Here is my pennorth for what it is worth.
My family lived in a house with lead pipes. The first job in the morning was
to run the kitchen tap for some minutes "to clear the stale water out of the
pipes". Soft water from Elan Valley. I believe the mains were iron
I still have a 60' lead service pipe. The first thing that happens in the
morning is the toilet is flushed, so the water lurking in the lead pipe
overnight ends up in the cistern which is close to the mains inlet. We used
to have hard water from Parkmill which could have coated the service pipe.
We now have soft water from Felindre. The mains are iron and asbestos
cement.
I have no signs of any ill health that is likely to have been caused by lead
and I am over 80. I do drink quite a lot of milk.

Dear Trevor,
An interesting question and one I've explored in my thesis and
beyond. Lead is dissolvable to an extent, which can cause problems.
What are your housepipes made of and where does the water come
from? Are you in a hard or soft water area? What exactly are you doing
in the garden?
There are a few 'learned behaviours' that warded off poisoning
when using lead, but these were mostly lost during the 20th century.
I'd be interested to hear the outcomes in your investigation,
Heather
