It's an expensive house built about 10 years ago.
She's sent me two pictures.
One is of two parallel 2-inch white plastic pipes next to each other that are going horizontally across the ceiling, have right angle curves that point the pipes up, have 2 or 3-inch straight pieces, then right angle curves that point through the wall to the outside of the basement
You can see a floor joist from the floor above and the silver-colored insulation on the inside of her basement wall.
(Do they now enclose the high and low pressure AC hoses in PVC pipes like this? That's what it seems like it is.) The AC was on yesterday, but it wasn't that hot out (90) and it shouldn't have been running that much. The house has an AC at each end of the house.
(It's a royal pain for me to post the pictures. )
The second picture from her phone is darker, perhaps underexposed, but the more I look at it the more I can see. It shows the nearer 2 or 3-inch straight piece and the entire thing is glowing red!!!! You can see some red color reflecting off the silver insulation. (Above and below are the curved sections, and they each have as thicker section where they mate with the end of the straight pieces, and those sections show as black bands at the top and bottom of the 2 or 3 inches, even though in the first picture they are the same color, white.)
She could see it glowing with the lights on in the basement, plus sunlight coming in the sliding glass door. Then the glowing got less by the time she sent me these pictures. What is glowing??????
I told her before she bought the house that it had demons, but she bought it anyhow. This is the first clear example that they are there. Can they be exorcised or is she stuck with them?
