Been to inspect a leak coming from some kitchen boxing, used my inspection camera today to have a look up the boxing that goes behind kitchen cupboards then into a dormer cavity and this is the video.
At the 6 minute mark you can see a wet reducer, then shortly after you can see what I think is a wiped lead joint with the pipe then continuing up in lead.
Is that a wiped lead joint after the 15/22 reducer? (skip to about 6 minutes in and watch past the bit where it goes dark for a few seconds)

hard to make a judgement from that Joe, they're good those cameras but you don't get a good enough view,  |

Looks like the right kind of swelling for it alright. Is it accessible at all?

It will be after the joiner takes the cupboards out on Monday for me to get to the pipes  There's another bit of the video where you can see the pipes 'clipped' to the wall, I've only ever seen that type of fastening on lead pipes, it's at about 5 minutes 22 sec on the video, it's the strap kind. |

Anyone know the regs with lead?
It's a rented property so need to be careful and make sure my insurance company can't wriggle out of it on a technicality if it goes pear shaped at some point in the future.
Can I cut the lead and fit a lead loc to reconnect to copper after the leak?
My thoughts have always been that you can't work on lead, when it goes wrong you have to remove it and replace with all copper (or plastic).

as far as i know there's no rule about fixing lead, they recommend you change it, but there is no law, as far as insurance goes, they wriggle anyway, there'll be an access on the pipeing to make it uneconomic to claim,  |

From WRAS
Water Supply Industry Interpretations and Advice
Area of Interest : Installation
Topic : Lead pipe
Title : Repairing lead pipe
Clause Reference : Regulation 2(4)
Reference Number : I25
Decision Date : February 2010
Whilst repairs using new lead pipe are prohibited under Schedule 2 paragraph 2 (1) of the the Water Supply (Water Fittings) Regulations, Byelaws in Scotland, and Guidance G2.1, and customers should be encouraged to replace such pipework, it is permissible to make repairs to lead supply pipes which were legally installed prior to its prohibition and the introduction of the Regulations/Byelaws.
Where damage is restricted to small areas on internal above ground lead pipe repairs using lead free solder are acceptable. For all other types of installation or where the damage is more extensive pipework should be cut out and replaced with a suitable alternative pipe material or alternatively, where appropriate, by means of a repair clamp with a suitable material approved for wholesome water use. Customers should be aware that repairs to lead pipes, especially those exposing the water to a freshly cut lead surface, may temporarily result in raised lead concentrations, and so should be flushed before use whilst elevated lead levels occur.

Arfur supplied us with the legal jargon, which means its ok to fix it with a leadloc, but don't solder it because that contains lead, and even if its lead free solder, you must not use it cos leads not good for you, even when the solder is lead free, If any one can make sense of that, put it on a post card and send it to,

Here are the old lead pipe diameters jcplumb, handy to know,
Old lead pipe is measured by internal diameter the outside diameter governs the weight per yard as follows.
the imperial measurements to nearest 1/64", the metric OD is accurate,
1/2" Internal dia
5lb =53/64" o/dia ( 21.83mm)
6lb= 7/8" o/dia (22.23mm)
7lb= 59/64 o/dia ( 23.42mm)
9lb =1-1/64" o/dia (25.8mm)
------------------------------------------------------------------------------
3/4" internal dia
6lb= 1-3/64" o/dia (26.59mm)
8lb =1-1/8" o/dia ( 28.58mm)
9lb= 1-5/32" o/dia (29.37mm)
11lb= 1-15/64" o/dia (31.35mm)
12lb= 1-17/64" o/dia (32.15mm)
15lb =1-23/64" o/dia 34.53mm)
