The line runs thru the back wall thru the sun room to outside to the hose.
The problem is well has been for years.
I had a plumber reverse the direction of the original line it went out side the sun porch to the middle of the house were the hot tub was.
Ir ran out the wall and down along the ground line.no problems ever there
He split it and ran the new line up under the ceiling then down to the hose connection outside. I dig a 200 ft trench and dropped in a line to the back of the property with a hose connection.
I'm going to pull all this in the fall. And run the line down across the floor line with a drain line for next year.
