🏼👍🏼
Manufacturers give distance's from branch selector boxes to 90 bend and fittings due to expansion and contacting of piping during operation. Leak waiting to happen seen this with brick and concrete in wall penetration's great catch 👍
Another option is to take just a small piece of pipe and cut alongside it. Put it around the hole like a mantle, then braze it. Gives a strong seal without all the cutting and double brazing.
I would have 100% brazed those leaks, bent the corners of that metal down so it couldn't happen again. Then I would evacuate, and charge the system. In the US you just don't walk away and say I'll have to come back when you could have gotten it up and running. But to be fair, I come from the supermarket side of the business, you don't leave until it's up and running unless the part isn't available. But it's interesting to see how it's done across the pond. Cheers!
You need to carry some ziplock bags and place your gauges in them when it rains, make a hole with the hook in the bag and hang them as you normally do.
Evening dude. I'm getting F-Gas qualified next month and would love if you can make a video for starter tool set if you have the time. Would appreciate it. Thanks
Great vid fam...j was hoping for link but I'll go looking for it...looks nice...I am currently using a YJ but I'd love to add another vacuum pump to my kit even though my current one still works great...lol @ the heel click to be fair
I was going to ask what you thought of the 500micron club. I was going to ref the Mitsubishi manual with the 5 tor. All the American guys bang on about the 500 micron but if the manual don’t say that why if not needed ??
A Deep vacuum is Allways needed ! Dehydration is critical to system efficiency , Rla , Performance , Compressor life & Compressors Run Quieter that have been evacuated overnight. I’ve proved it. Many times over 40 years of evacuations. The Deeper the Better ! I Shoot for 100 microns when possible. Under 500 if unit has to up ASAP.
I'm still instaling systems therefore still a while to go, it's nice to see proper vacuuming processes taking place. Can anyone please explain where the microns raise a little then drop down, what causes this to happen?
Nice Vacuum setup! Only thing I’d do differently is put both hoses on the suction line, one hose on each unit Then put vac stat on the liquid/discharge line I guess that way you can read the total system, at least through the closest IU to the OD Love the vids!
Great video ! But , I Do a Couple things differently. I Have learned a few things in the last 40 years doing evacuations. 1) I Have Found using a Vacuum pump isolation valve is a VERY BAD idea !!! They are unreliable & Leak Bad. They WILL DRIVE U NUTS & make u think u have leaks when u don’t. Use a Refrigeraton ball valve that u can buy at a supply house & Weld Male Flares on the ends. 2) To Save Time & Get a better job - Just hook up the Vacuum pump & Let it Run overnight. 3) Come back the next day & Fill her up. 4) Core Removal tools Leak - Don’t not use them when doing a decay test. They can have u chasing your tail. 😁👍 Great video though ! That Was a Fun one ! I Love it When You can Hear & see the Leaks ! So Satisfying !
@@hvacuk8975 I was thinking about it for a second. I believe u could just shut all valves on your manifold for a decay test since the guages read pressure when all valves are closed. It also takes pump hose out of equation.
Great Video, I mainly carryout installs and have come across a job that the client wishes to replace the cassettes but the condensers have been removed and the pipes left open, going to replace all the exterior pipework as it looks like a grinder was used, I discovered that there is oil in the cassettes, what would be the best course of action? many thanks in advance.
Gotta love the different type of refrigerant cans they give you. Here in the US they just began to stop color coding the cans, why? Good question, I think HVAC guys here need to storm the AHRI HQ and demand that to change lol. Nice video man, I like to see how HVAC is like in other countries, and I love how thorough you are. I'm pretty nit-picky with my vacs as well, I get em down and below 500 if I can. I use 2 3/8 hoses from appion, using their core removal tools, hell I got an old one of theres from 2018. Keep up the good work man, love it.
Thanks mate appreciate it 🙌🏼 So are all your cylinders going to be the same colour now then ? Believe it or not the core removal tools and bigger hoses aren’t very common over here ! Definitely the way I’ll be going forward though 👌🏼 Thanks for watching 🙌🏼👍🏼
@@hvacuk8975 They're all going to be gray colored, it's literally a nightmare to figure out which refrigerant to take out of your rack if you have a terrible memory like me lol. I mark the tops with the R-number. Hoping they revert, maybe... Also it's quite uncommon here as well, I've only seen like 3-4 techs use the big hoses for vacuums.
Mans getting hooked up by the mystical out of touch Yellow Jacket themselves blud , that is amazing matey ! The one thing I would do different is remove the core depressor on the 1/4 " end of the 1/2" hose , one less restriction in the line . Man I'd love to get my hands on that gear bro , good on ya 👍
Love the Yellow Jacket kit mate 🙌🏼 Lucky to get to try it out👌🏼 That’s exactly what I did, whipped that depressor straight out 😉 Thats one of the good things about the Yellow Jacket hoses, easy to pull them out 👌🏼 Hope your well mate 👍🏼👊🏼
Another great vid,I have the testo digi manifold but that yellow jacket Titan looks the s...t.Have you had any experience with the crimped pipe fittings I have just used them on a no braze site and was a bit apprehensive but have to say there amazing keeps the pipe clean and there quick,downside is the tools expensive and the fittings are too but I’m sure Rothengerger can send you some to try for a future vid😁
Thanks mate, appreciate it 🙌🏼 I haven’t actually, I used to be a bit dubious like you but all I hear now is positive reviews ! Funny enough I tried to borrow a crimp tool for this video because this would have been a perfect example, especially as sites are now funny with hot works like you say ! They are expensive but could be a worthy investment ! I’m all up for reviewing some 😂👀👍🏼👍🏼
I would have definitely brazed those grooves and notched the tray so it wouldn't happen again and finish it in one trip unless I needed more refrigerant not come back twice.
I am new to HVAC and this is very helpful, got a question although it may sound very dumb so please excuse me. As you have the nitrogen purging through the system, do you leave it purging through during the cuts? How does that work?
Thanks mate 🙌🏼 I got them imported from the US, I think it was through eBay 👍🏼 I have heard there is somewhere in the UK that can get hold of them though
How did you charge the system without losing the vac as you didn’t use the manifold would you not lose the vac on the lines when removed from vacuum pump 👍thanks great video
You connect the manifold to the core removal tools. Hook up your refrigerant to the manifold and then purge your hoses. Zero out your scale and start adding refrigerant by opening up your core tool. After you are all done then you will shut off the CRT and hoses and install your cores.
Hey. Do you work on a lot of Mitsubishi? Maintenance tool? Have a unit that I can’t seem to figure out and neither can tech support. Would love to hear your input.
I do work on a fair bit mate ! Yes, I’ve got the maintenance tool too. I can definitely try and help, what problems have you got ? Drop me a DM on Instagram if you want mate 👍🏼
Yeah it did go up and down a bit 😅 Never ran out though mate to be fair and I hammered them all day ! They are rechargeable with a micro USB lead too which is a bonus ! Much rather them be rechargeable than have throw away batteries 🙌🏼👍🏼👍🏼
I recorded it all with the camera the wrong way around for on here 😅😅 I’ll try and maybe get it edited for on here though as it was a good test to be honest 👍🏼👍🏼
3 visits in total when could of completed in 1 annd half days by welding over the holes and just cut out the corners of the cable tray so it dont rub through the pipe again saving the customer 12hrs cost of on site work 👍
Not been working in HVAC long, these videos are a really helpful watch. keep up the good work 👌🏼
Glad they help mate 🙌🏼👍🏼 Thanks for watching 👍🏼👊🏼
Would have brazed a new bend in, nice to get the pipe more centred on the tray and also nice to be able to show the customer what the problem was.

