I would like to ask if you could explain the meaning to the word CLAD.
As in a window. What is a clad combination?
If you have a illistration it would be helpful.
Also does anyone ever inspect for a palmer valve that is supposedly in a drain.
The valve is in older homes in the floor drain? I have never seen one to inspect.
I asked this to my cousin who is a plumber. He had no idea what I was talking about.
The reason I ask is my report system includes this information.
