Nice job Dave. Looked like a tight area to get to for the valve. I sweat out 95% of driers. I love the Super Techs that jump on every comment posted on any site to tell us what we did wrong but you NEVER see their work 🤣. We have all done things that weren’t text book perfect, that’s real world service. Stay cool.
They teach in school to cut out driers, but its usually such a pain in the ass its not worth doing. Lately though due to Acetylene shortage I have been cutting everything out to save on fuel. To any newbies reading, the reason why they dont want us sweating driers OUT is that you could release the moisture caught by the desiccant in the drier back into the system and the compressor oil, but if you achieve and hold a good micron reading at least below 1000 microns (500 is ideal I know) then there is a good chance there is no moisture. If you had a really wet system and you are routinely changing the filter drier to dry the system, obviously then would be the time to cut rather than sweat. The amount of moisture in an existing system is probably microscopic and insignificant.
Love your videos Dave I've been learning so much from you and HVAC videos my two favorite vloggers. I've just started applying for commercial/refrigeration I'm ready for the next chapter of my career after being 7yrs deep in the residential side of the industry.
I used that name once on a Campus Security Guard. Funny as hell watching him sit there and write it out as I spelled it for him.. "M, C, C, ...O, C, ...K, I, ...N, H, E, R. First name 'Barry', sir!"
What do you think about loosening the packing on the king valve? HVACR Videos always says that you should do it but I never do just curious on your thoughts
I do on my racks. I also put a dab of oil on the stem before I run them in and out. Just kind of an annual thing, definitely not every time. Oh and sometimes I just don’t care. If the packing ever leaks just back the nut off and wrap some Teflon in there and re seat the nut. Works every time 90% of the time.
@@NorCal-refrigeration I like the ones with the thin stainless steel connections, copper plated inside. Very little heat needed to sweat in. I used to get them from a huge ICP warehouse where I used to live on the west coast 25 years ago, but now all that's available around here is Sporlan, and Echo I think. So I just stick to Sporlan, they're ok, except the power heads rust in a cooler. They last forever in a freezer though.
🇺🇸👍💪❄ great video. ? When pulling a vacuum on low side with a solenoid valve u have to energize evaporator circuit to pull proper vacuum, correct ? N another way to do it without energizing the circuit would b to use solenoid magnet, correct ? Thanks again appreciate ur help. 🙏
The way I like to do it is to flare the new drier and sight glass in. Then next time you have to open the system up, you don't have to drag the torches, water, flux, ect on the roof, just 2 wrenches... I still sweat ac driers in, and self-contains they get burned in. But a refer unit like that gets flared, just makes it a lot easier for me at least the next time around.... But yeah, I don't hesitate to un sweat the drier, don't think it's a big deal.
If you don’t close the suction service valve and just trust the compressor’s valves, isn’t there a good chance of pushing nitrogen into the compressor when doing a pressure test?

Just spent more time at red light watching your video! Thanks for all the great videos!
Thank you

hitting the home stretch in HVAC school and I’ve been watching your videos a lot in my free time. appreciate the content man! 👍👍
Thanks for watching and I’m glad the videos are helpful. 🤘⚡️🤘✨✨✨
Excellent repair video, as always!🙂👍👍👍I do usually sing to the fittings when I put the flux on, "I'm gonna flux you up" 😉
Very well done señor super teck, thank you for sharing your great knowledge.
Great video Dave, always learn something watching you do a job. The finger bang tape measure worked out great, you did a bang on job.
Do like to share this video please.

😂😂
4:48 - I check my stuff on _new_ units, too!
great vid camera on ceiling in beer cooler ....
Thank you for sharing your knowledge.. always keep safe at work man.💌
Thank
Good stuff man. Like that opening jam too.
Thanks Dave
My pleasure
""How to Replace a liquid line solenoid valve"". Call Nor-Cal Dave. sit back and have a beer or case whilst watching. 🤣
You do a fantastic job everytime. Super tech.EasyMoney
I like using a flare or swage block to hold the pipe for the spin bits.
Great job Dave
I personally always seat my suction service valve. I don’t trust any valve whether there compressor or service to hold under vacuum. Good work.
damn dude! I want to apprentice under you
Yep round a bouts the way to go
Dave is made in USA awesome wants again
Gonna help someone for sure!
Nice video. Thanks man.
nice job +1
On the sporlan valve what’s the piece you were holding onto? Bottom part that sticks out. Is that some sort of adjusting screw?
haha you pulled a fast one LOL.
Hey if the solenoid valve is leaking around the adjustment screw will a brass cap with prong help seal it
no its a goner
What swage bits are you using here Dave ? Those are badass and swaged really good i have some cheap ones and they don’t do to good of a job
They are Amazon ones lol.
Now your left index finger is metric and the right index is standard , correct ? 😂🤣😅 Good vid I must say ... Thx for posting ...👍👍👍
😂😂😂😂😂
Nice job 👍👍👍👍

I never do.

Nice work Dave! Difficult to get sporlan stuff here, think they've had a falling out with the local wholesalers, they've all switched to danfoss.
Danfoss txv are the best.

Good 👍 👍
What does the flux do when you’re un-sweating something?
Keeps the pipe clean for re install

Why change out the whole valve ? You can buy rebuild kit for them.
If you don’t close the suction service valve and just trust the compressor’s valves, isn’t there a good chance of pushing nitrogen into the compressor when doing a pressure test?
Yes
Soy boys on the text book hunt.. hahaha
I would have brought it up to positive pressure with nitrogen before cutting the valve out.
Does the client really have cctv inside his walk-in ? Is he tryna catch the hard seltzer thieves out there ?
😆😆😆👊👊👊
Couldn’t you just unsweat the valve instead of cutting it? That way you don’t have to do that extra work
So let me ask what to you guys will be a stupid question: how do you evacuate the part of the system that was open? Through the suction service port?
Yep
@@NorCal-refrigeration why does the system need to be running when you’re vacuuming?
omg... you put all the moisture back in the system heating the old dryer... they're gonna sue your ass!
The fresh filter drier will catch the moisture... all 20 grains of it. 🤣
What the hell kind of box is that wooden that’s it can’t be up to code 😂😂😂😂😂😂
Just old pre code
