My master let me put on this nice compression fitting valve today. I’ve done a couple of similar jobs soldering a valve in, but this is the first time I’ve done it with this valve. I then ran flex copper tubing up to the ice maker.

He said this is good progress for my roughly 6 months in. Really haven’t posted much here, so I’m trying to share more. Thanks for checking it out.

Good job. I hope you used dope on the ferrule. I put the nut on, dope the pipe, then put on the ferrule, then dope the ferrule, then screw together.

Make sure to always put the handle of valves on top or side, never on the bottom.

Why not the bottom?

I carry valves with bleeders, my handles almost always swing down. Occasionally I will put them with the bleeder pointing down at a 45.

When the bonnet/handle is upside down it can eventually seize. At least old valves, ball valves might not matter.

Looks to me like the valve handle is to the side in his pic

Um, I thought dope on the ferrel was bad. We just dope threads, which is just lubricate to assist in tightening.

I dope the ferrule, I use Megaloc dope for things like that. It's a thinner dope for lubricating rather than sealing. It does seal but I use a thicker dope for thread sealing.

Why wouldn't you put the handle of a valve where you can get at it to work on it. I never put a valve handle facing down unless I had to.

 

[Tommy plumber]

For six months that's good. I also put a little pipe dope on the threads of the compression valve to assist with snugging the nut. It's not needed on the brass ferrule.

What about the smaller 1/4" ice line? Did you use a brass ferrule? I don't use the brass ferrules on 1/4" or 3/8" compression copper. I only use the nylon {plastic} ferrules. { I bet this will spark a discussion...LOL}

 

[PlumbingNewbie]

Thanks for the comments. I did put a little dope on the threads and brass ferrule. Didn’t think it was necessary but my master does that too. The valve is installed on the side.

The customer had purchased a plastic supply line with the 1/4 nuts. I actually advised them that I had bad luck with the plastic hoses before, making the ice and water taste funny. That’s why we ended up with the flex copper line. Customer liked the taste and was happy.

If the valve is on the side you did a good job. Nice and clean. Your picture just makes it look different. Tommy, on the plastic ferrule on copper that really makes me wander about pressure on the pipe. I would think it could blow off but evidently not, since you do this all the time.

You'll have to get familiar with the code and also other various codes to see which tubing is allowed. Here they sell illegal fridge line kits that comes with aquarium type plastic tubing. I've replaced many as they eventually pierce and cause a lot of water damage. HD can sell all the illegal plumbing crap they want to the diy it'll eventually fail and I'll make money replacing it.

Make sure every fitting, tube or any plumbing material, fixture has a homologation stamp like UPC and up north CSA. Here you install non homologated stuff you foot the entire bill for damages when the house floods and they have to stay at the hotel for 6 months.

Another plumber on here a while back was doubtful about it when I said that I don't use brass ferrules on 3/8" copper tubing. So he tested it. He too thought that the nylon ferrule would allow the copper to blow out. But the nylon ferrule actually sinks into the copper tubing and dimples it.

Years ago I always used brass ferrules on 3/8" copper tubing and had leaks. Another plumber showed me the nylon ferrule trick. That was {20} years ago or so.

You do you, sounds like the nylon ferrules shouldn't be an issue. I remember the nylon ferrule controversy on here a while back.

That said MILLIONS of brass ferrules have been installed on copper tubing without leaks. I install them all the time. Just use dope on them.

Does your local code require a hammer arrest or on valves for ice makers/ fridges/ freezers.
Where I’m from, code requires a hammer arrester on any appliance with a solenoid valve - fast closing valve. That said, I believe Sioux chief makes a hammer arrestor that threads onto the outlet of the valve, with a female compression, then has a male compression on the outlet. At least I know that they have one for 3/8”

I use these Brasscraft sleeves AKA ferrules for 1/4 & 3/8 pex tube.

Thank you for the suggestion. There is no local code for the hammer arrester in that case.

Looks good from my house
