Hey IaGary

The recirculation water line is 1" black plastic that comes a roll.

There are 4 400' rolls.

We dug a pit 7' deep 16 foot wide and 100 foot long. The four lines are laid in there in loops so it looks like this looking from the top down.

The straight lines represent the lines to and from the house 50 foot from the pit.

There are no splices outside the house each 400 foot makes acomplete circle out and back into the house.

There is a manifold to join the four lines into one in the house.

I can email pictures of the plumbing inside of the house if you would like.
