Replacement integrated dishwasher not going all the way back

[Sheepdisease]

Use the gas flow knob to adjust intensity eg open it just enough for the flame to light and then back 1/16

Also leave an end open for the steam to exit on the pipe eg tap open / anything

Thank you, that does work. Although the blue flame either flickers like a candle or goes into flame thrower mode. So, twisting the nozzle does absolutely nothing then?

Around 49 seconds that’s the flame you want

Thank you!

So in the morning, I need to remove the pipe from the elbow and get the water below floor level out as much as possible.

What's the best way to cleanly remove the pipe from the elbow? Add flux on top first, hold the pipe firmly whilst applying pressure to pull it away at the same time as heating? How about afterwards?

Heat the elbow up, you will start to see it start to spit solder / little fire balls come from the elbow with your grips wiggle the elbow off if it doesn’t move give it a few more seconds then try again if it still doesn’t move tap the underside of the top joint with your grips up should move

Then use a fine file to remove all the solder etc

Then use a bit of Emory sand paper on a roll to sand it good to remove any last bits of anything

Right, I removed the copper from the elbow and was a bit shocked by what I discovered. I've no idea how this happened other than assuming I got the copper red hot and as I did that, the pressure from water residue blew a hole in it?

 

[Sheepdisease]

Okay, now I am concerned. I heated up the pipe and no matter how hot it got, it would not budge.

I tried again and it's still not moving. I'm basically left with no pipe to work with if I cut this away under the connector.

I think there must still be water down below. Even if you can't see it when the flame is on, steam can still be transporting much of the heat away. Can you dip a pipe-cleaner or other kind of wick to get an idea of the amount of water still in the pipe?

 

[Sheepdisease]

I can't even fit earth sheathing through. I'm feeling so stressed right now, if I could get the elbow off I would feel a lot better,

Looks like it may be plugged with solder. Given that this pipe has a pressure reducing valve on it further along under the cabinets it must be joined to the main supply - but where? There should be a stop tap or isolating valve that you're using to isolate this?

The pressure reducing valve has been removed and will not be put back. I've stripped it back to basics.

In the last photo, you can see that I can managed to remove the copper pipe from the elbow that goes to all the pipes in the house. So, what you see in the photos at the moment is the pipe, with a useless elbow on it that I need to remove, which comes from the main supply outside through the ground and comes up through the floor here.

I have the kitchen tap open, the outside tap open and there shouldn't be any pressure/water left.

I would have plumbed it all differently originally if it wasn't for the fact that we have a water meter. I'm guessing that could be part of the problem with moisture being retained as it doesn't generate enough pressure to allow movement through the meter? The meter is much higher up so at the moment any moisture is allowed to drop using gravity to the copper pipe that I have cut off and shows in the photo to the left of the elbow.