Nice equipment you’ve got there mate!
I had a similar leak, 1 1/8 pipe hanging off the end of some cable tray, took 6 years but the leak still came 😁

Amazing video buddy, so much knowledge and attention to detail. Keep up the good work mate
Thanks mate 🙌🏼 Appreciate it 👍🏼👍🏼
I agree with you use another piece to ensure it falls in the tray

Derbyshire Refrigeration got the Yellow Jacket evac kits. Comes with tool + 3/8 x 1/4 hose.
Hi there can I ask where you got your core removal tools and your half inch charging hose?
do you only do aircon or refrigeration aswell?
How did you charge the system without losing the vac as you didn’t use the manifold would you not lose the vac on the lines when removed from vacuum pump 👍thanks great video
You connect the manifold to the core removal tools. Hook up your refrigerant to the manifold and then purge your hoses. Zero out your scale and start adding refrigerant by opening up your core tool. After you are all done then you will shut off the CRT and hoses and install your cores.

I would have defined replaced it and I don't know why people leave pipe on tray like that see it all the time.
The battery looks to be all over the place on the digital manifold up and down like a yo yo?
Yeah it did go up and down a bit 😅 Never ran out though mate to be fair and I hammered them all day ! They are rechargeable with a micro USB lead too which is a bonus ! Much rather them be rechargeable than have throw away batteries 🙌🏼👍🏼👍🏼
@@hvacuk8975 ahhh okay cool, I did wonder if it was just an odd reading on the basis it made it though :) good to know 👍
Definitely would have replaced it the way you did. That pipe was way too damaged. Good job
Where can I buy that yellow jacket gauge manifold
Nice work.
Thanks mate 🤜🏼🤛🏼
5:04 where do i get this pen from :-)
It’s a Yellow Milwaukee Inkzall Pen mate 👍🏼👍🏼
Hey no more vids?
Howwww many £'s in refrigerant!? :O
What do you use to braze?
I used Oxy-Acetylene for this with a pepper pot head on the torch. Think my welding torch kit was from BOC 👍🏼
How do you get into HVAC?
Hai
Not on the 'gram. I'd like to see you vac test though.
