I still have a length of lead piping supplying my cold water and I would like to replace it with copper along with fitting a new stopcock as the supply enters the house. I am fairly confident about soldering the copper piping and joining the new supply into existing copper plumbing. However, I am concerned about joining the copper pipe to the lead pipe, either before or after the stopcock. Can I use a compression coupling for this because I am not confident about trying to solder lead to copper?
Thanks to both for the replies. I am aware of the issue surrounding lead in drinking water but for a variety of reasons replacement of all the pipework back to the supply is not feasible. I am looking at replacing as much as possible within my house. I have located a website advertising leadlok compression fittings - all I need to do now is decide whether my lead pipe is 5lb, 7lb or 9lb!
You may wonder - why not get a plumber? I have contacted around 10 companies in Aberdeen, 3 have come to look at the job but only one has estimated - a very high estimate by my reckoning. I do wonder whether increasing regulation takes into account the difficulties of finding suitably qualified tradesmen!
Have you had a price of youl local water authority ,shame your not closer as i've been replacing lead water pipes for 14years and fix underground leaks and charge a lot less than the the water companies !!
