wiped lead joint

[plumdum]

Hi, fixing a copper pipe to lead pipe involves a 'wiped joint'.
But how do you do a wiped joint properly?
thanks.

you wipe out a lead-lok from the bag.

You shouldn't do wiped joints its against the water regs. I don't carry leadloks because there a bit expensive and I don't use them that often. They do come in different sizes because of the weight of the lead.

What you need to do is get the one that is the closest fit and then file the lead down (evenly) for the lead lock to fit! follow the instructions...

You are quite OK to do wiped lead joints for non-drinking water applications.

Forget leadloks - try the new Philmac universal coupling - far easier.

The following is a simplified description of joining lead to copper. It is somewhat of a skill which requires practice, and in reality is only done today in the chemical industry.

WIPED LEAD JOINT -

Clean inside the lead pipe and open up the end of the bore so it fits neatly over the 15mm copper pipe. Clean again with wire brush so it is bright.

Clean the outside of the copper pipe and apply flux (traditional paste flux) to both the inside of the lead pipe and the outside of the copper pipe.

Knock the copper pipe into the lead (the copper end needs to be turned over around the edge

Heat the whole area evenly then concentrate more on the copper, applying solder (leaded, lower melting point solder) to the joint.

Make sure the joint is full of solder and as much as it will take.

Clean off with wire wool.

Think maybe tin copper pipe end first before placing in lead pipe,just flux end and heat and cover in solder,then when doing joint in lead, less heat required

Then when finished wipe with wet oily,dirty rag to cool joint down,it makes joint look like it was done before regs changed........ooooh.....only kidding

I remember seeing my grandpa show me how to make a proper wiped joint of lead to lead using a parrafin torch and moleskin but it was so long ago I can't really remember how it was done. Lead to copper is relatively simple.

I learnt wiped joints during my City & Guilds apprenticeship in the early '70s

The key is to use Frys plumbing solder which stays 'plastic' and can be wiped with a moleskin cloth well impregnated with tallow.

Mind you, I don't know where or if you can get such things now. BTW, for any animal lovers reading, it isn't made from moles, just thick soft cotton cloth folded over enough times so you don't burn your hand

no one has even mentioned cardwire and black or a turnpin or a shave hook
cant belive how fast its all changed i probally had to do a wiped joint at least once a week your wiring kit was always with you
on reflection its not that fast 35years

 

[WHPES]

Few plumbers posess those items now. I have a set of turnpins and a shave hook I inherited from my grandpa.

use a lead lock, dead easy. compression fitting.

when i was training in 81, i did a wipe joint with lead in a vice. put on to much heat and all the grade d solder fell off and landed in my hand, that hurt.
