Weeping joint on rising main

I see my options, in descending order of difficulty as

1) Replace the joint
2) Attempt to remake the joint with a blowtorch

First find your blow torch.

The pipe or elbow fitting was not properly cleaned when originally assembled and soldered.

You don't really need any new pipe or a new elbow. Simply unscrew the compression joints either side, remove the elbow and pipes, clean, resolder twisting the upper pipe in the elbow and reassemble.

Job done!

Thanks Russ.

There is already a drain off fitted. You can just see the very end of it in the photo towards the right.

That will drain the rising main leaving only a little water between the pressure valve and stopc0ck.

It would be useful if you could give the reason for that.

Is there something wrong with bending a pipe through 90 degrees, provided the radius is large enough not to cause a problem?

I have seen plenty of plumbing with pipes with similar 90 degree bends. Is that bad practice?

It's as in my post above chap, there is not enough space to bend the pipe, you need to use fittings/elbows/

Look believe me I am the worlds greatest advocate of bend V elbow to aid flow and cheapness, bend every time, but in this case it can't be avoided.

Plus, I really am trying to help, even if my blurb isn't getting across;);)

Sorry, I disagree, trying to clean old failed fitting really is false economy, a couple of quid for new, provided our man can find his blowtorch:A:A:A:A:A:A:D

How did I know that you were going to post that!

Sorry but I disagree with you and have reused solder fittings many times before when modifying pipework without any problems whatsoever.

You will be suggesting that as all of his pipework is 10 years old, that it all needs replacing next.

No need for a new solder fitting and new pipe, it was just badly soldered in the first place - easily rectified.

Well there is money saving and there is money saving, I have to reciprocate and disagree with you. The reason it leaked in the 1st place was because it was badly soldered or badly cleaned, (or it was a 2nd hand fitting then;);)) But the point it it will have corroded to some extent at the point of leak and cleaning that up will require both more effort and more material removing to get it clean again, making the fitting looser which again increases the chance of poor soldering.

Yes of course I've salvaged old fittings, who hasn't, but only at 7pm on a sat night when I can't get a new 1.

I'm guessing 50p can be saved, if the OP has a blow torch he probably has a bit of pipe kicking around, why screw about desoldering etc
