under the house???you can see it if you tear out the walls,, and I have torn out the walls for the first time on dozens of houses built before 1920 including the one I grew up in and the one I currently live in but it didnt have inside plumbing until 1973,,as a person thats worked on houses for 50 yrs and been in thousands of them mostly older ones I have never once seen a lead water pipe in a house,,,you didnt give an accurate rant,,Yes Americans, lead has been used for pressure water piping.
And yes, it can withstand pressure required in a water supply system.
Pb. as in plumbing!
This is another one that can stand alongside the American bullshit of the Covid vaccines killing people.
America can't possibly compete with China if this sort of demonstration of ignorance is not stopped!
they are iron and lead combos,,, not just lead,,
No, the cast iron pipe with lead just in the joints are only used for waste water.
Cast iron is neve used for supply lines.
But pure lead was the main choice for cold water supply lines before 1920 or so,
How many homes, built before 1920, are still in use daily as residential property?
Probably about a third of all housing is still using these old lead pipes, and it not only is too expensive to replace them, but there is no reason to, since old lead pipes do not normally add lead to the water. It is only hot water in the home or exceptionally acidic water that causes there to be any elevated lead.
Any why would you?
The easily accessible plumbing was likely switched out over 50 years ago.
Remember that lead pipe became very valuable and easily salvaged for a profit.
But the plumbing that is inaccessible is still there, is still lead, and you just can't see it.
You would have to dig a trench between the street and house to find it.
Lead plumbing is big, heavy, hard to use, and very expensive.
It was all removed when ever accessible.
But you can't see what is under the house, and if before 1920, then under the house is lead most likely.
I thought we were talking about whats in the house,, I've never seen plumbing under one,, it comes into the side and goes up,
but as I said, I have done dozens of first time remodels on houses pre 1920 and a few pre 1900 and never seen lead pipes,,
Wrong.
No plumbing comes in to the side of the house, but comes from underneath.
It comes up through the basement floor.
To avoid shifts, freezes, foundation trenches, etc., it is usually over 10' deep.
You want to go under the foundation footing, not through the foundation or basement wall.
But in warmer climates, it could be shallower if slab construction is commonly used instead of basements.
There used to be some lead pipe inside the houses, but the price of lead went through the roof during WWII, so it all got ripped out where ever it was accessible.
thats funny when I look in my basement the pipes come out of the wall not the floor and only about 3-4 ft deep,, not sure what your frost line is,,
and its that same way in most if not all of the houses I've been in,,,
