As I have a bit of free time on my hands..., and my knee now lets me do a tiny bit, I'm going to put a leadloc on my mains, so I can t off for a outside (front), tap.
OD of lead is approx 20mm, so I thought 1/2". Had to look it up to make sure...  Looking for a couple, I've seen 7lb & 6lb. Obviously I'm going for the higher number!  , but before I do, can the far more knowledgeable than I, tell me what the lb means? |

It refer's the wieght of the lead Karl which in turn makes the higher wieghted one is a little bit thicker.
If you get the 6lb leadlock you'll have to get your shavehook on it to cut the pipes diameter down a bit to make it fit, that's if it's 7lb lead.

Thank you both! I did wonder if it was weight, by foot?, but no real idea. (Generally... !) I still love learning! This place has given me so much to get my mushy grey matter going over!  |

edited to correct yard.

When you take the lead-lock apart on the lead side of it take careful note of the order and position of the grab-ring and seals so that you can put them back in the same (reverse order) order.
A little tip if your finding reducing the diameter of the lead with that shave hook too hard work you can open up that split ring a little bit with your grips making it larger so it will go on the lead more easily.

Thanks CF. I looked at Toms suggestion, but too pricy!
The mains drops down 18" then runs along the floor to the back of the house. I'd rather have the new copper clipped to the joist, but not sure how the lead will bend after all these years... I could leave well alone, but that means running pipe back to the front. Is it worth doing as much as possible in 22mm then 15? I have A LOT of 22mm... |

Here's the sizes,
Old lead pipe is measured by internal diameter the outside diameter governs the weight per yard as follows.
measurements to nearest 1/64"
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)

Thanks Arfur!
I measured the od as just over 20mm, so allowing for my dodgy eysight, it's 5lb. I could only get a 6lb leadloc.
Just bought a 15-21 transition coupling, £18.45 delivered. Will wait until it arrives before cutting the lead! Just in case  |
