Hi all.
I have a lead (Pb) water supply to an outside toilet in the back yard.
I am going to remove the toilet and then to put a tap on the
old lead supply pipe.
My question is, can I use a compression adapter fitting to convert to
copper?
Also, I've seen B.E.S. have lead to copper connectors but they specify
'lead poundage'
e.g.
Lead to Copper
Part No. Description Unit Price Qty
10270 3/8" x 5 lb lead to 15 mm compression £2.05

10271 1/2" x 6 lb lead to 15 mm compression £2.76

10272 1/2" x 7 lb lead to 15 mm compression £2.60

10273 3/4" x 9 lb lead to 22 mm compression £4.73
The outer diameter of my lead pipe is about 3/4" but
how can I tell which poundage my lead pipework is?

In your place I cut out a section of the lead pipe and took it to the
plumbers' merchant to get a matching fitting. As you have a 'live' setup you
may not have that luxury.

The fitting dimension will be the internal pipe diameter so your 3/4" o/d
pipe will defo not be the 3/4" 9lb, more likely the 3/8" but what the hey,
when you can buy all 3 possible fittings for a tenner inc vat (& maybe
postage) then get the lot and you know you will have the right one for the
job when you start cutting the pipe.
